BGP label route resolution using segment routing tunnels

Configure the following CLI commands to enable the resolution of RFC 3107 BGP label route prefixes using SR tunnels to BGP next-hops in the TTM.

Note:

The 7210 SAS-Mxp, 7210 SAS-R6, 7210 SAS-R12, and 7210 SAS-Sx/S 1/10GE do not support RFLA with BGP 3107 labeled tunnel routes.

configure>router>bgp>next-hop-resolution
        labeled-route-transport-tunnel
            [no] family family
                resolution {any | disabled | filter}
                resolution-filter
                    [no] sr-isis
                    [no] sr-ospf
                exit
            exit
        exit
    exit

If the resolution option is explicitly set to disabled, the default binding to LDP tunnel is used. If resolution option is set to any, a supported tunnel type from the BGP label route context is selected following the TTM preference.

The following tunnel types are supported in a BGP label route context and are listed in order of preference:

RSVP
LDP
segment routing

When sr-isis or sr-ospf is configured using the resolution-filter option, a tunnel to the BGP next-hop is selected in the TTM from the lowest numbered IS-IS or OSPF instance.

See the BGP chapter for information about BGP label route resolution using SR tunnels.
