ARP entry issue on H-VPLS

Adam White

Howdy, 

 

So I have a small issue in my lab.

I have setup H-VPLS with BGP autodiscovery. 

All cicruits are up, everything seems great. 

Problem is I only get 1 way traffic. From Test_A, I see the mac address from Test_B. I dont see the other way round. 

However, in the bridge-domain on Test_B device, I see the mac address entry no problem.

 

U-PE has xconnect to PE_B. from there i have configured auto-discovery and this session goes to PE_A where the other IP address lives.
