Configuration Guide - IP Routing
Step 4 Configure RIP to filter the imported routes.
# Configure an ACL on Router B and set a rule to deny the packets with the source address being
192.168.4.0/24.
[RouterB] acl 2000
[RouterB-acl-basic-2000] rule deny source 192.168.4.0 0.0.0.255
[RouterB-acl-basic-2000] rule permit
[RouterB-acl-basic-2000] quit
# Filter out the route 192.168.4.0/24 imported from RIP 200 on Router B according to the ACL
rule.
[RouterB] rip 100
[RouterB-rip-100] filter-policy 2000 export
Step 5 Verify the configuration.
# Check the routing table of Router A after the filtering. The route to 192.168.4.0/24 does not
exist in the routing table. This means that the route is filtered out.
[RouterA] display ip routing-table
Route Flags: R - relay, D - download to fib
