Hi everyone!

we are have a problem with enabling vc on EoMPLS circuit on Cisco ME3600x. all configuration is the same and working, we are checked ping, traceroute, ping mpls ipv4, ping mpls pseudowire, every our trying was clear and well, but when we want to see a status of vc it is still Down. after i was entered the command "sh mpls l2 vc 1517 det"  after that we can see this

Hello mate !Please, paste

Hello mate !

Please, paste your configurations here.

 

The only thing that brings to my attention is this:   

 

"Last local AC  circuit status rcvd: DOWN AC(rx/tx faults)"

 

Have you checked the health of your local interface ?

hi
can you please tell me what kind of configuration you want to see?
and second, can you please explain to me which local interface i need to check?

"Local interface" - Interface

"Local interface" - Interface used as the attached circuit, the one towards the LAN

About the configuration, you can paste all things related to the vpls section

I never saw a L2VPN using a SVI....

 

Try to create a pseudowire-class on both sides, and use the loopback f both as source address for this connection (of course, if the loopbacks are reachable between each other)

somethink like... (i dont have a router to test it now)

 

pseudowire-class EoMPLS   
 encapsulation mpls
 ip local interface loopback 0 

 

 

Then dont forget to add the pseudowire class in the xconnect (both sides)

 

xconnect 10.70.1.2 1517 pw-class EoMPLS

when i configure pw-class i

error is still present (((

i think your and my old configuration is same right, but a problem does not bound with configuration EoMPLS, i think a location of problem  is ME3600x, because in statistic of VC detail we are can see sent packets from ASR901, and not sent any packets from ME36600x

yeah.. forget it, that

yeah.. forget it, that command is just for L2TPv3 (i forgot) ....

 

Try to make sure what is the best practice when using an interface vlan as the source, i never used it (maybe will lab it soon)

 

This status appears when the physical link is up/down or down/down, which is not your case !!

 

hope i could help

good luck

Hello MaratCould you try to

Hello Marat

Could you try to configure mpls ldp explicit-null on ASR901 side and see if that resolves the problem.

I would like to know what code are you running on both sides.

Please let me know if this helps.

Thanks

Were you able to resolve this

Were you able to resolve this issue?

This message "Last error: Local peer access circuit is down" can be due to LDP having an error processing the PW during creation.

Can you try removing the xconnect and put it back on ME3600 int vlan 1517 and if it doesn't work try to clear ldp adjacency(clear mpls ldp nei 10.70.2.66). 

 If clearing the LDP neighbor does not work, then please collect debugs below.

sh mpls l2 vc 1517 det
sh mpls l2 vc 1517 det
sh mpls l2 vc 1517 det

show mpls l2 vc 1517 detail.

there is additional error like this :

does it have correlation between (nmpls_next_label_check: Label allocation Failed) and (Local peer access circuit is down)

Re: L2VPN EoMPLS status down on ME3600x

It means something is wrong at the local interface.
