Template:Networking rutx configuration examples vrrp configuration

From Teltonika Networks Wiki


The Virtual Router Redundancy Protocol (VRRP) is a computer networking protocol used for automatic default gateway selection for clients on a LAN network in case the main router (Master) becomes unavailable. Another VRRP router (Backup) then assumes the role of Master; thus backing up the connection.

This page contains a guide on how to configure VRRP on {{{name}}} routers. To see the manual page for VRRP, [[{{{name}}} VRRP|click here]].

Explanation The routers and the PC are connected to the same network ( via a switch. The purpose of the system is to provide an Internet connection for the PC via the the MASTER (RUT1) router and backup that connection via the BACKUP ((RUT2)) router in case the MASTER fails.

Below is alternate topology that does not contain a switch. The configuration is identical for both cases. However, while the topology above provides a connection backup in case of any type of failure, the topology below will only backup the connection if the MASTER router loses its connection but remains available inside the network (i.e., it will not backup the connection if the MASTER is, for example, powered off).
