IOS XRv Error: AToM Dynamic with mismatched AC config

sheeptest
Level 1
Level 1

Hi,

I'm running IOS XRv in VMware Workstation. I have a simple topology of two PE routers connected to a P router, all running XRv.

I have configured Layer 3 VPN's and layer 2 Local E-Line VPN's (AC's on same PE) between the PEs with no problem. But when I try to configure a Layer 2 EoMPLS VPN over a pseudowire I get the following error:

Error: AToM Dynamic with mismatched AC config

 

Here's the full show output:

Any help would be greatly appreciated

"encapsulation dot1q <number>" is the command to use. I'm not sure where did the "dot1q vlan 100"sneak in from. XRv9k emulates an ASR9k, you can/should configure features in the same way as they are configured on ASR9k.

thanks. dot1q vlan xx did the trick under the subinterface.
