Maya,

The mailing list is not a place to discuss vendor specific issues. Let's
take this off-line.

Thanks.

> 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.
