A museums department must force permit-office laptop traffic through a DPI path while leaving servers on normal destination-based routing. Which feature applies that exception?
Select an answer to reveal the explanation.
Short Explanation
Normal routing is “follow the destination street signs.” PBR is the special detour sign for permit-office laptops only—send them past DPI while servers keep using the ordinary map. Match the right traffic, set the next hop, leave everyone else’s RIB alone.
Full Explanation
Policy-based routing overrides destination-based forwarding for matched traffic by setting next hop, interface, or other actions. That lets laptop flows visit a DPI path without changing how servers reach destinations via the RIB. Changing OSPF AD globally, stretching VLANs with VTP, or enabling UDLD does not surgically redirect one user class. Implement PBR carefully with CEF and match ACLs, and verify fail-open or fail-closed behavior for the intended class only.
