Configuring FHRP - GLBP

In my previous blogtorial we saw how we can configure HSRP. One downfall for using HSRP is that you can only use one router at a time. What if you wanted to use both R1 and R4 for load-balancing and failover? This is where Gateway Load Balancing Protocol comes in. Note that GLBP is Cisco proprietary. 

Consider the simple topology below. 

Objectives:
  • Configure R1 and R4 in a GLBP group with authentication
  • Configure R1 to be Active Virtual Gateway (AVG) and R4 to be Active Virtual Forwarder (AVF)
Relevant configurations are posted below.
