> Hello all,
> Has anyone set up Mayer 2 tunnels over MPLS between a
> Juniper ERX and a Cisco 7206. I am trying it and having 
> difficulties. However, I had no trouble setting it up between 
> Cisco 7206s and between ERX virtual routers. The basic 
> problem seems to be that although the targeted LDP session is 
> up between the Cisco and the ERX, the LDP process at the ERX 
> end is not receiving the VC label from the Cisco. The Cisco 
> receives the VC label from the ERX alright. The base LSP 
> looks fine. Your suggestions are welcome.
