Deriving the Router ID
The router ID defaults to the address specified in the system interface command. If the system
interface is not configured with an IP address, then the router ID inherits the last four bytes of the
MAC address. The router ID can also be manually configured in the
config>router router-
id
context. On the BGP protocol level, a BGP router ID can be defined in the
config>router>bgp router-id
context and is only used within BGP.
Note that if a new router ID is configured, protocols are not automatically restarted with the new
router ID. The next time a protocol is initialized the new router ID is used. An interim period of
time can occur when different protocols use different router IDs. To force the new router ID, issue
the
shutdown
and
no shutdown
commands for each protocol that uses the router ID, or restart
the entire router.
Use the following CLI syntax to configure the router ID:
CLI Syntax:
config>router
router-id router-id
interface ip-int-name
address { ip-address/mask | ip-address netmask } [broad-
cast all-ones | host-ones ]
The following example displays a router ID configuration:
A:ALA-4>config>router# info
#------------------------------------------
# IP Configuration
#------------------------------------------
interface "system"
address 10.10.0.4/32
exit
. . .
router-id 10.10.0.4
