5. Select the Save link at the bottom of the dialog. Select Yes when prompted to save the configuration change
to the startup-config file on the device’s flash memory.
Changing the Router ID
The OSPF and BGP4 protocols use router IDs to identify the routers that are running the protocols. A router ID is
a valid, unique IP address and sometimes is an IP address configured on the router. The router ID cannot be an
IP address in use by another device.
By default, the router ID on a Foundry Layer 3 Switch is one of the following:
• If the router has loopback interfaces, the default router ID is the IP address configured on the lowest
numbered loopback interface configured on the Layer 3 Switch. For example, if you configure loopback
interfaces 1, 2, and 3 as follows, the default router ID is 9.9.9.9/24:
• Loopback interface 1, 9.9.9.9/24
• Loopback interface 2, 4.4.4.4/24
• Loopback interface 3, 1.1.1.1/24
• If the device does not have any loopback interfaces, the default router ID is the lowest numbered IP interface
configured on the device, as in earlier software releases.
NOTE: Foundry Layer 3 Switches use the same router ID for both OSPF and BGP4. If the router is already
configured for OSPF, you may want to use the router ID that is already in use on the router rather than set a new
one. To display the router ID, enter the
show ip CLI command at any CLI level or select the IP->General links
from the Configure tree in the Web management interface.
USING THE CLI
To change the router ID, enter a command such as the following:
BigIron(config)# ip router-id 209.157.22.26
Syntax: ip router-id <ip-addr>
The <ip-addr> can be any valid, unique IP address.
NOTE: You can specify an IP address used for an interface on the Foundry Layer 3 Switch, but do not specify an
IP address in use by another device.
USING THE WEB MANAGEMENT INTERFACE
1. Log on to the device using a valid user name and password for read-write access. The System configuration
panel is displayed.
2. Click on the plus sign next to Configure in the tree view to expand the list of configuration options.
3. Click on the plus sign next to IP in the tree view to expand the list of IP option links.
4. Click on the General link to display the IP configuration panel.
5. Edit the value in the Router ID field. Specify a valid IP address that is not in use on another device in the
network.
6. Click the Apply button to save the change to the device’s running-config file.
7. Select the Save link at the bottom of the dialog. Select Yes when prompted to save the configuration change
to the startup-config file on the device’s flash memory.
