Configuring EVPN-MPLS Active-Standby Multihoming

date_range 20-Dec-24

arrow_backward

arrow_forward

You can configure multihoming in active-standby redundancy mode in an Ethernet VPN (EVPN) fabric with MPLS. This mode enables the device to autodiscover Ethernet segments, construct Ethernet segment routes, and assign Ethernet segment identifier (ESI) labels.

Note:

We support active-standby multihoming in EVPN fabrics only with MPLS.

QFX Series switches support EVPN-VXLAN with active-active multihoming; they don't support EVPN with MPLS or multihoming in active-standby mode.

When configuring active-standby EVPN multihoming on supported devices, be aware of the following limitations:

An interface or ESI can be attached to more than one EVPN instance (EVI), with a maximum limit of 200 EVIs per ESI.
For an EVPN routing instance, only one logical interface per physical interface or ESI can be attached to an EVI.
For a virtual switch routing instance, only one logical interface per physical interface or ESI can be configured under a bridge domain.

All the PE routers in the network topology that support this feature should be running Junos OS Release 14.1 or later releases, which are based on EVPN draft-ietf-l2vpn-evpn-03. Junos OS releases prior to 14.1 support the older version of the EVPN draft, causing interoperability issues when Junos OS Release 14.1 and a previous release are running.

Before you begin:

Configure the router interfaces.
Configure the router ID and autonomous system number for the device.
Configure OSPF or any other IGP protocol.
Configure a BGP internal group.
Include the EVPN signaling network layer reachability information (NLRI) to the internal BGP group.
Configure LDP.
Configure MPLS.
Configure RSVP MPLS LSP or GRE tunnels.

To configure the PE device:

Enable EVPN active-standby multihoming on the multihomed interfaces.

content_copy zoom_out_map
[edit interfaces]
user@PE1# set interface-name vlan-tagging
user@PE1# set interface-name encapsulation flexible-ethernet-services
user@PE1# set interface-name esi esi-value
user@PE1# set interface-name esi single-active
user@PE1# set interface-name unit 0 encapsulation vlan-bridge
user@PE1# set interface-name unit 0 vlan-id VLAN-ID

For example:

content_copy zoom_out_map
[edit interfaces]
user@PE1# set ge-0/0/4 vlan-tagging
user@PE1# set ge-0/0/4 encapsulation flexible-ethernet-services
user@PE1# set ge-0/0/4 esi 00:22:44:66:88:00:22:44:66:88
user@PE1# set ge-0/0/4 esi single-active
user@PE1# set ge-0/0/4 unit 0 encapsulation vlan-bridge
user@PE1# set ge-0/0/4 unit 0 vlan-id 300

Configure the routing instance for the active-standby mode of redundancy.

The active-standby multihoming can be configured under any EVPN routing-instance. We support evpn, virtual-switch, and mac-vrf instance types in active-standby EVPN multihoming. The vrf routing-instance is configured to illustrate the EVPN IRB functionality, in addition to multihoming, and is not mandatory for the active-standby EVPN multihoming feature to work. For example:

content_copy zoom_out_map
Virtual-switch Routing Instance
[edit routing-instances]
user@PE1# set virtual-switch-instance instance-type virtual-switch
user@PE1# set virtual-switch-instance protocols evpn extended-vlan-list VLAN-ID
user@PE1# set virtual-switch-instance bridge-domains bridge-domain-name domain-type bridge
user@PE1# set virtual-switch-instance bridge-domains bridge-domain-name vlan-id VLAN-ID
user@PE1# set virtual-switch-instance bridge-domains bridge-domain-name interface interface-name
user@PE1# set virtual-switch-instance bridge-domains bridge-domain-name routing-interface interface-name
user@PE1# set virtual-switch-instance route-distinguisher route-distinguisher-value
user@PE1# set virtual-switch-instance vrf-target vrf-target

content_copy zoom_out_map
EVPN Routing Instance
[edit routing-instances]
user@PE1# set evpn-instance instance-type evpn
user@PE1# set evpn-instance vlan-id VLAN-ID
user@PE1# set evpn-instance interface interface-name
user@PE1# set evpn-instance routing-interface interface-name
user@PE1# set evpn-instance route-distinguisher route-distinguisher-value
user@PE1# set evpn-instance vrf-target vrf-target

content_copy zoom_out_map
VRF Routing Instance
[edit routing-instances]
user@PE1# set vrf-instance instance-type vrf
user@PE1# set vrf-instance interface interface-name
user@PE1# set vrf-instance route-distinguisher route-distinguisher-value
user@PE1# set vrf-instance vrf-target vrf-target

Verify and commit the configuration.

For example:

content_copy zoom_out_map
[edit routing-instances]
user@PE1# set ALPHA instance-type virtual-switch
user@PE1# set ALPHA route-distinguisher 10.255.0.1:100
