Parameter
router-id: Router ID that is a 32-bit unsigned integer.
Description
Using the router id command, you can configure the ID of a router running the
OSPF protocol. Using the undo router id command, you can cancel the router ID
that has been configured.
By default, no router ID is configured.
Router ID is a 32-bit unsigned integer that uniquely identifies a router in an OSPF
autonomous system. If the router ID specified, the configurations of OSPF can not
be set.
When the router ID is configured manually, the IDs of any two routers cannot be
identical in the autonomous system. So, the IP address of certain interface might
as well be selected as the ID of this router.
The modified router ID will not be valid unless OSPF is re-enabled.
For the related command, see ospf.
Example
Set the router ID to 10.1.1.3.
[3Com] router id 10.1.1.3

Description

packet. Using the undo silent-interface command, you can restore the default

You can use this command to disable an interface to transmit OSPF packet, so as
to prevent the router on some network from receiving the OSPF routing
information.
