Example: Configuring Multiple-Instance LDP

date_range 20-Dec-24

arrow_backward

arrow_forward

The primary LDP instance is configured at the [edit protocols] hierarchy level.

You can configure a specific instance of LDP by using the ldp statement at the [edit routing-instances routing-instance-name protocols] hierarchy level. This creates an instance of LDP for the particular VRF routing instance. You must specify all the required VRF statements and apply export and import policies to your LDP instance for the configuration to commit properly.

Most of the LDP hierarchy levels available in a primary instance are also available for specific instances of LDP. However, the no-forwarding option does not work in a VRF-based instance of LDP.

Figure 1: Multiple-Instance LDP Topology Diagram

Figure 1 shows an example of a carrier-of-carriers network. CE3 and CE4 are end customer CE routers residing in AS 65010. The VPN provider in AS 65020 has three types of routers: PE3 and PE4 are PE routers that connect to the end customer, CE1 and CE2 act as the intermediate carrier CE routers, and P2 and P3 are internal transit routers. PE1 and PE2 in AS 65030 are PE routers servicing the intermediate VPN provider, and P0 and P1 are transit routers for the top-tier carrier.

To make this configuration work, you must complete three major tasks:

Configure external BGP between the VPN customer CE and the VPN provider PE.
Configure internal BGP using the VPN family between both pairs of PE routers (one IBGP connection between PE1 and PE2 and a second IBGP connection between Router PE3 and Router PE4).
Establish LDP and Interior Gateway Protocol (IGP) connections on all remaining links. This example uses OSPF as the IGP, but you can use the IGP of your choice.

Information supporting this carrier-of-carriers multiple-instance LDP example is summarized in Table 1.

Table 1: Multiple-Instance LDP Example—Routing Protocol Summary
Connection	Protocols
CE3 - PE3	EBGP family inet
PE3 - P2 - CE1	OSPF and LDP
CE1 - PE1	OSPF and LDP
PE1 - P0 - P1 - PE2	OSPF and LDP
PE1 - PE2	IBGP family inet-vpn
PE2 - CE2	OSPF and LDP
CE2 - P3 - PE4	OSPF and LDP
PE4 - CE4	EBGP family inet
PE3 - PE4	IBGP family inet-vpn

Your configuration tasks start at Router CE3 and move router by router through the first part of the VPN provider network, into the carrier AS, through the second VPN provider cluster of AS 65020, and end at the second VPN customer Router CE4.

Since Router CE3 is the first customer router, configure EBGP between Router CE3 and the connected VPN provider Router PE3. You must also advertise your loopback address into BGP with a routing policy to allow IP reachability with Router CE4.

set routing-options autonomous-system 65010

On Router PE3, the configuration tasks are more involved. You need to complete the EBGP connection to Router CE3 in a VRF instance, enable MPLS and LDP on the interface pointing toward the VPN provider Router CE1, and configure a primary instance of IBGP to reach Router PE4 at the far edge of AS 65020.

Finally, set up an outbound VRF policy that places all BGP traffic and directly connected interfaces into a BGP community and an inbound VRF policy that accepts similar BGP community traffic from Router PE4.

On core carrier Router PE1, configure a primary instance for OSPF, LDP, MPLS, and IBGP (with the family inet-vpn option) to connect the router to neighbor Router PE2. Next, implement multiple-instance LDP by establishing a secondary instance. Enable LDP and OSPF in this instance for Router PE1 to communicate with Router CE1. MPLS is not required in the secondary instance.

Finally, set up an outbound VRF policy that places all LDP traffic coming from Router CE1 into a BGP community, an export policy that sends this community traffic to Router PE2, and an inbound VRF policy that accepts similar BGP community traffic from Router PE2. This step tunnels the VPN provider’s LDP traffic into the carrier’s BGP session.

Core carrier Router PE2 is a mirror image of Router PE1. First, configure a primary instance for OSPF, LDP, MPLS, and IBGP (with the family inet-vpn option) to connect Router PE2 to neighbor Router PE1. Next, implement multiple-instance LDP by establishing a secondary instance. Enable LDP and OSPF in this instance for Router PE2 to communicate with Router CE2.

Verifying Your Work

To verify the proper operation of your multiple-instance LDP configuration, use the following commands:

show ldp database
show ldp interface
show ldp neighbor
show ldp path
show ldp route
show ldp session
show ldp statistics

The display output for these commands is the same as in previous Junos OS Releases, except for one difference. An instance name can now be used as an argument.

If you include an instance name with these commands, you display information for the specified LDP instance. For example, the command show ldp neighbor instance crockett shows all the LDP neighbors for a VRF instance named crockett. Conversely, show ldp neighbor without an instance name displays the LDP neighbors associated with the primary instance.

The following sections show the output of these commands used with the configuration example:

Router CE3 Status
Router PE3 Status
Router CE1 Status
Router PE1 Status
Router PE2 Status
Router CE2 Status
Router PE4 Status
