[c-nsp] ASR920 vlan pass through

[John Gaffney]

Then on that note I would google up layer 2 MPLS protocols for the ASR (it's basically layer 2 over layer 3, allows you to route layer 2 traffic) or look at making a dot1q tunnel. Google should have config examples and specifics for that router type. Depending on your goals you may need to combine both to make your solution work.

Or if your lucky somebody else on the list can comment on your type of router, and give you a config snip.

Thanks,

Yes we want to maintain layer 2 straight through basically like a catalyst switch would pass the layer 2 between ports.

I am assuming that you want the traffic to stay layer 2? That is no routing of the VLAN?

Sounds to me like you need either layer2 MPLS (EoMPLS) or maybe just a dot1q tunnel port. Not sure about what would work better for a 920, but I would start looking at those two rather than do bridge domains.

Forgive the simplicity of this question but I haven't found any literature to convince me.

Is this the only or best way to "pass" vlans through the ASR920? We have a circuit coming in with multiple vlans in no order and want to send them out another interface without modification.

interface GigabitEthernet0/0/5
no ip address
negotiation auto
service instance 1 ethernet
  encapsulation dot1q 10,20,30,40
  bridge-domain 1

interface GigabitEthernet0/0/7
description Uplink to pod01-esw01
no ip address
negotiation auto
service instance 1 ethernet
  encapsulation dot1q 10,20,30,40
  bridge-domain 1

Thanks,

Greg
