Hey renee,
I would like to know if the list of requirement to establish a adjacency between 2 OSPFv3 routers is the same like OSPF (IPv4).
I know that in IPv4 we have to check:
§ Timers
§ Authentication
§ Area ID
§ Subnet
§ Subnet Mask
Stub area Flag
But in the OSPFv3 I think we need to see instance ID…
Thanks!
OSPF doesn’t have a mechanism where it exchanges information about the MTU on the interfaces that connect two OSPF neighbours. However, OSPF routers can get stuck in the Extart stage because of MTU issues. More information about this can be found at the following Cisco documentation.
