Route Map Difference

Is there any difference in how Route Map processes the packets when applied in PBR and route redistribution?

Thanks in advance...

Re: Route Map Difference

Hi Arun,

Route maps are to check some conditions based to classified traffic in ACLs and then take decision based on that condition is matched or not. So they can be used in NAT, QOS, Redistribution, PBR etc.

Their sole purpose is to check if condition matches or not if yes then it will take some actions. Thos actions can be different for PBR, route redistrobution or NAT or QOS etc.

Re: Route Map Difference

To add to what ankur mentioned, PBR is source based routing as against normal destination based routing. Next hop of the pkts is decided based on src ip address.

I do not clearly understand your question. When a route map is used for PBR and when a route map is used to control redistribution clearly the way that it inspects will be different (PBR can look at source address and source port, or protocol type, etc while redistribution will simply examine the prefix) and the action taken is clearly different (PBR will set a different next-hop, or different output interface, or different default route while for redistribution the route map only permits or denys and does not set anything).

But I am not sure that this is what you meant when you ask about:

how Route Map processes the packets

perhaps you can clarify?
