Advanced Configuration and Management Guide
• 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: HP routing switches use the same router ID for both OSPF and BGP4. If the routing switch is already
configured for OSPF, you may want to use the router ID that is already in use on the routing switch 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:
HP9300(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 HP routing 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.
Setting the Local AS Number
The local AS number identifies the AS the HP BGP4 router is in. The AS number can be from 1 – 65535. There
is no default. AS numbers 64512 – 65535 are the well-known private BGP4 AS numbers and are not advertised
to the Internet community.
To set the local AS number, use either of the following methods.
USING THE CLI
To set the local AS number, enter commands such as the following:
HP9300(config)# router bgp
BGP4: Please configure ’local-as’ parameter in order to enable BGP4.
HP9300(config-bgp-router)# local-as 10
HP9300(config-bgp-router)# write memory
Syntax: [no] local-as <num>
The <num> parameter specifies the local AS number.
