Qinq over atom not working

I am trying to establish qinq over atom between 2 ASR-1001x running mpls in between. Everything comes up after configuration but I am not able to ping each other. At the same time layer2 mpls- atom with single vlan is working fine.

 

    Instead of testing with host , we are using switches with Vlan interfaces for ping test. Swicthes are connected with trunk to routers

 

Please find the below configuration

 

Router A

 

interface GigabitEthernet0/0/3.740
 description test
 encapsulation dot1Q 740 second-dot1q 741

!
interface pseudowire740
 encapsulation mpls
 neighbor 172.21.159.1 740

 

l2vpn xconnect context QIIND
 member pseudowire740
 member GigabitEthernet0/0/3.740

 

SWITCH A

 

interface Vlan741
 ip address 10.1.1.2 255.255.255.0

 

 

ROUTER B


i
nterface GigabitEthernet0/0/3.740
 description test
 encapsulation dot1Q 740 second-dot1q 741

!
interface pseudowire740
 encapsulation mpls
 neighbor 172.21.143.254 740

 

!
l2vpn xconnect context QIIND
 member pseudowire740
 member GigabitEthernet0/0/3.740

 

Switch-B

interface Vlan741
 ip address 10.1.1.1 255.255.255.0

 

 

Please fins the below show commands

ROUTER A

 

SH MPLs L2transport Vc

   Local intf     Local circuit              Dest address    VC ID      Status

Gi0/0/3.740    Eth VLAN 740/741           172.21.159.1    740        UP

 I would like to add couple of more thing. The MTU of the path in between is 1500 and there are some hardware in the path which doesn't support qinq .

 

 Does it make any issue ?
