waas setup part 2 out of 3

waasp2

This is part 2 of the waas setup.  In part one we looked over a simple infrastructure with WAAS technology.  Here I will guide everyone through the remote site.  What is nice about the newer ISR(inegrated service routers) from cisco is the WAAS option.  A waas module listed below

WAAS Module

WAAS Module

Can simply fit into most ISR 29xx,28xx,39xx etc.  All the device is is a module which one can simply session into or connect into via the managment IP on the module.  For example here is the configuration on the router for the module.

interface SM1/0
ip address 10.0.0.1 255.255.255.0  This is the IP address to get to the router
service-module ip address 10.0.0.2 255.255.255.0  Management to get into the Module from the outside world. 
!Application: Restarted at Thu Nov  8 16:23:02 2012
service-module ip default-gateway 10.0.0.1 Default gateway for the WAAS to get to the rest of the network.  
no keepalive
end

We Can session in the WAAS by running the following command. service-module SM 1/0 session

Once you session in there are a few commands you will want to run.

interface GigabitEthernet 1/0
ip address 10.0.0.2 255.255.255.0 Creates the Interface handing off to the router
exit
ip default-gateway 10.0.0.1  Sets the SM1/0 interface as the default gateway
ip name-server x.x.x.x Sets the DNS server
ntp server x.x.x.x Sets the NTP server
wccp router-list 8 x.x.x.x Sets the router that is able to redirect into the waas make sure the ISR’s Loopback IP is here otherwise it will not work.
wccp tcp-promiscuous router-list-num 8 Sets ACL router list 8 as routers allowed to do redirection.
wccp version 2 Uses Version 2 of WCCP
central-manager address x.x.x.x This is the address of the WAAS Central manager back in the Data center this module communicates to this is needed.

Now On the Router.

ip cef
ip wccp 61 Creates WCCP 61
ip wccp 62 Creates WCCP 62
ip wccp 61 redirect-list WAAS  Creates WCCP redirect list with The WAAS ACL
ip wccp 62 redirect-list WAAS
ip access-lists extended WAAS
permit tcp any any eq 80

wccp version 2

interface Se0/0
description to ISP1
ip wccp 62 redirect in

intSe0/1
description to ISP2
ip wccp 62 redirect in

interface Fa0/1
description LAN interface
ip wccp 61 redirect in

There are three general ways of redirection into a WAAS unit.  We are covering the most common method of redirection WCCP.

1.)WCCP
2.)PBR
3.)Inline mode

The most important part of the configuration is getting the correct interfaces for redirection.  Also getting the ACL in for redirection otherwise it will redirect all TCP traffic into the WAAS without the WAAS ACL.  Now on the router if I issue the sh ip wccp I should see traffic redirecting into my WAAS SM.
