13-76 Matrix E1 Series (1G58x-09 and 1H582-xx) Configuration Guide
13.1.5 Configuring VRRP
Purpose
To enable and configure the Virtual Router Redundancy Protocol (VRRP). This protocol eliminates
the single point of failure inherent in the static default routed environment by transferring the
responsibility from one router to another if the original router goes down. VRRP-enabled routers
decide who will become master and who will become backup in the event the master fails.
Commands
The commands needed to enable and configure VRRP are listed below and described in the
associated section as shown:
•router vrrp (Section 13.1.5.1)
•create (Section 13.1.5.2)
•address (Section 13.1.5.3)
•priority (Section 13.1.5.4)
•advertise-interval (Section 13.1.5.5)
•critical-ip (Section 13.1.5.6)
•preempt (Section 13.1.5.7)
•enable (Section 13.1.5.8)
•ip vrrp authentication-key (Section 13.1.5.9)
•ip vrrp message-digest-key (Section 13.1.5.10)
•show ip vrrp (Section 13.1.5.11)
13.1.5.1 router vrrp
Use this command to enable or disable VRRP configuration mode.
router vrrp
NOTE: You must execute the router vrrp command to enable the protocol before
completing other VRRP-specific configuration tasks. For details on enabling
configuration modes, refer to Tabl e 3- 1 0 in Section 3.3.3.
