Hello. I have a question regarding the use of policy based routing. I've always thought of it as a way to selectively change routing in exceptional circumstances.
I've come across an implementation where it is being used to explicitly set a next-hop ip for 99% of all traffic headed from an application behind a pair of of stacked 3750s. The default route on these layer 3 switches is set to a 192.168.x.x IP which is part of a management network. The PBR is in place to send the outbound application traffic towards a firewall and out to the internet. Part of the reasoning for doing this was because the application will require only a few separate class C's and the management network has many more routes. A route-map matching an access-list or prefix-list for the basis of PBR on the outbound application traffic would contain fewer lines of configuration and thus it was deemed more elegant to set up PBR for the application traffic rather than the management traffic. I'm having a tough time finding best-practices information on the use of PBR and was wondering what cisco-nsp thought of this setup. _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
