The ipv6 route recursive-lookup inherit-label-route enable command allows IPv6 routes to recurse to remotely leaked VPN routes.
The undo ipv6 route recursive-lookup inherit-label-route enable command disables IPv6 routes from recursing to remotely leaked VPN routes.
By default, IPv6 routes cannot recurse to remotely leaked VPN routes.
Usage Scenario
A route needs recursion if its next hop is unreachable. To allow IPv6 routes to recurse to remotely leaked VPN routes, run the ipv6 route recursive-lookup inherit-label-route enable command. After the command is run, IPv6 routes inherit the labels and Tunnel IDs of the remotely leaked VPN routes, which ensures correct traffic forwarding. This command mainly applies to BGP/MPLS IPv6 VPN scenarios.
