VRRP: Tune Advertisements to 3 Seconds
Advanced CCNP VRRP lab: standardize the VRRP advertisement interval to 3 seconds on a shared user VLAN. Two IOS routers (R1, R2) and two hosts connect to a single access switch on VLAN 10 (10.0.10.0/24). Both routers share VRRP group 1 and the same virtual IP 10.0.10.254 so hosts keep one default gateway. R1 is the master via priority 110; both routers explicitly set 'vrrp 1 timers advertise 3' to enforce a consistent master advertisement rate and backup master-down detection window. Verify with 'show vrrp' (Advertisement interval 3.000 sec) and host pings to the VIP.
