Example: Configure IPSec VPN in Active-Active Multinode High Availability in a Layer 3 Network
SUMMARY This example shows how to configure and verify IPsec VPN for active-active Multinode High Availability setup.
Overview
In Multi-Node High Availability, participating SRX Series Firewalls operate as independent nodes in a Layer 3 network. The nodes are connected to adjacent infrastructure belonging to different networks. An encrypted logical interchassis link (ICL) connects the nodes over a routed network. Participating nodes backup each other to ensure a fast synchronized failover in case of system or hardware failure.
You can operate Multinode High Availability in active-active mode with support of multiple services redundancy groups (SRGs). In this mode, some SRGs remain active on one node and some SRGs remain active on another node.
Multinode High Availability supports IPsec VPN in active-active mode with multiple SRGs (SRG1+). In this mode, you can establish multiple active tunnels from both the nodes, based on SRG activeness. Multinode High Availability establishes IPsec tunnel and performs key exchanges by associating termination IP address (which also identifies the tunnels ending on it) to the SRG. Since different SRG1+ can be in active state or in backup state on each of the devices, Multinode High Availability steers the matching traffic effectively to the corresponding active SRG1. Since different SRGs can be active on different nodes, tunnels belonging to these SRGs come up on both nodes independently.
Note:
We support a two-node configuration in the Multinode High Availability solution.
Requirements
This example uses the following hardware and software components:
Two SRX Series Firewalls (Supported devices are SRX5400, SRX5600, and SRX5800 with SPC3, IOC3, SCB3, SCB4, and RE3)
Junos OS Release 22.4R1
We've used two Juniper Networks MX Series Routing Platform as upstream/downstream routers in this example.
Before You Begin
Configure stateless firewall filtering and quality of service (QoS) as per your network requirements and have appropriate security policies to manage traffic in your network.
In a typical high availability deployment, you have multiple routers and switches on the northbound and southbound sides of the network. For this example, we are using two routers on both sides of SRX Series Firewalls. Ensure that you've configured upstream and downstream routers as per your network requirements.
Install the Junos IKE package on your SRX Series Firewalls using the
request system software add optional://junos-ike.tgzcommand. Thejunos-ikepackage is included in your Junos software packages (Junos OS Release 20.4R1 onwards).
Topology
Figure 1 shows the topology used in this example.
Figure 1: Multinode High Availability in Layer 3 Network
As shown in the topology, two SRX Series Firewalls (SRX-1 and SRX-2) are connected to adjacent routers on trust and untrust side forming a BGP neighborship. An encrypted logical interchassis link (ICL) connects the nodes over a routed network. The nodes communicate with each other using a routable IP address (floating IP address) over the network.
The SRX-03 device acts as a peer device to the Multinode High Availability setup and it establishes IPsec VPN tunnels with SRX-01 and SRX-02 devices.
You'll perform the following tasks to build a Multinode High Availability setup:
- Configure a pair of SRX Series Firewalls as local and peer nodes by assigning IDs.
- Configure services redundancy groups (SRG1 and SRG2).
- Configure a loopback interface (lo0.0) to host the floating IP address and to reach the peer gateway. Using the loopback interface ensures that at any given point, traffic from the adjacent routers will be steered toward the floating IP address (that is, toward the active node).
- Configure IP probes for the activeness determination and enforcement
- Configure a signal route required for activeness enforcement and use it along with the route exists policy.
- Configure a VPN profile for the high availability (ICL) traffic using IKEv2.
- Configure BFD monitoring options
- Configure a routing policy and routing options
- Configure interfaces and zones according to your network requirement. You must allow services such as IKE for link encryption and SSH for configuration synchronization as host-inbound system services on the security zone that is associated with the ICL.
-
Create a group configuration for IPsec VPN on SRX-01 and SRX-02 devices to set up a tunnel with VPN peer device (SRX-03). Configuration groups enable you to apply common elements that are reused within the same configuration.
- Configure IPsec VPN options to establish tunnels with SRX-03 device and enable IPsec VPN configuration synchronization on both the devices (SRX-01 and SRX-02) by using [groups] option.
- Configure VPN peer device with IPsec VPN options.
