IP Configuration
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.
Configuring the Router Primary Address
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
ip router primary-address
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
Configuring the Router ID
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
ip router router-id
address. For example, to configure a router ID of 172.22.2.115, you would enter:
-> ip router router-id 172.22.2.115
Configuring the Route Preference of a Router
By default, the route preference of a router is in this order: local, static, OSPF, RIP, EBGP, and IBGP
(highest to lowest).
Use the
ip route-pref
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
