I?m trying to establish a point to point MPLS VPN between 2 Metro 3750 switches
Both switches has the exact same basic config and all looks fine, ISIS is up, BGP is up, LDP is up.
All routes are where they are supposed to be as are all the lables. If I configure
a loopback i each of the boxes in the same vrf they are not able to ping each other.
If I take one of the Metro 3750 and move the config from the other to a 6500 and
connect them all works just fine.
Is there any limitations in the Metro 3750 that could be the problem ?
If you do a debug ip icmp, do the pings arrive at the switch, showing the correct source address? Does this work going *through* the switches, rather than *to* the switches?
I don't have access to my lab at the moment. Later this week I can try. I honestly don't remember whether I tried going to/from the loopbacks. I have run MPLS VPN/MVPN/CSC etc. all successfully.
