router-id (OSPF)

router-id (OSPF)
To use a fixed router ID for an Open Shortest Path First (OSPF) instance, use the router-id command.
To revert to the previous OSPF router ID behavior, use the no form of this command.
Syntax Description
ip-address
Command Default If this command is not configured, OSPF chooses an IPv4 address as the router ID from one of its
interfaces.
Command Modes Router configuration mode
Command History Release
5.0(3)A1(1)
Usage Guidelines Configuring a router ID ensures that EIGRP can function regardless of the interface address
configuration.
If this command is used on an OSPF instance that has neighbors, OSPF uses the new router ID at the
next reload or at a restart of OSPF.
This command requires the LAN Enterprise Services license.
Examples This example shows how to configure the router ID:
switch# configure terminal
switch(config)# router ospf 12
switch(config-router)# router-id 192.0.2.1
switch(config-router)#
