  1. Hey, what is the difference in using route-maps or access-lists or prefixlists when applied to distribute-list ? they all do the same in regards to filtering routes in ospf or eigrp ? are there any minor difference between those ? can you please explain in detail. Thank you.

  2. Hi Rene, I have a question regarding recusive routing and the filtering of routing interfaces.
    I have a network similar to the one shown in the EIGRP Route-MAP Filtering lesson. The difference I have in my network is that the Tunnel areas has two ASAs so that if the primary route fails routing information can be sent over a tunnel to the remote site via the internet. Routing on this network is provided bt EIGRP. Currently when the primary route fails the link that goes over the internet goes into recursive routing and fails.

    interface Tunnel0
     ip address 192.1

  3. Hi @Robhorseman101,

    The EIGRP route-map filtering lesson only has two routers with a single link so I think you had something else in mind? :smile:

    In your config, I see the tunnel interfaces of your routers:

    interface Tunnel0
     ip address 192.168.100.2 255.255.255.0
     tunnel source GigabitEthernet2/0.40
     tunnel destination 10.164.56.33
    

    And:

    interface Tunnel0
     ip address 192.168.100.1 255.255.255.0
     tunnel source GigabitEthernet2/0.40
     tunnel destination 10.164.58.33
    

    Not sure on which router you get the recursive routing error but for example, if it’s the first one th

  4. Hi Rene,

    I had a question on the Design and efficiency portion here.

    We can place access-list on “in” or “out” I looked up the following which says standard access list should be placed near destination.

    Standard Access Control List (ACL) filters the traffic based on source IP address. Therefore a Standard Access Control List (ACL) must be placed on the router which is near to the destination network/host where it is denied. If we place the Standard Access Control List (ACL) near to source of the traffic, there is a chance for denial or other legitimate tr

  5. Thanks for answering.

    So it seems to me that Best Practice here is just a starting point. Once you get enough knowledge you can be even more efficient depending on the specific design and setup. That was what I was really getting at. I am starting to understand it so my thinking once I have the basic grasp is not held down by specific rules because rules are for the most part general in nature.

    I just wanted to ask and confirm that before hand because while what I just stated is logical and common sense if your not careful and don’t ask questions there may b
