Deciding between HSRP vs. VRRP vs. GLBP is a common challenge for network engineers. The right choice often depends on your network equipment, design goals, and specific redundancy requirements. All three are First Hop Redundancy Protocols (FHRPs) that operate at…
A comprehensive guide to understanding and configuring Virtual Router Redundancy Protocol (VRRP) on modern Cisco devices. Learn about VRRPv3, key concepts like priority and preemption, object tracking, and best practices for IPv4 and IPv6 environments.
HSRP is an FHRP (First Hop Redundancy Protocol) developed by Cisco to provide redundancy and high network availability almost anywhere in the network where we have two layer3 devices. HSRP config gives a group of routers a virtual IP address…
GLBP stands for Gateway Load Balancing Protocol and it is a Cisco proprietary First Hop Redundancy Protocol that attempts to overcome the limitations of existing redundant router protocols by adding basic load balancing functionality. In addition, it allows one virtual router…
