RE: Directing traffic based on BGP community in a mpls vpn

You don't need to match the extended community, you just apply the policy under the address-family vpnv4. It's the same as IPv4 Unicast BGP traffic engineering, it's just that the policy goes onto the VPNv4 routes instead of IPv4. If you need more detailed help post your sanitized config.

Subject: Directing traffic based on BGP community in a mpls vpn envirment

Hi All

We have a scanrio like this where we have two data centers that are advertising the default route into the MPLS/VPN network and wed like some PE-routers to prefer Data Center 1, while the others should prefer Data Center 2 (and all PE-routers have to receive both default routes for redundancy reasons).

Got some solution for this like to manipulate any bgp attribute(weight;local pref) by matching the ext. community attribute in a route-map but this manipulation needs to be done at vpnv4 level.Is there any other solution for this.

Thanks
Sunil
