Where did you enable MPLS please, only in the core or on the edges as well? In other words are some ingress PEs and egress PEs running MPLS VPNs or just pure IP?
If only subset of core routers are running MPLS (allocates labels for NHs resulting in single label in the stack) then this should work. Just make sure the Vl2004 is not enabled for MPLS (expecting NH label) which I guess is true when the locally originated traffic is not affected. It appears as yet another HW programming issue with ME that no one stumbled across, cause to be fair these days it's all or nothing with regards to enabling MPLS in the core (greenfield deployments avoiding running into weired shituations). adam Adam Vitkovsky IP Engineer T: 0333 006 5936 E: adam.vitkov...@gamma.co.uk W: www.gamma.co.uk This is an email from Gamma Telecom Ltd, trading as “Gamma”.

I have a cisco tac case opened for the situation where Cisco ME3600X has balanced path and is dropping traffic. - in the balanced path One path is a label switched path and the other is non label switched. Traffic is dropped by the ME3600X when trying to push a packet it received with a label out the non label switched path. It only impacts traffic it receives traffic with a label, it does not impact traffic the router generates. this impacts all the IOSs available for the ME3600X.
