Overview

To use the Virtual Router Redundancy Protocol (VRRP) with Policy-Based Routing (PBR) and IP Service Level Agreement (SLA) tracking, you should 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 the VRRP with PBR and IP SLA tracking.

Process

1. Launch the router's 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.
2. Configure the interface parameters for the Exinda appliance installed out-of-path (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 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 verify-availability 10.10.10.100 1 track 1

7. Configure the IP address of the VRRP group and the schedule of the IP SLA operation.
   
   

   hostname (config)# ip sla 5
   hostname (config-ip-sla)#icmp-echo 10.10.10.100
   hostname (config)#ip sla schedule 5 life forever
   start-time now

8. Set the tracking of the availability of the IP SLA operation.
   
   

   track 1 ip sla 5
   delay down 2 up 2
