Lab name: Cisco routing dynamic PNAT configuration

Lab Topology:

Lab environment: 1 or 3 routers

2. One switch

Router 0 Border Router (intranet and extranet)

Router 1 Border Router (intranet and extranet of public network)

Pouter 2 intranet router (the internal network of the public network)

3. Two PC

Pc2 pc3

Experimental idea: first configure the addresses of the three routers

Router0 g0ap0 port is the intranet gateway 192.168.1.254Universe 24.

Router0 g0ax 1 is the public network address 100.1.1.1Accord24

Router1 g0swap 0 is the public network address 100.1.1.2, the public network address 24 Router1 g0, the public network gateway 200.1.1.1, the public network gateway, 24 Router2 g0, the public network address, 200.1.1.2, the public network address, 200.1.1.2.

The steps of the experiment:

1. Configure PC address:

Pc2:

IP: 192.168.10.1/24

Gateway: 192.168.10.254

Pc3

IP: 192.168.10.2/24

Gateway: 192.168.10.254

2. Configure Router 0

Continue with configuration dialog? [yes/no]: no

Press RETURN to get started!

Router > enable

Router#

Router#configure

Configuring from terminal, memory, or network [terminal]?

Enter configuration commands, one per line. End with CNTL/Z.
