[asterisk-users] Asterisk on MPLS VPN

[mir shahnawaz]

Are you able to ping 172.16.0.1 from your router (which is connected
to MPLS Network). If not then you have to tell your MPLS router where
is 172.16.0.0 connected. Do you have access on this router? If you
copy paste config here that would be helpful. I suspect that your ping
request is reaching MPLS router but router does not have a route for
this network. If this router is on the other side of MPLS network then
it is possible that ping is blocked by your service provider to hide
intermediate nodes.
 I don't think that you need any tunneling protocol for this as it is
already taken care by your provider.
