PBR route vs connected route

Jump to solution

Hi guys,

 

I know PBR takes precedence over the IP routing table. But does a PBR route have precedence over a connected route or only over static and routing protocols learned routes? Is this CP behaviour or standard behaviour?

Like any other route with a higher preference, it will take over when there is a smaller subnetmask. So when your interface has a /27 mask and you add 1 or 2 PBR routes with a /28 that overlaps the interface route it take the PBR.

Hi Maarten

 

But what happens when the connected route has /27 mask and the PBR route has /27 mask as well?

Then the interface route will take preference, it always has the highest priority.

Ok, last doubt, in this two cases:

1 - Static route with /27 mask and PBR route with /27 mask? Which will take precedence?

2 - Static route with /28 mask and PBR route with /27 mask? Which will take precedence?

1 - to my knowledge the PRB will take preference.

2 - easy the /28 will take preference over a /27 irrelevant here is the type of route. Smaller mask will always take preference over larger mask.
