Waas Setup Clarification

[Simon Young]

I am new to Waas and I would like some clarification on my setup

I have 3 * 574 devices and a CM (see diagram)

One device is remote and inline- Site 3

I have a Management device and an application accelerator at site 1

I have a an application accelerator at site 2

The devices at Site 1 and 2 are all on the same Mgmt LAN using their Gig 1/0 interfaces (10.10.10.1,2 and 3).

Sites 1 and 2 are separate sites but the core switches are linked over a wan

The two Cisco 3925 routers are conencted to two different  MPLS circuits

Site 1 & 2 Cisco 3925 routers are using a tertiary interface to connect to the 574 on a private LAN

I tried going live at the weekend with this set up using GRE tunnels and experienced loss of connectivity to devices behind the router

I shutdown the gig 0/1 interface and everything was restored to normal

The 3925 router configurations are as follows (same at both sites)

!

configure terminal

ip wccp 61

ip wccp 62

!

interface GigabitEthernet0/0

!   Updates the LAN interface

ip wccp 61 redirect in

!

interface GigabitEthernet0/2

!   Updates the WAN interface

ip wccp 62 redirect in

!

default interface gigabitEthernet 0/1

interface gig 0/1

ip address 172.30.10.1 255.255.255.252

description P2P WAAS

ip wccp redirect exclude in

no shut

exit

I have router lists configured to point at the 3925 for both WAAS devices.

When I look at the default gateway for the 172.30 interfaces it is pointing at the other LAN (the management) 10.10.10.x. Will this matter if I have a router list configured?

Should I be using WCCP Layer 2 as my router/WAE are directly connected. Can 3925 routers handle this?

Also I have just realized that the primary interface is set to gig 1/0, would it need to be set to gig 2/0 on the devcies connected to the routers

Any help much appreciated

[gaursin2]

can u share the config of your WAE site-1 also. From router config everything is good except "ip wccp redirect exclude in" on gi0/1. this command is not required in your setup.

Your setup is correct, but network outage is because of redirection loop, probably because of wrong route in wae or something. will discuss once get a config...

[Simon Young]

Thanks for responding to my questions.

I have edited out the domain name and NTP information. The configuration is the one from the weekend. I have not updated the primary interface or changed the method for redirection  i.e. to WCCP Layer 2

The 172.30.1.x subnet is not being routed

Thanks for your help in advance

see as per my understanding of the issue i will try to explain what might actually happened during outage.

See there are tow possibility of how WAE return the traffic (optimized or non optimized) back to network, its called egress method. first one which is default is IP forwarding where in WAE forward the traffic to its default gateway. Which in our case is 10.10.10.10. Now you have not mentioned what is this device but i beleive its some SVI on switch. So all the redirected traffic from router gig0/1 interface, reach WAE. But wae when transmit back to network it transmit it to 10.10.10.10. Now WAAS do not modify the packet headers (IP addresses). So 10.10.10.10 will treat this as normal IP packet with original clinet source and original server destination and will transmit the packet back to WAN router. Wan router seeing this packet coming back from LAN interface will redirect back to WAE. This caused a loop.

the second forwarding method is GRE (egress-method negotiated-return intercept-metod wccp), where WAE will encapsulate the return packet in GRE tunnel and send to WCCP redirecting router. So with this there will be no loop and router will get this packet via tunnel interface rather LAN interface.

Hope u got my point above and possible reason what went wrong that day.

This all happen because of a switch configured as default gateway in WAE. so either you change the forwarding method or chaging the default gateway in WAE will resolve the same.

[Simon Young]

Yes, I understand your description, its alot clearer than some of the documentation I have been reading.

Just to clarify, I do have a SVI on a switch. That is the gateway for the vlan where all of my WAAS management interfaces are connected to (gig 0/1).

I noticed the default gateway issue. I did change this, so that the gateway was 172.30.10.1. The problem is that this will then stop my access to the management IP address via Telnet. So the Gig 1/0 interface 10.10.10.1 uses the gateway of 172.30.10.1? I can still make changes from the CM to this end device, so I am assuming that they are still talking to each other. So I guess it doesn't matter???

So my options are either - change the gateway

Or I should use these settings under wccp

Should I also

set my primary interface to gig 2/0

As another option

Could I set the Redirect/Return method to WCCP L2 with Egress of IP forwarding and the 172.30.10.1 gateway? As my devices are directly connected. To avoid the extra lookups of GRE?

[gaursin2 · Accepted solution]

Hi,

primary interface is the interface which it uses to communicate to CM. i don't understand why there is break in communication between CM and WAE when you change the gateway on WAE, i saw you said their IP address are 10.10.10.0/24 segment, so they are L2 neighbor.

regarding your second option, that is good option of changing redircet method to L2 and default IP forwarding, with gateway directly to redirecting router. A simple and widely deployed WAAS setup.

[Simon Young]

Thanks for your assistance with this, it is very much appreciated.

Your description of the fault as correct - I used find match “Routing Loop” syslog.txt. I could see routing loop errors for the entire time period where I had the intterface up

I will be using option two

Finally, I lost connectivity to the devices from a remote location (I didn't mention this). This was obviously due to the routing loop.
