I have a pair of 4500x in VSS mode and i have 100-150x SVIs and i have PBR under those SVIs and i am changing their next-hop, i want to know PBR and changing next-hop happens in TCAM, hardware or it is changing the next-hop by CPU? Thank you.

  • Can you rephrase your question? It’s difficult to know what exactly you’re asking.

If there's no tunneling like GRE and CEF is enabled the PBR is handled by CEF.

If you want to fast switch the PBR you can use ip route-cache policy under the interface.
