Eigrp Topology

[parthrawat979]

I don't know how to solve task 6 and 7 simultaneously when we have to use two distribute list on a same interface. One for the access list on R2 and second for the prefix list on R2 towards R1. I need a solution ASAPRouting, EIGRRouting, EIGRPP

Hello,

Focus on the logic first. Identify from which router the route is learned and where to filter it, inbound or outbound.

- Use ACLs for Task 6 and prefix lists for Task 7.

Remember EIGRP allows only one distribute list per direction, so if you need both ACL and prefix list on the same interface, combine them in a route map.

Verify with show ip protocols and show ip eigrp topology.

ip prefix-list blk-r6-l4-l7 seq 5 deny 6.1.4.0/22
ip prefix-list blk-r6-l4-l7 seq 10 permit 0.0.0.0/0 le 32

access-list 1 permit 6.1.0.0 0.0.15.255
access-list 1 deny 45.1.1.0 0.0.0.3
access-list 1 permit any

route-map blk permit 10
match ip address 1

route-map blk permit 20
match ip address prefix-list blk-r6-l4-l7

router eigrp 12345

distribute-list route-map blk out FastEthernet0/0
this is the route map I have configured and it is fail to stop a single route towards R1
