Configuring Route Recursion over SR Tunnels

If SR tunnels are used to carry service traffic, the function to recurse routes over SR tunnels must be configured.

You can configure a tunnel policy or an SR-MPLS BE tunnel-preferred policy to recurse routes over SR tunnels.

Configure a tunnel policy on PEs, DC-GWs, and L2GW/L3GWs and apply the tunnel policy. You can choose to recurse routes over SR-MPLS BE or SR-MPLS TE tunnels. For configuration details, see Configuring and Applying a Tunnel Policy.
If both the LDP and SR-MPLS BE tunnels are deployed and users want route recursion over SR-MPLS BE tunnels, configure an SR-MPLS BE tunnel-preferred policy on each device.
