Re: [OSPF] OSPF Digest, Vol 68, Issue 8

Hi OSPF group members,



Is this the objective of using Instance Id in OSPFv2.



Instance id will be used If interface having more than one addresses, so we
need to configure different subnets in router interface (Using secondary
address cli command).



So we can connect multiple areas on single link, No need different physical
connection for each area.


Thanks,
Thiru
