Hi all,
I'm facing an issue with traffic through l2circuit, no traffic is going on that circuit while is showing UP others l2circuit is working (pass traffic).
I have a bockbone with 13 juniper EX4550 running all 12.3R12-S7, ldp and rsvp all enable on mpls interfaces.
between EX4550 cg-sw1 and cg-sw1 a circuit is configure as below
cg-sw1#
set interfaces xe-0/0/10 description "L2L Customer A"
set interfaces xe-0/0/10 mtu 9216
set interfaces xe-0/0/10 encapsulation ethernet-ccc
set interfaces xe-0/0/10 unit 0 family ccc
set protocols l2circuit neighbor 192.168.200.6 interface xe-0/0/10.0 virtual-circuit-id 2006
cg-sw6#
set interfaces xe-0/0/2 description "L2L Customer A"
set interfaces xe-0/0/2 mtu 9216
set interfaces xe-0/0/2 encapsulation ethernet-ccc
set interfaces xe-0/0/2 unit 0 family ccc
set protocols l2circuit neighbor 192.168.200.1 interface xe-0/0/2.0 virtual-circuit-id 2006
The circuit is UP has below but not traffic is passed:
cg-sw1> show l2circuit connections neighbor 192.168.200.6 interface xe-0/0/10.0

What is very strange to me is, if I disable and enable port, traffic start going trough but, an other l2circuit stop forwarding traffic at the same time on the equipement traffic while is showing UP and all others continue to work.
I have done traceoptions under [protocols l2circuit] no trace collect as all l2circuit is showing UP, note that on juniper EX4550 I can't perform ping mpls (not support), do some one faced already this issue ? do you have an idea, who to troubleshoot well and solve this issue ?
I was thinking may be the issue is the PFE (Packet Forwarding Engine), I checked "show pfe route ip/mpls" all labels are exchange well.
Any suggestion will be wellcome.
Thank you.
