Hi, we have 2 problems here that we can’t find the source.
we have a network running ospf/mpls/vpls. In the main router there are 30 VPLS interfaces. each interfaces have horiszon value set to 1. They are in the same bridge.
When i run torch tool on specific interface, sometime I can see traffic comming from other vpls interface. For no reason it appears for about 30 sec and disapear. It looks like horizon value dont work properly and vpls interfaces are leaking.
Also maybe the same problem source.
rt1 to rt2 = /29
rt2 to rt3 = /29
and so…
if i launch a ping from rt1 to rt3 there is no packets lost. That mean that the physical link is good. But if I ping a remote device wich is a part of the remote network (through the VPLS), we have a lot of packets lost ±10%.
any idea where i could search?
Maybe it’s VPLS management signaling packets? You should dump this and watch in a wireshark. Also, check all interfaces have the same horizon value. And make sure you have latest ROS version.
yes they have the same horizon value. All set to 1.
routeros and routerboard == 6.4.2 yes
i’m not familiar with wireshark but i can try.

If they are in same l2 domain, you can try to ping host in different VPLS. Dump it and see what you got.
I dcided to creat an other post for the second problem.
not working. I cant ping from different VPLS interface.
Means horizon rule works 
It’s just ldp signaling traffic you see.
mmm, not sure,
for exemple
scr: 10.10.10.100 (cpe of an other vpls)
dst: 66.75.26.58 (internet address)
I also noticed that:
when I run Torch tool to specific VPLS interface I can see traffic comming from an other VPLS interface to dst internet side like I explain before. One other thing that I found today is that RX is always 0 bps but Tx is higher (+512 bps).
