My customer is facing a issue in load balancing OSPF in Multilink (Point to Point ) after configuring the multilink customer is only able to use 60 % of the bandwidth.
Now customer has removed the multilink but still he is not able to load balance ..
Customer requirement OSPF load balancing has to be optimized. Right now per-packet CEF is being used. But full bandwidth is not getting utilized.
I am attaching the multilink configuration which we tried and failed (only one multilink is coming up at a time, out of two). Please go through it and suggest any changes would be required.
Also we tried for per-destination CEF, but it was working fine, till we noticed that certain links are getting highly utilized at times(due to certain high bandwidth consuming application servers-hosts pairs are getting mapped to those interfaces ) and hence we went for per-packet CEF. Its working fine, still utilization is not optimized fully.(only 20-30%) of the bandwidth of each link is getting utilized).
We use a Cisco 2811 router with IOS version of 12.4(3f), and it supports fast switching functionality needed for per-destination CEF.
