COMPATIBLE RFC1583
Syntax
compatible rfc1583
no compatible rfc1583
Parameters
none
Description
Use the COMPATIBLE RFC1583 command to restore the method used to
calculate summary route costs per RFC. By default, OSFP is compatible
with RFC 2328.
Prior to RFC 2328, OSPF was compliant with RFC 1583 which specified
the method for calculating the metric for summary routes based on the
minimum metric of the component paths available. RFC 2328 specifies a
method for calculating metrics based on the maximum cost. With this
change, it is possible that all of the ABRs in an area might not be upgraded
to the new code at the same time. The COMPATIBLE RFC1583 command
addresses this issue and allows the selective disabling of compatibility
with RFC 2328.
Use the no form of this command with the COMPATIBLE RFC1583
command to disable RFC 1583 compatibility.
Command Mode
Router mode
Example
The following commands set OSPF compatible to RFC 1583:
switch#configure terminal
switch(config)#router ospf 100
switch(config-router)# compatible rfc1583
