Command Modes Router configuration mode
Command History
Usage Guidelines To minimize the chance of routing loops, all Open Shortest Path First (OSPF) routers in an OSPF routing
domain should have RFC compatibility set identically.
Because of the introduction of RFC 2328, OSPF Version 2, the method used to calculate summary route
costs has changed. Use the no rfc1583compatibility command to enable the calculation method used
per RFC 2328.
This command requires the LAN Enterprise Services license.
Examples This example specifies that the router process is compatible with RFC 1583:
switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
switch(config)# router ospf 2
switch(config-router)# rfc1583compatibility
switch(config-router)#
Release Modification
5.0(3)A1(1) This command was introduced.
