OSPF router configuration mode
OSPF router VRF configuration mode
OSPF is compatible with RFC 1583 (OSPFv2) and maintains a single best route to an autonomous system (AS) boundary router in the OSPF routing table. Disabling this compatibility causes the OSPF routing table to maintain multiple intra-AS paths, which helps prevent routing loops.
Enter no rfc1583-compatibility to disable compatibility with RFC 1583.
The following example disables compatibility with RFC 1583.
