www.dell.com | support.dell.com Table 51-1. Recommended VRRP Advertise Intervals Total VRRP Groups Between 1000 and 1200 Between 1200 and 1500 Recommended Advertise Interval Groups/Interface Z-Serie S-Serie Z-Serie S-Series s s s 7 seconds 7 100 100 seconds 8 seconds 8 120 120 seconds Note: The 1500 VRRP groups are supported in FTOS Release 6.3.1.0 and later. The recommendations in Table 51-1 may vary depending on various factors like ARP broadcasts, IP broadcasts, or STP before changing the advertisement interval. When the number of packets processed by RP2/CP/FP processor increases or decreases based on the dynamics of the network, the advertisement intervals in may increase or decrease accordingly. Note: Increasing the advertisement interval increases the VRRP Master dead interval, resulting in an increased failover time for Master/Backup election. Take extra caution when increasing the advertisement interval, as the increased dead interval may cause packets to be dropped during that switch-over time.
