Blocking Routing Updates on an Interface

The interfaces on the switch receive routing updates every 30 seconds,
including the interfaces that are not connected to routing devices. To
prevent the switch from sending out routing updates to an interface, which
does not need routing updates, use the PASSIVE-INTERFACE command
on the interface. This command still allows the network in the interface to
be advertised to other routing devices.

The following example advertises the VLAN 20, but blocks the switch from
sending routing updates to VLAN 20:

awplus> enable
awplus# configure terminal
awplus(config)# router rip
awplus(config-router)# network vlan20
awplus(config-router)# passive-interface vlan20
