rfc1583-compatibility (OSPF)

Configures compatibility with RFC 1583.

Synopsis rfc1583-compatibility

no rfc1583-compatibility

Operands None

Defaults OSPF is compatible with RFC 1583 (OSPFv2).

Command Modes OSPF VRF router configuration mode

Description Use this command to enable or disable compatibility with RFC 1583. 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.

Usage Guidelines Enter no rfc1583-compatibility to disable compatibility with RFC 1583.

Examples To disable compatibility with RFC 1583:

switch# configure

switch(config)# rbridge-id 5

switch(config-rbridge-id-5)#router ospf

switch(config-router-ospf-vrf-default-vrf)# rfc1583-compatibility
