How to terminate a vlan on ASR 9000 and bridge it to a port on asr 9000

we want to use the ASR to connect a client which has no vlan tag and add a vlan tag 100 on it when the traffic goes out from ASR to internet.


CLIENT --------- ASR ------TRUNK-------Internet PE


Here the configuration example:

!
interface GigabitEthernet0/0/0/0.100 l2transport
  encapsulation dot1q 100
  rewrite ingress tag pop 1 symmetric
!

!
interface GigabitEthernet0/0/0/1
  l2transport
!

!
l2vpn
!
bridge group cust1
  bridge-domain cust1
   interface GigabitEthernet0/0/0/0.100
   interface GigabitEthernet0/0/0/1
!  

• GigabitEthernet0/0/0/1 is the access port (untagged).
• interface GigabitEthernet0/0/0/0.100 accepts tagged frames with vlan 100.
• L2vpn bridge-domain cust1 connects both interfaces together.
• GigabitEthernet0/0/0/0.100 has tag rewrite operation. Removing tag on ingress, so sending untagged to GigabitEthernet0/0/0/1, and pushing tag 100 on egress, so untagged frames from gi0/0/0/1 got tagged

Google shows this question asked hundreds of times. There are many work-arounds and bug reports on this.
However it isn't a bug. It's a feature. The feature is intended to truncate unwanted signatures from Usenet (forum) posts. The signature is signified by a double hyphen and a space on a line by itself "-- ".
You can turn this feature off in Thunderbird's configuration by:

Advance -> Config Editor -> [I'll be careful] -> (search for) mail.strip_sig_on_reply -> [toggle it to false].

By the way, I spend about an hour searching for how to do this on every Thunderbird install. Hopefully this definitive answer will save Thunderbird users time.
