4) Configure an filtering policy to filter redistributed routes
# Define ACL 2000 and reference it to a filtering policy to filter routes redistributed from RIP 100 on
Switch B, making the route not advertised to Switch C.

Configuring an Additional Metric for a RIP Interface
Network requirements
As shown in the following figure:
z
RIP is enabled on all the interfaces of Switch A, Switch B, Switch C, Switch D, and Switch E. The
switches are interconnected through RIPv2.
z
Switch A has two links to Switch D. The link from Switch B to Switch D is more stable than that from
Switch C to Switch D. Configure an additional metric for RIP routes received through
VLAN-interface 200 on Switch A so that Switch A prefers the 1.1.5.0/24 network learned from
Switch B.
