EoMPLS L2VPN VPLS delivering double tags

Wed Apr 29, 2020 2:57 pm

Hello

Im running RouterOS 6.46. I have configured VPLS cisco-style betwen PE2 and PE3 as such

CE2 (tag 1003)----[PE2 mikrotik]------[P]------[PE3 juniper]----(tag 1003)CE3

The VPLS is up but the problem is when I ping from CE2 to CE3 and vice versa the ping fails.

After packet capture analysis when ping from CE2 to CE3 I have seen:
1. Packets from CE2 towards PE2 are tagged with 1003 (this is expected)
2. Packets from PE3 towards CE3 are sent out with no vlan tags (this is not expected)

After packet capture analysis when ping from CE3 to CE2 I have seen:
1. Packets from CE3 towards PE3 are tagged with 1003 (this is expected)
2. Packets from PE2 towards CE2 are having double tags of 1003

Kindly review and advise what can be done to fix this

Configuration on PE2
/interface bridge
add name=VPWS-1003

/interface vlan
add name="VPWS-1003 SERVICE END TO CE2" interface=ether2 vlan-id=1003

/interface vpls
add name="VPWS-1003 ENDOINT JUNIPER PE3" cisco-style=yes cisco-style-id=1003 pw-type=tagged-ethernet remote-peer=10.10.10.3 disabled=no

/interface bridge port
add bridge=VPWS-1003 interface="VPWS-1003 SERVICE END TO CE2"
add bridge=VPWS-1003 interface="VPWS-1003 ENDOINT JUNIPER PE3"
