Hi
thank you for reply. I have visited that site also. I did not understand
complete example. For example 10.88.194.17 and 10.88.194.18 is physical
interface address or HSRP address is not clear. Under "ip nat Stateful id
2" below both address is 10.88.194.17. That does not make sense. Do have
any idea?

Configuration Examples for SNAT

This section provides the following configuration example:

Configuring SNAT with HSRP

Configuring SNAT Primary/Backup

Configuring SNAT with HSRP
!
ip nat Stateful id 1
redundancy SNATHSRP
mapping-id 10
ip nat pool SNATPOOL1 11.1.1.1 11.1.1.9 prefix-length 24
ip nat inside source route-map rm-101 pool SNATPOOL1 mapping-id 10 overload
ip classless
ip route 11.1.1.0 255.255.255.0 Null0
no ip http server
ip pim bidir-enable

Configuring SNAT Primary/Backup
!
ip nat Stateful id 1
primary 10.88.194.17
peer 10.88.194.18
mapping-id 10
!
ip nat Stateful id 2
backup 10.88.194.17
peer 10.88.194.17
mapping-id 10

thank you - Arif
