Configure the Router for PBR with Two Subnets

Specify the behaviour of the router interfaces connecting to the the LAN, the WAN, and the out-of-path Exinda appliances.

1. Launch the router command line interface.

• To enter privileged EXEC (enable) mode, at the prompt type the following command:

  hostname > enable

  The hostname # prompt is displayed.

• To enter configuration (config) mode, at the prompt type the following commands:

  hostname # configure terminal

  The hostname (config)# prompt is displayed.

2. Configure the parameters for the LAN interface (Fa0/1/1).

   1. Specify the interface to configure.

      hostname (config)# interface GigabitEthernet0/0

   2. Set the IP address and netmask of the LAN interface.

      hostname (config-if)# ip address 172.16.12.1 255.255.0.0

   3. Set a description for what the router interface is connecting to.

      hostname (config-if)# description Connected to EX-IN

   4. Set the route map for policy routing with the name DivtEx1theEx2.

      hostname (config-if)# ip policy route-map DivtEx1theEx2

   5. Set the duplex and speed parameters for the interface.

      hostname (config-if)# duplex auto

      hostname (config-if)# speed auto

3. Configure the interface parameters for the out-of-path Exinda appliance #1 (Gig0/0/0).

   1. Specify the interface to configure.

      hostname (config)# interface GigabitEthernet0/0/0

   2. Set a description for what the router interface is connecting to.

      hostname (config-if)# description Connected to EX-OOP-1

   3. Set the IP address of the out-of-path Exinda appliance.

      hostname (config-if)# ip address 10.10.10.1 255.255.255.0

   4. Set the duplex and speed parameters for the interface.

      hostname (config-if)# duplex auto

      hostname (config-if)# speed auto

4. Configure the interface parameters for the out-of-path Exinda appliance #2 (Gig0/0/1).

   1. Specify the interface to configure.

      hostname (config)# interface GigabitEthernet0/0/1

   2. Set a description for what the router interface is connecting to.

      hostname (config-if)# description Connected to EX-OOP-2

   3. Set the IP address of the out-of-path Exinda appliance.

      hostname (config-if)# ip address 10.10.20.1 255.255.255.0

   4. Set the duplex and speed parameters for the interface.

      hostname (config-if)# duplex auto

      hostname (config-if)# speed auto

5. Configure the parameters for the WAN interface (Gig0/1).

   1. Specify the interface to configure.

      hostname (config)# interface GigabitEthernet0/1

   2. Set a description for what the router interface is connecting to.

      hostname (config-if)# description Connected to WAN

   3. Set the IP address and netmask of the WAN interface

      hostname (config-if)# ip address 64.65.66.1 255.255.255.0

   4. Set the route map for policy routing to asymmetrical.

      hostname (config-if)# ip policy route-map DivtEXOOP1thenEXOOP2

   5. Set the duplex and speed parameters for the interface.

      hostname (config-if)# duplex auto

      hostname (config-if)# speed auto

6. Create an access list named 120 that allows devices in the specified IP address range to access the network.

   hostname (config)# access-list 120 permit ip 172.16.0.0 0.0.0.255 64.65.66.0 0.255.255.255

   hostname (config)# access-list 120 permit ip 64.65.66.0 0.255.255.255 172.16.0.0 0.0.255.255

7. Configure the route map to allow access to the routes specified in the access list (140), and route the traffic to the router.

   route-map DivtEXOOP1thenEXOOP2 permit 10

   match ip address 140

   set ip next-hop 10.10.10.2 10.10.20.2
