Configure private address pools for NAT users.
NOTE
Configure two private NAT address pools that correspond to the master and backup public NAT
address pools respectively.
# On Router A, create a NAT user group named g1, set the master address pool name to
nat-1, and configure the gateway address 173.16.129.1/16 and an address range from
173.16.129.2 to 173.16.129.254 for the master address pool; set the backup address pool
name to nat-2bak, and configure the gateway address 173.17.129.1/16 and an address range
from 173.17.129.2 to 173.17.129.254 for the backup address pool.
[RouterA] user-group g1
[RouterA] ip pool nat-1 bas local
[RouterA-ip-pool-nat-1] gateway 173.16.129.1 16

[RouterA-ip-pool-nat-2bak] quit
# On Router B, create a NAT user group named g2, set the master address pool name to
nat-2, and configure the gateway address 173.17.129.1/16 and an address range from
173.17.129.2 to 173.17.129.254 for the master address pool; set the backup address pool
name to nat-1bak, and configure the gateway address 173.16.129.1/16 and an address range
from 173.16.129.2 to 173.16.129.254 for the backup address pool.

Configure access domains for NAT users.
# On Router A, create a domain named nat1, bind address pool nat-1 to this domain, and
bind user group g1 and NAT instance nat1.
[RouterA] aaa
[RouterA-aaa] domain nat1
[RouterA-aaa-domain-nat1] ip-pool nat-1
[RouterA-aaa-domain-nat1] user-group g1 bind nat instance nat1
