I can't for the life of me figure this out. I have two CCR routers running OSPF/MPLS/VPLS between them.
There is traffic flowing between them from two different VPLS tunnels. Occasionally, as shown in the graph, just one of them (same one every time) will throttle to 35Mbps download. Sometimes it recovers on its own after a few minutes, or over an hour. IF I go into the CCR INSIDE that tunnel (IP addresses inside the tunnel on both sides) and start a TCP bandwidth test between them, I get 900+Mbps and it magically fixes the problem every time. The only difference between the two tunnels I can tell, is the problem one is routing a block to an end router outside the tunnel on that port with a connected IP, and the other is a direct block routing to gateway on the edge CCR. Explain that one to me!
