Hi Ahsan,
A Catalyst 6500 and the ME 6500 are slightly different inside. The problem is with the Catalyst 6500: The feature you're trying to use requires you to set Gi2/2 as a switchport, you can then terminate your L3 using an SVI.

Cheers
Ross

Subject: [j-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.
Cisco 3550 switch1 vlan 1089(1.1.1.1/30)---trunk----->sub interface eompls vlan 1089(Cisco 6503)----->(ACX 4000)terminating tunnel on sub interface vlan 1089----->Cisco 3550 switch2-trunk-vlan 1089(1.1.1.2/30)
We are using bgp & ospf between Cisco 6503 & Juniper ACX 4000. 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.

Any one seen before this type of issue. It would be much appreciated if i get any help asap.
Is there any workaround if someone knows?
Thanks & Regards,
