Overview

To use the Virtual Router Redundancy Protocol (VRRP) with PBR (Policy-Based Routing), you should specify the behavior of the router interfaces that connect to the LAN, WAN, and the out-of-path Exinda appliances.

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

Process

1. Launch the router's CLI.
   • To enter the privileged EXEC (enable) mode, run the following command at the prompt:
     
     

     hostname > enable

   • The hostname # prompt appears.
   •  To enter the configuration (config) mode, run the following command at the prompt:
     
     

     hostname # configure terminal

   • The hostname (config) prompt appears.
2. Configure the interface parameters for the switch installed between the router and the out-of-path Exinda Appliances (Gig0/0).
   1. Specify the interface to configure:
      
      

      hostname (config)# interface GigabitEthernet0/0

   2. Set the IP address of the out-of-path Exinda Appliance:
      
      

      hostname (config-if)# ip address 10.10.10.1 255.0.0.0

   3. Set the duplex and speed parameters for the interface:
      
      

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

3. Configure the parameters for the WAN interface (Gig0/1).
   1. Specify the interface to configure:
      
      

      hostname (config)# interface GigabitEthernet0/1

   2. Set the IP address and netmask of the WAN interface:
      
      

      hostname (config-if)# ip address 64.65.66.1 255.255.255.0

   3. Set the route map for policy routing to asymmetrical:
      
      

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

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

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

4. Configure the parameters for the LAN interface (Fa0/1).
   1. Specify the interface to configure:
      
      

      hostname (config)# interface FastEthernet0/1

   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 the route map for policy routing with the name Asym:
      
      

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

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

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

5. Create an access list named 120 that allows the 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

6. Configure the route map to enable 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 10.10.10.100
