Same BGP ASN between CE and PE on both sides? By default BGP will reject this since it's own ASN is in the AS-PATH. This is BGP loop prevention mechanism. You will need to override this for it to work. router bgp 1 address-family ipv4 vrf xyz neighbor x.x.x.x as-override Without seeing your configs we are all just guessing here. Can you please post the relevant CE and PE configs from both sides?
