Command History
Usage Guidelines EIGRP automatically selects an IP address to use as the router ID when an EIGRP process is started. The
highest local IP address is selected and loopback interfaces are preferred. The router ID is not changed
unless the EIGRP process is removed with the no router eigrp command or if the router ID is manually
configured with the eigrp router-id command.
The router ID is used to identify the originating router for external routes. If an external route is received
with the local router ID, the route is discarded. The router ID can be configured with any IP address with
two exceptions; 0.0.0.0 and 255.255.255.255 are not legal values and cannot be entered. You should
configure a unique value for each router.
This command requires the LAN Base Services license.
Examples This example shows how to configure 192.168.0.3 as a fixed router ID:
switch# configure terminal
switch(config)# router eigrp 209
switch(config-router)# eigrp router-id 192.168.0.3
switch(config-router)#
