Overview

While deploying your Exinda Appliance in a basic PBR topology, you must specify how the router should handle the traffic coming from the out-of-path Exinda Appliance, the WAN, and the LAN.

This article provides step-by-step instructions on how to configure a router for a basic PBR topology.

CAUTION!

Configure your router using the IP addresses that correspond to your network. The IP addresses and netmasks used in this article are for demonstration purposes only.

Process

Launch the router's Command-Line Interface (CLI).

To enter the privileged EXEC (enable) mode, run the following command:
```
hostname > enable
```

The hostname # prompt appears.

To enter the configuration (config) mode, run the following command:
```
hostname # configure terminal
```

The hostname (config)# prompt appears.

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

Specify the interface to configure:

hostname (config)# interface GigabitEthernet0/0

Set the IP address of the out-of-path Exinda Appliance:
```
hostname (config-if)# ip address 10.10.10.1 255.0.0.0
```

Set the duplex and speed parameters for the interface:

hostname (config-if)# duplex auto
hostname (config-if)# speed auto

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

Specify the interface to configure:

hostname (config)# interface GigabitEthernet0/1

Set the IP address and netmask of the WAN interface:

hostname (config-if)# ip address 64.65.66.1 255.255.255.0

Set the route map for policy routing to asymmetrical:
```
hostname (config-if)# ip policy route-map Asym
```

Set the duplex and speed parameters for the interface:

hostname (config-if)# duplex auto
hostname (config-if)# speed auto

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

Specify the interface to configure:

hostname (config)# interface FastEthernet0/1/1

Set the IP address and netmask of the LAN interface:

hostname (config-if)# ip address 172.16.12.1 255.255.0.0

Set the route map for policy routing with the name Asym:
```
hostname (config-if)# ip policy route-map Asym
```

Set the duplex and speed parameters for the interface:

hostname (config-if)# duplex auto
hostname (config-if)# speed auto

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 0.0.255.255 64.65.66.0 0.0.0.255

hostname (config)# access-list 120 permit ip
64.65.66.0 0.0.0.255 172.16.0.0 0.0.255.255

Configure the route map to allow access to the routes specified in the access list (120), and route the traffic to the router.

route-map Asym permit 10

match ip address 120

set ip next-hop 10.10.10.2
