[j-nsp] L2VPN debugging...

[Hoogen]

Hi Nilesh,

I do have that configuration on all routers. I actually do have another
L3VPN configured between the same routers R4 and R6 which is working fine..

Hi Aditya,

Yeah I was trying to see all the traces I can get by turning on and off the
vpnc instance. But I couldn't comprehend why the vpn doesn't come up.. To me
it looks like the control plane is up but the data plane is down...:(

lab at r4# run show l2vpn connections
Layer-2 VPN connections:

Legend for connection status (St)
EI -- encapsulation invalid      NC -- interface encapsulation not
CCC/TCC/VPLS
EM -- encapsulation mismatch     WE -- interface and instance encaps not
same
VC-Dn -- Virtual circuit down    NP -- interface hardware not present
CM -- control-word mismatch      -> -- only outbound connection is up
CN -- circuit not provisioned    <- -- only inbound connection is up
OR -- out of range               Up -- operational
OL -- no outgoing label          Dn -- down
LD -- local site signaled down   CF -- call admission control failure
RD -- remote site signaled down  SC -- local and remote site ID collision
LN -- local site not designated  LM -- local site ID not minimum designated