For interchassis link (ICL), we recommend the following configuration:
-
In general, you can use Aggregated Ethernet (AE) or a revenue Ethernet port on the SRX Series Firewalls to setup an ICL connection. In this example, we've used GE ports for the ICL. We've also configured a routing instance for the ICL path to ensure maximum segmentation.
- Do not to use the dedicated HA ports (control and fabric ports) if available on your SRX Series Firewall).
- Set MTU of 1514
- Allow the following services on the security zone associated with interfaces
used for ICL
-
IKE, high-availability, SSH
-
Protocols depending on the routing protocol you need.
-
BFD to monitor the neighboring routes.
-
You can configure the following options on SRG0 and SRG1+:
You can configure the following options on SRG0 and SRG1:
-
SRG1: Active/backup signal route, deployment type, activeness priority, preemption, virtual IP address (for default gateway deployments), activeness probing and process packet on backup.
-
SRG1: BFD monitoring, IP monitoring, and interface monitoring options on SRG1.
-
SRG0: shutdown on failure and install on failure route options.
When you configure monitoring (BFD or IP or Interface) options under SRG1, we recommend not to configure the shutdown-on-failure option under SRG0.
-
SRG1: Active/backup signal route, deployment type, activeness priority, preemption, virtual IP address (for default gateway deployments), activeness probing and process packet on backup.
-
SRG1: BFD monitoring, IP monitoring, and interface monitoring options on SRG1.
-
SRG0: shutdown on failure and install on failure route options.
When you configure monitoring (BFD or IP or Interface) options under SRG1, we recommend not to configure the shutdown-on-failure option under SRG0.

Configuration
Step-by-Step Procedure
We're showing the configuration of SRX-01 in the step-by-step procedure.
The following example requires you to navigate various levels in the configuration hierarchy. For instructions on how to do that, see Using the CLI Editor in Configuration Mode in the CLI User Guide.
Configure Interfaces.
[edit] user@srx-1# set interfaces ge-0/0/2 description inter_chassis_link user@srx-1# set interfaces ge-0/0/2 unit 0 family inet address 10.22.0.2/24 user@srx-1# set interfaces ge-0/0/3 description untrust user@srx-1# set interfaces ge-0/0/3 unit 0 family inet address 10.3.0.2/24 user@srx-1# set interfaces ge-0/0/4 description trust user@srx-1# set interfaces ge-0/0/4 unit 0 family inet address 10.5.0.1/24
Use ge-0/0/3 and ge-0/0/4 interfaces to connect to the upstream and downstream routers and use ge-0/0/2 interface to set up the ICL.
Configure the loopback interfaces.
[edit] user@srx-1# set interfaces lo0 apply-groups-except global user@srx-1# set interfaces lo0 description untrust user@srx-1# set interfaces lo0 unit 0 family inet address 10.11.0.1/32 user@srx-1# set interfaces lo0 unit 0 family inet address 10.12.0.1/32 user@srx-1# set interfaces st0 unit 1
Assign IP address 10.11.0.1 and 10.12.0.1 to the loopback interface. We'll use 10.11.0.1 as the floating IP address and 10.12.0.1 as IKE gateway address.
Configure security zones, assign interfaces to the zones, and specify the allowed system services for the security zones.
[edit] user@srx-1# set security zones security-zone vpn host-inbound-traffic system-services ike user@srx-1# set security zones security-zone vpn host-inbound-traffic protocols all user@srx-1# set security zones security-zone vpn interfaces st0.1 user@srx-1# set security zones security-zone untrust host-inbound-traffic system-services ike user@srx-1# set security zones security-zone untrust host-inbound-traffic system-services ping user@srx-1# set security zones security-zone untrust host-inbound-traffic protocols bfd user@srx-1# set security zones security-zone untrust host-inbound-traffic protocols bgp user@srx-1# set security zones security-zone untrust interfaces lo0.0 user@srx-1# set security zones security-zone untrust interfaces ge-0/0/3.0 user@srx-1# set security zones security-zone trust host-inbound-traffic system-services all user@srx-1# set security zones security-zone trust host-inbound-traffic protocols all user@srx-1# set security zones security-zone trust interfaces ge-0/0/4.0 user@srx-1# set security zones security-zone icl_zone host-inbound-traffic system-services ike user@srx-1# set security zones security-zone icl_zone host-inbound-traffic system-services ping user@srx-1# set security zones security-zone icl_zone host-inbound-traffic system-services high-availability user@srx-1# set security zones security-zone icl_zone host-inbound-traffic system-services ssh user@srx-1# set security zones security-zone icl_zone host-inbound-traffic protocols bfd user@srx-1# set security zones security-zone icl_zone host-inbound-traffic protocols bgp user@srx-1# set security zones security-zone icl_zone interfaces ge-0/0/2.0
Assign the interfaces ge-0/0/3 and ge-0/0/4 the trust and untrust zones respectively. Assign the lo0.0 interface to the untrust zone to connect over the IP network. Assign the interface ge-0/0/2 to the ICL zone. You use this zone to set up the ICL. Assign the secure tunnel interface to the VPN security zone.
