  1. Hi Alfredo,

    Are your London and Italy sites only advertising their own prefixes?

    If you want your users from CE2 to be able to reach London in case CE-1 is down then you should advertise the prefixes from London from OSPF into BGP on Italy so that CE3 can learn them. You could use conditional advertising or use some of the BGP attributes so that this path is not preferred as long as CE-1 is up and running.

  2. Hi Davis,

    There’s a lot of things that could be wrong. Here’s a simple checklist you can use:

    Here’s what you should check and in what order:

    2. Make sure the VRF is created on both PE routers.

    3. Make sure you use the correct RD for each VRF.

    4. Make sure you have the correct import/export route-targets.

    5. Check if you see routes in the VRF routing table on the PE routers.

    6. Check if you have an IBGP neighbor adjacency between the PE route

  4. Hi Thomas,

    You will have to configure “hairpinning” on your ASA so that it translates traffic that arrived on its OUTSIDE interface and forwards it out of the same OUTSIDE interface again. Here is an example I created before for remote VPN users, your setup will be similar:

    Cisco ASA Hairpin Remote VPN users

    In your case, you don’t have remote VPN users but the idea is the same.
