Routing

Hello,

I am trying to make work a simple MVPN scheme, a topology picture is attached.  The sender is on the left with an ip 172.15.0.100 sending to group 239.1.2.3, sender site's PE stays in Pruned state despite all necessary conditions to forward:

Where could be the issue with this setup? 

Thanks in advance!

Ok, seems to be p2mp was missed in the ldp section of listeners' PE and P

root@Tokyo# run show multicast route instance Red extensive

    Source: 172.17.0.100/32

But no traffic is leaving the sender PE , maybe problem is related to VirtualBox environment ? 

I used iperf and its default packet size  - 1470 , so   increasing mtu on interfaces has allowed the traffic to flow
