Routing Question - CEF

[js358]

Hello All:

Have 3 T1's that we planned using cef per packet but it kills our application.

Disabled it and now configured for per destination. I am a little confused about something.

I have 10.0.3.1 as the gateway for my clients. This interface - ip nat inside.

Have all clients statically mapped out

I have several questions. IP CEF per destination should make these T1's behave a seperate T1's correct. What I mean is....in order to get traffic to route out ANY of the 3 serial interfaces I have the follwoing in my config....is this correct? If not can someone point out the mistake....thanks

ip route 0.0.0.0 0.0.0.0 ser0/0

ip route 0.0.0.0 0.0.0.0 ser0/1

ip route 0.0.0.0 0.0.0.0 ser0/2

FA0/0 - 10.0.3.1 ip nat inside

ser0/0 - ip nat outside

ser0/1 - ip nat outside

ser0/2 - ip nat outside

By doing this, traffic can route out any T1 correct?

Thanks

This configuration looks correct indeed. Configuring per-destination loadsharing will cause the egress interface to be selected based on hashing the source and destination IP address. If you want to determine what interface will be used for a particular source, destination pair, use the "sh ip cef exact-route .

Hope this helps
