When more than one next hop is learned from the same source, the router uses an equal cost

multi path algorithm that performs load balancing between routes.

Routing table configuration

When you configure the routing table, you can:

• View information about the routing table

• Add entries to the routing table

• Delete entries from the routing table

Note:

To change an entry in the routing table, delete the entry and then add it as a new entry.

The routes in the routing table are static routes. They are never timed-out, and can only be

removed manually. If you delete the interface, all static routes on the interface are also

deleted.

A static route becomes inactive whenever the underlying Layer 2 interface is down, except for

permanent static routes. You can disable the interface manually using the ip admin-state

down command. For more information, see

Permanent static route on page 432. When the

underlying Layer 2 interface becomes active, the static route enters the routing table again.

You can monitor the status of non-permanent static routes by applying object tracking to the

route. Thus, if the track state is changed to down then the static route state is changed to

inactive, and if the track state is changed to up then the static route state is changed to active.

For more information on object tracking, see

Object tracking on page 282.

Static routes can be advertised by routing protocols, such as RIP and OSPF. For more

information, see Route redistribution on page 472. Static routes also support load-balancing

similar to OSPF.
