OSPF6 over IPv6 VTI Tunnel Interfaces



  • Has anyone managed to get dynamic OSPF6 IPv6 routing running over VTI tunnel interfaces? I have a pair of test firewalls running. IPv4 on the WAN, IPv4 and IPv6 on the LAN. IPsec tunnel with VTI interfaces working correctly. Static IPv6 routes work without issue but OSPF6 routing for IPv6 fails to create a neighbour relationship. IPv4 comes straight up without issue. It seems the issue is the VTIv6 gateway is forever in a pending status. Note, this is using RFC4193 address space. Using the FRR routing package. Looks like it could be a potential bug.
