Two prefix family values of srv4 and srv6 are added to the igp-shortcut construct.
When enabled, the srv4 value allows IGP to resolve SR-ISIS IPv4 tunnels in MT=0 or SR-OSPF IPv4 tunnels over RSVP-TE LSPs used as IGP shortcuts.
When enabled, the srv6 value allows IGP to resolve SR-ISIS IPv6 tunnels in MT=0 over RSVP-TE LSPs used as IGP shortcuts.

See Family Prefix Resolution and Tunnel Selection Rules for an explanation of the rules for the resolution of SR-ISIS IPv4 tunnels, SR-ISIS IPv6 tunnels, and SR-OSPF IPV4 tunnels, and the selection of the tunnel types on a per-family basis.
