Configure LDP Remote Loop-Free Alternate (RLFA)
The LDP RLFA configuration process can be divided into the following tasks:
1. Enable label-switching on the interface on NSM.
2. Establish ISIS routing between the nodes (to distribute reachability information within the MPLS cloud)
3. Configure ISIS RLFA on Source node
4. Enabling LDP on an interface in the LDP daemon
5. Configure LDP FRR with Auto-targeted-session (Allow creating TLDP session dynamically)
6. Enable BFD interval globally and for all ISIS enabled interfaces
Note: Faster convergence can be achieved with lower BFD interval enabled globally.
Note: Dynamically created RLFA T-LDP sessions will be removed only after disabling LDP auto-targeted-session CLI or LDP FRR.
Note: When targeted-peer ipv4 CLI is configured with auto-targeted-session CLI, T-LDP session created for targeted-peer only remove after disabling auto-targeted-session CLI.
Note: After Enabling ISIS RLFA, Both LFA and RLFA computation will be done and RLFA path will be preferred to provide node-protection.
Note: Better convergence can be achieved with LDP-IGP-SYNC enabled.
Assumptions and limitations
• RLFA Backup path computation will be supported only via IGP as IS-IS.
• Only LDP(MPLS) will be used as a tunnel mechanism to reach a Remote-LFA repair node.
• Only IPv4 protocol is supported.
• RFC 7916 [LFA-MANAGE] is not supported.
• ECMP will not be supported for RLFA next-hop.
Topology
Figure 39-19 shows the configuration required to enable the RLFA feature.
