Can someone please explain what the redundancy keyword at the end of a
static nat statement does? For example:
Ip nat inside source static 10.1.123.1 192.1.1.1 redundancy HSRP-1
We tried the configuration from Narkbik's NAT lab excercise #9, and we
found that failover worked the same with or without the redundancy
keyword:
Ip nat inside source static 10.1.123.1 192.1.1.1
Here is the relevant configuration:
On R2
interface FastEthernet0/0
Standby 1 ip 10.1.123.100
Standby 1 priority 110
Standby 1 preempt
Standby 1 name HSRP-1
Standby 1 track FastEthernet0/1 50
ip nat inside
interface FastEthernet0/1
Standby 2 ip 200.1.1.100
Standby 2 priority 110
Standby 2 preempt
Standby 2 track FastEthernet0/0 50
ip nat outside
Ip nat inside source static 10.1.123.1 192.1.1.1 redundancy HSRP-1
On R3
Interface FastEthernet0/0
Standby 1 ip 10.1.123.100
Standby 1 preempt
Standby 1 name HSRP-1
ip nat inside
Interface FastEthernet0/1
Standby 2 ip 200.1.1.100
Standby 2 priority 100
Standby 2 preempt
ip nat outside
Ip nat inside source static 10.1.123.1 192.1.1.1 redundancy HSRP-1
