In a scenario using MP-BGP route-reflectors for VPNv4 routes it is important to add the command 'undo policy vpn-target' to the route reflector:

bgp 345

peer 10.0.1.3 as-number 345

peer 10.0.1.3 connect-interface LoopBack0

peer 10.0.1.4 as-number 345

peer 10.0.1.4 connect-interface LoopBack0

ipv4-family unicast

ipv4-family vpnv4

undo policy vpn-target

peer 10.0.1.3 enable

peer 10.0.1.3 reflect-client

peer 10.0.1.4 enable

peer 10.0.1.4 reflect-client

With the default behaviour the route reflector will drop (and not reflect) routes for any RT import-extcommunity is does not know.
