hi! I'm not very clear about the pre-empt command usage in VRRP and HSRP.
In HSRP, can the pre-empt command be used in the active, standby and listening router? or just applicable on the active router?
In VRRP, i got this sample config from the ccnp bcmsn course book. I do not understand why they disable the pre-empt in the standby router. Anyone can explain on this? Thanks.
CatalystA(config)# interface vlan 50
CatalystA(config-if)# ip address 192.168.1.10 255.255.255.0
CatalystA(config-if)# vrrp 1 priority 200
CatalystA(config-if)# vrrp 1 ip 192.168.1.1
CatalystA(config-if)# vrrp 2 priority 100
CatalystA(config-if)# no vrrp 2 preempt
CatalystA(config-if)# vrrp 2 ip 192.168.1.2
CatalystB(config)# interface vlan 50
CatalystB(config-if)# ip address 192.168.1.11 255.255.255.0
CatalystB(config-if)# vrrp 1 priority 100
CatalystA(config-if)# no vrrp 1 preempt
CatalystB(config-if)# vrrp 1 ip 192.168.1.1
CatalystB(config-if)# vrrp 2 priority 200
CatalystB(config-if)# vrrp 2 ip 192.168.1.2
