stop advertising 192.168.3.0/24 route using a distribute list and ACL.

[husqvarna1990]

Hello i am struggling to figure out how i can implement a distribute-list and ACL on a router to stop advertising a route 192.168.3.0/24, the issue is i am using OSPFv3 address-family and EIGRP named instance. 

In what mode must i apply the distribution-list as all the Cisco examples i have read use OSPFv1 to which my OSPFv3 and named EIGRP has no distribute list that i can find and i am using 15.2 ISO image as required?

Hello,

in EIGRP, you have to get into address family mode and then into topology base mode to use the distribute list,e.g.:

R1#conf t
R1(config)#router eigrp HOME
R1(config-router)#address-family ipv4 unicast autonomous-system 1
R1(config-router-af)#topology base
R1(config-router-af-topology)#distribute-list

In OSPFv3 you also need to be in address family mode, although I think you need version 16.5:

R1(config)#router ospfv3 1
R1(config-router)#address-family ipv4 unicast
R1(config-router-af)#distribute-list route-map rmap-name in

If I understood you correctly, the following would be the way to accomplish this:

   

Hope this helps.
