segment-routing ipv6 (BGP-IPv6 unicast address family view)

Function

The segment-routing ipv6 best-effort command enables a device to perform public network route iteration to an SRv6 BE based on SIDs carried in routes.

The segment-routing ipv6 best-effort command enables a device to perform public network route iteration to an SRv6 TE Policy based on SIDs carried in routes.

The undo segment-routing ipv6 best-effort, undo segment-routing ipv6 traffic-engineer and undo segment-routing ipv6 best-effort traffic-engineer command restores the default configuration.

By default, this function is disabled.

Usage Guidelines

Usage Scenario

In an global IPv6 over SRv6 scenario, the segment-routing ipv6 { best-effort | traffic-engineer } * command enables public network routes to recurse to an SRv6 BE or TE policy based on SIDs carried in routes.

When thebest-effortandtraffic-engineerparameters both exists, if the SRv6 TE policy becomes faulty, services can use the SRv6 BE tunnel as a best-effort path.
