Dell Force10 E600i FTOS Version 8.4.1.5 Configuration Guide for ExaScale - Page 1044

www.dell.com | support.dell.com The recommendations in Table 60-1, "Recommended VRRP Advertise Intervals," in Virtual Router Redundancy Protocol (VRRP) 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. CAUTION: 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. VRRP version 3 VRRP version 3 defines VRRP for IPv6. The vrrp-ipv6-group command is used to create IPv6 VRRP groups, and is similar to the vrrp-group command, which creates an IPv4 VRRP group and moves you from INTERFACE mode to a group-specific VRRP command sub-mode. In the VRRP mode, all VRRP commands are supported for IPv4 and IPv6, except for authentication-type which is not supported for IPv6. Also, the following EXEC commands are different for IPv4 and IPv6: • clear: • IPv4: clear counters vrrp • IPv6: clear counters vrrp ipv6 • debug: • IPv4: debug vrrp • IPv6: debug vrrp ipv6 • show: • IPv4: show vrrp • IPv6: show vrrp ipv6 VRRP Configuration By default, VRRP is not configured. The following list specifies the configuration tasks for VRRP: • Create a Virtual Router (mandatory) • Assign Virtual IP addresses (mandatory) • Set VRRP Group (Virtual Router) Priority (optional) • Configure VRRP Authentication (optional) • Disable Preempt (optional) • Change the Advertisement interval (optional) • Track an Interface or Object (optional) For a complete listing of all commands related to VRRP, refer to FTOS Command Line Interface. 1044 | Virtual Router Redundancy Protocol (VRRP)
