Sikandar,
Adam is right. Reason being IP needs untagged frame for processing.
Best Regards,

Subject: Re: [c-nsp] Management VLAN and Bridge Domain on ME3600 Switch

Hi Adam
Thanks for the reply. It's much appreciated.

Just few questions:

1. As you can see from my config I am doing double tagging as well but 
difference is you are doing pop2 instead of pop1.I just would like to ask what 
would be the benefit of doing pop2 on the port facing service provider?

2. I tried configuring exactly the same configuration for management VLAN as 
well but again the difference was I didn't do pop2. I am bit puzzled why it 
didn't work with pop1 which is essentially taking the outer tag off and IP 
address is configured on the second VLAN so in theory it should work

I will give it a go to your config and get back to you.

Many Thanks

Sikandar

Hi Ali,
First of all I'd try to get a L2 transparent circuit from the provider not just 
a single VLAN -might be available at the same price.
If that's not an option than I'd try to double tag the frames on the uplink to 
the provider as follows:
(Please check whether there's enough MTU on the uplink)
interface GigabitEthernet0/13
mtu 1512
service instance 25 ethernet
  descript transport customer1
  encapsulation dot1q 100 second-dot1q 10
  rewrite ingress tag pop 2 symmetric
  bridge-domain 25
!
service instance 20 ethernet
  descript management
  encapsulation dot1q 100 second-dot1q 20
  rewrite ingress tag pop 2 symmetric
  bridge-domain 20
interface vlan 20
descript switch management interface
vrf for mgmt
ip add 10.0.0.1 255.255.255.252
Interface GigabitEthernet0/19
port-type nni
switchport trunk allowed vlan none
switchport mode trunk
mtu 1504
service instance 26 ethernet
  descript to customer1
  encapsulation dot1q 200,433,472
  bridge-domain 25
