Hi, Yes, this is because the 'domain-vpn-tag 0'. The other thing that it is doing is to zeroes the tag.
What type of routing-instance you are using on the CE? To not have the check on the CE you can use 'routing-instance type virtual-router' instead of 'routing-instance type vrf' Then you will not need 'domain-vpn-tag 0'.
