IP Routing Features
Configuring IP Parameters for Routing Switches
on the routing switch and OSPF is restarted with a reboot. (User-Configured
loopback interfaces are always higher priority than other configured inter­
faces.) However, you prefer, you can explicitly set the router ID to any valid
IP address, as long as the IP address is not in use on another device in the
network.
N o t e To display the router ID, enter the show ip ospf CLI command at any Manager
EXEC CLI level.
ProCurve(ospf)# show ip ospf
OSPF Configuration Information
OSPF protocol : enabled
Router ID : 10.10.10.1
Example of how to display
the current router ID.

Reconfiguring the Router ID (Optional). If you want to change the
router ID setting, do the following:
1. Go to the global config context. When you do so, the CLI prompt will
appear similar to the following:
ProCurve(config)#_
2. If OSPF is not enabled, go to step 3. But if OSPF is enabled, then use no
router ospf to disable OSPF operation.
3. Use ip router-id < ip-addr > to specify a new router ID. (This IP address must
be unique in the routing switch configuration.)
4. If you disabled OSPF operation (step 2), then use router ospf to re-enable
OSPF operation.
