L2VPN Bridge Group

[jon_panes24]

Hi,

What does a bridge-group do in l2vpn in IOS-XR?

Is there any difference with creating one bridge-group and defining multiple bridge domains under it VS. multiple bridge-groups with a single bridge domain in it.

Example:

l2vpn
 bridge group g1
   bridge-domain bd1
      interface te1/1
      interface te1/2
   !
   evi 100
   !
   bridge-domain bd2
     interface te1/3
     interface te1/4
   !
   evi 101

Compared to

l2vpn
 bridge group g1
   bridge-domain bd1
      interface te1/1
      interface te1/2
   !
   evi 100
   !

 bridge group g2
   bridge-domain bd2
     interface te1/3
     interface te1/4
   !
   evi 101

Hi Jon,

as far as I understand, a bridge group is just a logical grouping for ease of configuration, so probably you can put all services for a customer (or ther logical group of your choice) in a single bridge group.

I dont believe it has an impact on how traffic is handled by the router

hope this helps

I agree with Mark. The benefit of bridge groups with multiple domains is the ability to separate services for your customers.
