ASR9K MAC filter

[Mapxaa]

Hi All,

How to check whether L2VPN is forwarding MAC and L2 traffic on ASR9K.

My topology : BRAS <-> ASR9K <-> OLTs   

In my case, ASR9K has learnt a mac from OLT but BRAS couldn't receive any traffic and MAC from ASR9K. 

l2vpn bridge group 3400 bridge-domain 3400
mac
  limit 
    maximum 128000

interface Bundle-Ether7.3401   <--OLT interface
split-horizon group

!
interface Bundle-Ether201.3400    <-- BRAS interface
!

I need to confirm whether ASR9K forward MAC or not?

Thanks.

Hello,

As far as i have understood. Packets coming to ASR9k on BE7.3401 and should be sent as Unknown unicast to BE201.3400.

You can try putting egress ethernet-services ACL on egress interface filtering for your MAC in question to see if that is leaving the router:

Also command

show l2vpn forwarding bridge-domain 3400:3400 hardware ingress detail loc <>

should show you the rate of traffic on each corresponding AC interface to see if l2vpn packets are exchanged correctly within BD.
