What is VRRP, and how does it work?
VRRP, or Virtual Router Redundancy Protocol, is a networking protocol that allows multiple routers to act as a single virtual router. This creates a redundant and highly available network infrastructure, ensuring seamless failover in the event of a router failure.
At its core, VRRP works by electing a virtual router master, which is responsible for forwarding packets on behalf of the group. The other routers in the group act as backups and monitor the master router’s status. If the master router fails, one of the backups will take over its responsibilities, maintaining uninterrupted connectivity.
VRRP achieves this failover capability by utilizing a virtual IP address shared among the routers in the group. This virtual IP address serves as the gateway for hosts on the network, allowing for transparent failover without the need for reconfiguration.
In the following sections, we will explore the benefits of implementing VRRP in your network infrastructure and discuss its key features and considerations. Stay tuned to learn more about how VRRP can enhance network resilience.
