Improvement at the gateway level is now more than just about redundancy as we can use Cisco’s sophisticated feature called GLBP or Gateway Load Balancing Protocol. Just by looking at the name, we can easily guess its superior value compared to HSRP or VRRP. In HSRP or VRRP, only the active/master router that do the […]
VRRP or Virtual Router Redundancy Protocol is the open standard version of Cisco’s HSRP. It is also used to provide redundancy of a gateway by using multiple routers, but since it’s an open standard then it can be implemented using routers from vendors other than Cisco. Most of VRRP logic are very similar to HSRP, […]
HSRP or Hot-Standby Routing Protocol is a mechanism developed by Cisco to add redundancy at the gateway of a subnet. The idea of HSRP is using multiple routers to serve as a gateway using one virtual IP address. One of the routers will be designated as the active gateway, and if it’s become unreachable there […]
