ASR1001 VPLS Issue

Question

Hello,
I am testing VPLS service on the ASR1001. I have three of them directly connected in a full mesh with autodiscovery mode. On the first two ASR1K I have a switch connected in order to test the end-to-end reachability.
The VCs are in UP state, ICMP, SSH (unicast) is OK between the switch but multicast traffic is blocked.
Here are the relevant configuration sections:
l2 vfi VPLS-123 autodiscovery
vpn id 123
bridge-domain 123
router bgp 123
bgp log-neighbor-changes
bgp update-delay 1
no bgp default ipv4-unicast
neighbor 2.2.2.2 remote-as 123
neighbor 2.2.2.2 update-source Loopback0
neighbor 3.3.3.3 remote-as 123
neighbor 3.3.3.3 update-source Loopback0
address-family ipv4
exit-address-family
address-family l2vpn vpls
  neighbor 2.2.2.2 activate
  neighbor 2.2.2.2 send-community extended
  neighbor 3.3.3.3 activate
  neighbor 3.3.3.3 send-community extended
exit-address-family
Interface facing to the switch (CE)
interface GigabitEthernet0/0/3
no ip address
negotiation auto
service instance 123 ethernet
  encapsulation default
  bridge-domain 123
Thank you for your help!

Hi Youssef,
What's IOS code which you are running? Seems like you are hitting DDTS CSCtz10928
fix of CSCtz10928 may be required to pass multicast traffic through vpls
You will need to upgrade your IOS to IOS-XE 3.7, which is 152-4S.
