ExtremeWare XOS 11.5 Command Reference Guide
1635
configure ospfv3 routerid
configure ospfv3 {domain <domainName>} routerid [automatic | <router-
identifier>]
Description
Configures the OSPFv3 router ID. If automatic is specified, the switch uses the highest IPv4 interface
address as the OSPFv3 router ID.
Syntax Description
Default
Automatic.
Usage Guidelines
Each switch that is configured to run OSPFv3 must have a unique router ID. The router ID is a four-
byte, dotted decimal number, like an IPv4 address. Even though the IP address format has changed
from IPv4 to IPv6, the router ID format has not. It is recommended that you manually set the router ID
of the switches participating in OSPFv3, instead of having the switch automatically choose its router ID
based on the highest interface IPv4 address (if it exists). Not performing this configuration in larger,
dynamic environments could result in an older link-state database remaining in use.
This command is accepted only when OSPFv3 is globally disabled.
NOTE
Do not set the router ID to 0.0.0.0.
Example
The following command sets the router ID to 10.1.6.1:
configure ospfv3 routerid 10.1.6.1
