here is my L2VPN config
l2vpn
bridge group vlans
bridge-domain vlan100
interface Bundle-Ether3
!
interface TenGigE0/0/2/2
!
interface TenGigE0/0/0/0/1.100
!
routed interface BVI100

HI TKarnani,
I have modified my config to the below... Now the Bundle Ethernet and BVI doesnt come up
!
interface Bundle-Ether2
mtu 9216
!
interface Bundle-Ether2.999 l2transport
encapsulation dot1q 100
rewrite ingress tag pop 1 symmetric
!
l2vpn
bridge group 999
bridge-domain BD999
interface Bundle-Ether2
!
routed interface BVI100
!
int Te0/0/0/30
Bundle id 2 mode active
Any ideas? I was expecting BVI and BE2 to come up once I have a member on BE2 (Te0/0/30) but it doesnt seem to work

can you provide more information, what is the device mode / version of code, how your network connected.
AC: Bundle-Ether3, state is unresolved - Looking at this error we are not able to figure out how this was configured and transport you using.
reference if you like to know more information as example :

BE3 is not significant. I just tried adding it, The interface that is important is nterface TenGigE0/0/0/0/1.100, this is not an NCS router, its a ASR9K
I am not sure what this error means
Error: Need at least 1 bridge port up
I thought as long as TenGige0/0/01.100 is up it should be good?
Thanks

did you add l2transport on the configuration of your attachment circuits?
11-05-2020 06:28 AM
I just have this
interface TenGigE0/0/0/1.100 l2transport
encapsulation dot1q 100
rewrite ingress tag pop 1 symmetric
11-05-2020 07:12 AM
is there a typo? in the config you have interface TenGigE0/0/0/0/1.100 << but you provided TenGigE0/0/0/1.100 << extra 0 in the bridge domain?
11-05-2020 07:42 AM
Yeah, I got it to work now, so now I can see BVI is up on both my ASK9k and NCS5500 but I am unable to ping the BVI addresses from one box to the other..
Also, how would I test this that vlan100 is being transported on this link?
thanks

BVI does not understand vlans. so we will need to ensure that this command is under both physical interfaces "rewrite ingress tag pop 1 symmetric"
i would clear counters on both sides.
perform a ping with timeout 0
then check show interface for each physical interface to ensure we are sending out / receiving.
Thanks

Hi Tkarnani,
I can't add that command on the physical interface since it has sub interfaces, I get the error below when I try it.
!!% Subinterface or Layer 2 configuration conflicts with existing configuration, or configuration in this commit: Cannot configure an interface as L2 when it has sub interfaces
!

Hi I was talking about the subinterfaces, not the main interfaces.
put "rewrite ingress tag pop 1 symmetric" on both sides
ping, check the counters on each interface to see if the pings are being sent out and received
Thanks
