GLBP Load balancing and weighting

[l.stafford]

Hi,

I have a requirement to load balance my host/server default gateway traffic on my network so that it exits the LAN via two seperate WAN links on seperate routers and utilises both connections. However 1 router has a 4Mb connection and the other router is a lower spec model with a 2Mb connection.

I want to configure GLBP to send 66% of the connections through one virtual forwarder (4Mb link) and the remaining 34% via the secondary active forwarder (2Mb link). The command glbp load-balance weighted seems to imply this can be achieved but does not seem to be configurable. Can GLBP be configured to share the connections in this way?

Thanks for any help offered.

Lee,

First you have to specify, the load balancing method as weighted.

glbp load-balancing weighted

The following commands will specify the weights and also enable the track feature.

glbp group weighting maximum [lower lower] [upper upper]

glbp group weighting track object-number [decrement value]

More details can be found here.
