Glbp load balancing

Unanswered Question
Aug 27th, 2008

I have issue in doing load balancing in GLBP, after configuring any GLBP load balancing mechanism latency of ip packet increases, some performance issues are there. some time packet will also discard due to high congestion on one router's serial interface. I mean to say load on one router out to two will increase. Any suggestion for this

I have this problem too.

Hello Sumit,

be aware that GLBP provides host based load sharing by answering client ARP requests for the VIP address with the MAC addresses of forwarders.

So you cannot expect a smooth load-balancing if you have few hosts producing a lot of traffic they can be served most by one router and so the effects you see.

Hope to help

Thanx Giuseppe

Well it quiet right that GLBP provides host based load sharing, but the problem is i have tried all glbp load balancing method but there will be no effect on problem. But in the same network if i run HSRP instead of GLBP it will work fine.
