Configuring Route Filtering
Network requirements
As shown in the following figure:
z
All the switches in the network run OSPF. The AS is divided into three areas.
z
Switch A and Switch B work as ABRs.
z
Configure Switch C as an ASBR to redistribute external routes (static routes), and configure a filter
policy on Switch C to filter out redistributed route 3.1.3.0/24.
z
Configure a route policy on Switch A to filter route 10.5.1.0/24.

2) Configure OSPF basic functions (Refer to
).
3) Configure OSPF to redistribute routes.
# On Switch C, configure a static route destined for network 3.1.1.0/24.
