Cisco7609(PE,GE-WAN port,Fa8/29)---(Ethernet to E1 convertor)---ISP lease line(E1)---(E1 to Ethernet convertor)---Cisco1721(CE)
Only one of four customer sites connected to this PE is strange:
On PE,I can receive the rip routes send by this site(we can call it Site-D),and other vpn sites(Site-A,B,C) can ping site-D with the destination ip address is the segment between PE and Site-D router and the PE can do it too,but almost 70% packets lost.If I plug off the UTP5 cable which connected to Site-D from PE and plug it to a PC,no packet lost.
So I think no MPLS configuration error on PE and Site-D,it a packet lost problem.
On PE,I found error message:
%PM_SCP-SP-4-LCP_FW_ABLC: Late collision message from module 8, port 032
%PM_SCP-SP-4-LCP_FW_ABLC: Late collision message from module 8, port 036