- Configure both local node and peer node details such as node ID, lP addresses of local node and peer node, and the interface for the peer node.
[edit] user@srx-1# set chassis high-availability local-id 1 user@srx-1# set chassis high-availability local-id local-ip 10.22.0.2 user@srx-1# set chassis high-availability peer-id 2 peer-ip 10.22.0.1 user@srx-1# set chassis high-availability peer-id 2 interface ge-0/0/2.0
You'll use the ge-0/0/2 interface for communicating with the peer node using the ICL.
Attach the IPsec VPN profile IPSEC_VPN_ICL to the peer node.
[edit] user@srx-1# set chassis high-availability peer-id 2 vpn-profile ICL_IPSEC_VPN

Configure the active signal route 10.39.1.1 (SRG1) and 10.49.1.1 (SRG2) with the route match condition (
if-route-exists). The Multinode High Availability adds this route to the routing table when the node moves to the active role. The node also starts advertising the higher preference route. Configure the backup signal route (10.39.1.2 and 10.49.1.2) to advertise the backup node with a medium priority. In case of any failures, the high availability link goes down and the current active node releases its primary role and removes the active-signal-route. Now the backup node detects the condition through its probes and transitions to the active role. The route preference is swapped to drive all the traffic to the new active nodeConfigure BFD peering sessions options and specify liveness detection timers.

The IPsec SA pair for each threads in PIC.
HA link encryption mode (as shown in the following line):
HA Link Encryption Mode: Multi-NodeAuthentication and encryption algorithms used
CAUTION:
The IP range (180.100.1.x) shown in the command output serves as the ICL IPsec traffic selector. The system dynamically assigns this IP range, and it is essential not to alter or modify it. Additionally, BFD (Bidirectional Forwarding Detection) will be automatically enabled for the broader 180.x.x.x IP range.
Verify Link Encryption Tunnel Statistics
Purpose
Verify link encryption tunnel statistics on both active and backup nodes.
Action
Run the following command on SRX-01:
user@srx-01> show security ipsec statistics ha-link-encryption ESP Statistics: Encrypted bytes: 106294156 Decrypted bytes: 51961287 Encrypted packets: 979531 Decrypted packets: 989651 AH Statistics: Input bytes: 0 Output bytes: 0 Input packets: 0 Output packets: 0 Errors: AH authentication failures: 0, Replay errors: 0 ESP authentication failures: 0, ESP decryption failures: 0 Bad headers: 0, Bad trailers: 0 Invalid SPI: 0, TS check fail: 0 Exceeds tunnel MTU: 0 Discarded: 0
Meaning
If you see packet loss issues across a VPN, you can run the show security ipsec statistics ha-link-encryption command several times to verify that the encrypted and decrypted packet counters are incrementing. You should also check whether the other error counters are incrementing.
Use the clear security ipsec security-associations ha-link-encryption command to clear all IPsec statistics.
Verify Interchassis Link Active Peers
Purpose
View only ICL active peers, but not regular IKE active peers.
Action
Run the following commands on SRX-01 and SRX-02 devices:
SRX-1
user@srx-01> show security ike active-peer ha-link-encryption Remote Address Port Peer IKE-ID AAA username Assigned IP 10.22.0.1 500 10.22.0.1 not available 0.0.0.0
