  1. Thanks Rene - so am I right in thinking there is no implicit deny on a route map used as an export map in this process? Anything not matched on the route-map will just use the default settings configured.

    Normally when applying a route-map to a neighbour in IPv4 (e.g. neighbor X route-map Y) if something isn’t positively matched in the route-map, it will get dropped?

  2. Hi Chris,

    It still has the implicit deny but when you use a route-map as an export-map, it only tells the router which route-targets to add. When you use a route-map with a neighbor for a routing protocol, it works as a filter for routes.

    For example, this is the default route-target on PE1:

    ip vrf CUSTOMER
     rd 1:1
     route-target export 1:1:

    And we use this export-map:

    PE1(config)#ip prefix-list CE1_L0 permit
    PE1(config)#route-map EXPORT_MAP permit 10
    PE1(config-route-map)#match ip address prefix-list CE1_L0

    Then we end up with:

    PE1#show ip bgp vpnv
