VRRP with VSX configuration

VRRP is similar to active gateway in that it is a first hop redundancy protocol that eliminates a single point of failure. One VSX switch acts as a VRRP master and the other switch acts as the VRRP backup. Both VSX switches route the traffic. The active gateway/VRRP configuration must be consistent across the two VSX switches. The active gateway/VRRP are mutually exclusive configurations at the switch.


Active gateway is preferable to VRRP because VRRP traffic is still pushed over the ISL link, resulting in latency.

Sample VRRP configuration

switch# configure
switch(config)# vlan 1-10
switch(config)# router vrrp enable
switch(config)# interface vlan2
switch(config-if-vlan)# ip address
switch(config-if-vlan)# no shutdown
switch(config-if-vlan)# vrrp 1 address-family ipv4
switch(config-if-vrrp)# address primary
switch(config-if-vrrp)# no shutdown
switch(config-if-vrrp)# exit
switch(config-if-vlan)# exit
