Hi, My full scenario
CE1 -------> PE1 -----------> PE2 -------------> CEZ On the PE1 interface I have a tunnel to CEZ . nb: PE2 is not mpls enabled. CEZ has a ptp link to PE2 LSP - tunnel is up from PE1---> CEZ and I can reach the CEZ router via the tunnel ptp. - from the CEZ lan CE1 lan is reacheable. It is only from the CE1 router and from the PE1 that I cannot reach CEZ lan. Please note this customer has 6 other branches which are working well.
