You are describing something I ran into last week when I did some testing with Juniper ACX1100 and SRX300's, and a Cisco 7301 in our lab. I realize that the 7301 is a far cry from a 6500, but perhaps the anecdote will help.
A Cisco 7301 was our P router in the lab, and had LDP propagation problems when the Cisco was using dot1q interfaces to talk to the Junipers. Ie; EX2200 <-> Juniper SRX300 <-dot1q-> Cisco 7301 <-dot1q-> Juniper ACX1100 <-> EX2200 The only measurable symptom - other than the l2circuit didn't function - was that the LDP tables on the Junipers were not showing -any- labels from the Cisco. Moving the Cisco config to the parent interface, or the native/untagged interface solved that issue, but was not acceptable for our production environment. However - the exact same config using dot1q interfaces worked fine when I replaced the Cisco 7301 with a Cisco ASR920. I never got to the bottom of "why", nor did I investigate further as the 7301's are long EOS/EOL. Your l2circuit appears to be up however, whereas ours would not owing to the missing labels. The config snippets you provided look sane - to my tired eyes at least. Our ACX1100 was tested fine with both 16.1R3.10, and 12.3X54-D27.1, and were using OSPF martini - no BGP/Kompella. -----Original Message----- From: cisco-nsp [mailto:cisco-nsp-boun...@puck.nether.net] On Behalf Of Ahsan Rasheed Sent: December-01-16 4:13 PM To: cisco-nsp@puck.nether.net Subject: [c-nsp] Help needed regarding the Eompls tunnel in Juniper & Cisco Hi All, We are having some serious issue with one customer circuit.We are using eompls vlan based & we are unable to pass traffic over eompls (l2)tunnel between Cisco 3550 switches if we use specifically Cisco 6503 ,Cisco 6504 & 6506 etc. If we use Cisco switch 6524 instead of Cisco 6503 it is working. {(Cisco 3550 switch)--->(Cisco 6524)---->(Juniper ACX 4000)---->(Cisco 3550) }-->This setup is working.I am able to pass traffic end to end between Cisco 3550's. {(Cisco 3550 switch1)--->(Cisco 6503 or Cisco 6506))---->(Juniper ACX 4000)---->(Cisco 3550 switch2) }-->This setup is not working.

Vlan 1089 as svi we are using on Cisco 3550 switch1 and allowing vlan 1089 as trunk connecting back to Cisco 6503,eompls vlan 1089 tunnel is configured on sub int on 6503 facing Cisco 3550 switch 1.Cisco 6503 is connected with juniper ACX 4000 & running bgp & ospf between each other.On ACX 4000 juniper eompls vlan based tunnel is terminating on sub interface facing Cisco 3550 switch 2. With Sup720 I was unable to pass traffic over tunnels although l2 eompls tunnel 1089 is up on both (Cisco 6503 & Juniper). See below. Below are the outputs & commands which i was running.
