Router 2921 (customer Side)

 

interface GigabitEthernet0/1.595
encapsulation dot1Q 595
ip address 172.16.59.2 255.255.255.252

Hello Freddy!

 

Can i ask why you are double tagging the traffic? Is the provider adding an SVLAN?

 

If this is the case your CE side looks ok but can you share the config of VLAN/BDI 2003 please ? 

 

The PE config looks like it needs some work.

 

Can you give this a try? This is how i would do it...

 

ASR903 (To MUX)

interface GigabitEthernet0/1/5

service instance (SVLAN) ethernet
encapsulation dot1q (SVLAN) second-dot1q 595

rewrite ingress tag pop 2 symmetric
bridge-domain 2003

!

Service instance 2003 ethernet

encapsulation dot1q (SVLAN) second-dot1q 1595

rewrite ingress tag pop 2 symmetric

bridge-domain 2003

!

 

If you're not using an SVLAN this would work.

 

service instance 1 ethernet
encapsulation dot1q 595
rewrite ingress tag pop 1 symmetric
bridge-domain 2003
!
service instance 2003 ethernet
encapsulation dot1q 1595
rewrite ingress tag pop 1 symmetric
bridge-domain 2003

!

END

 

Let me know how it goes, this is my first post :D
