Description (partial)

OSPFv3 supports OSPFv3 MPLS TE Tunnels over IPv4 MPLS TE infrastructure.

It may be seen that cost of the tunnel switches between undetermined and configured cost, link via tunnel is added/removed to/from router LSA, SPF runs periodically.

Affected is only OSPFv3 MPLS TE tunnel configured with forwarding-adjacency, not tunnel with autoroute-announce.
OSPFv3 cost of the OSPFv3 MPLS TE Tunnels is configured and it's lower than cost of the native path.
