Configuring a router for a basic policy-based routing (PBR) topology
While deploying your Exinda Appliance in a basic PBR topology, you must specify how the router should handle traffic coming from the out-of-path Exinda Appliance, the WANWide Area Network, and the LANLocal area network.
CAUTION
Configure your router using IPInternet protocol addresses that correspond to your network. The IP addresses and netmasks used in this guide are for demonstration purposes only.
- Launch the router command line interface.
- To enter privileged EXEC (enable) mode, at the prompt run the command:
hostname > enable - To enter configuration (config) mode, at the prompt run the commands:
hostname # configure terminal - Configure the interface parameters for the Exinda Appliance installed out-of-path (Gig0/0).
The hostname # prompt appears.
The hostname (config)# prompt appears.
- 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 GigabitEthernet0/0 - 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
