Objective: Configure a route filter at A (R1) that will prevent D (R4) from learning about subnet 172.16.10.0/24 D#sh ip route 172.16.0.0/24 is subnetted, 14 subnets C       172.16.252.0 is directly connected, FastEthernet0/0 R       172.16.253.0 [120/1] via 172.16.252.1, 00:00:13, FastEthernet0/0 R       172.16.254.0 [120/1] via 172.16.252.1, 00:00:13, FastEthernet0/0 R       172.16.251.0 [120/1] via 172.16.252.1, 00:00:13, FastEthernet0/0 R       172.16.8.0 … Continue reading Route filtering: EIGRP and RIP mixed protocol lab. →
