Hello,
I'm need help with following configuration, but can't figure it out myself:
Existing config:
int te0/1
service instance 44 ethernet
encapsulation dot1q 231,431,731
l2protocol forward cdp stp
bridge-domain 44
service instance 58 ethernet
encapsulation dot1q 246,446,746,2806
l2protocol forward cdp stp
bridge-domain 58
int te0/2
service instance 44 ethernet
encapsulation dot1q 1429 <- S-Vlan. Can't be changed.
rewrite ingress tag pop 1 symmetric
l2protocol forward cdp stp
bridge-domain 44
service instance 58 ethernet
encapsulation dot1q 1445 <- S-Vlan. Can't be changed.
rewrite ingress tag pop 1 symmetric
l2protocol forward cdp stp
bridge-domain 58
I'm need to add vlan 2806 to both sites.
Many thanks.

Hi Akash,
I'm really don't understand how to brifge it. I'm tried this config, but it not working.
Also, i'm unable to use xconnect on this 3700 switch.

may be image does not support mpls. Is LDP up and and running on that switch.
To add vlan 2806 you can configure
service instance 2806 ethernet
encapsulation dot1q 2806 >>>>> based on this tagged traffic with vlan 2806 will be processed by this service instance
rewrite ingress tag pop 1 symmetric >>> will pop tag while receiving traffic and add vlan tag while sending out
l2protocol forward cdp stp
bridge-domain 58 >>>> making it part of bridge-domain 58

Thank you, Akash,
It is not 3700, but 3560 switch. I think this model do not support xconnect at all.
I'm understand this part of config, bu hou you make it part of domain 44 also?
It is impossible to create one more instance with the same vlan 2806 to bridge it with domain 44.

What could be requirement of making one vlan part of two bridge-domain? You can make two vlan part of same bridge-domain but not one vlan part of two bridge-domain.
Can you do this with traditional switching (access port and trunk port)?
