Hi to all.
I have lots of qinq channels to our remote sites. Channels are provided by our ISP by separate links from ISPs switch to our switch, without second tag (s-vlan). Now, we are going to migrate all our channels to one 10G interface, and provider will give us our channels with double tag (s-vlan + c-vlan).
All management interfaces on switches (SVIs) are in c-vlans. Regarding that i have a question: how can I globally configure sub interface for management (on Cisco ASR1004), for all c-vlans, from different s-vlans?
Here is attached topology, what will be after migrating to one 10G link with ISP.
P.S. Sorry for my terrible english :(
Solved! Go to Solution.

heh. i think this is not possible (symmetric) because how router would choose right first vlan tag for outgoing traffic?
so create service instance for each s-vlan and bridge it to BDI.

hello. try this.
interface TenGigabitEthernet1/1/0
no ip address
service instance 2215 ethernet
encapsulation dot1q any second-dot1q 20
rewrite ingress tag pop 2 symm
bridge-domain 2215
!
end
and then create interface bdi2215.

Hi! But there is no "encapsulation" command at all (((

Hi! I've upgraded IOS Software, and tried configure interface as proposed above, but no success ( Rewrite change is not logically valid on ServInst 2215(Gi1/1/0)), u cannot configure to poping out tags with range of s-vlans or c-vlans... only push
I've tried to push top and inner tags - also no success. Can't understand, what's wrong in my configuration?

does it affect to cpu utilization?
