[j-nsp] MPLS issue

[Ying Zhang]

Hello,

we are having a wired MPLS problem. Here is how the network looks like:

end users ---- M7i ---- M120 ----ISP

The mpls lsp is between M7i and M120. The problem is the end users have problems accessing certain websites, very slow or not accessible, some websites no problem at all. With MPLS disabled (OSPF only), the problem is gone. I think it is a MTU issue, tried to lower MTU on M7i user side, didn't fix it. Might also try to increase MTU  on MPLS interfaces, but not sure. Any thoughts? Very appreciated.
