OmniSwitch AOS Release 6 Network Configuration Guide

IP is enabled on the switch by default and there are few options that can, or need to be, configured. This 
section provides instructions for some basic IP configuration options.

By default, the router primary address is derived from the first IP interface that becomes operational on the 
router.

 

The router primary IP address is used by BGP to derive its unique BGP Identifier, if the router

router-id is not a valid IP unicast address.

Use the

command to configure the router primary address.

 

Enter the 

command, followed by the IP address.

 

For example, to configure a router primary address of 172.22.2.115, 

you would enter:

-> ip router primary-address 172.22.2.115

By default, the router primary address of the router is used as the router ID. However, if a primary address 
has not been explicitly configured, the router ID defaults to the address of the first IP interface that 
becomes operational.

Use the

command to configure the router ID.

 

Enter the command, followed by the IP 

address. For example, to configure a router ID of 172.22.2.115, you would enter:

-> ip router router-id 172.22.2.115

By default, the route preference of a router is in this order: local, static, OSPF, RIP, EBGP, and IBGP 
(highest to lowest).

Use the 

 command to change the route preference value of a router. For example, to config-

ure the route preference of an OSPF route, you would enter:

-> ip route-pref ospf 15

To display the current route preference configuration, use the 

-> show ip route-pref
