An auditor asks how filter-based forwarding relates to VRF-based tenant isolation in the municipal fabric. Which statement best describes their complementary roles?
Select an answer to reveal the explanation.
Short Explanation
VRFs are the separate filing cabinets; FBF is the clerk who pulls one folder and walks it to the inspection room. Isolation and selective steering work together—they are not an either-or switch.
Full Explanation
Routing instances (VRFs) provide table separation for tenant isolation. FBF uses packet filters to redirect selected flows into alternate forwarding contexts without requiring every policy outcome to be a full VRF redesign. The mechanisms complement each other: isolation defines the tables, and FBF selectively moves matching traffic between or into those contexts. They are not mutually exclusive, and FBF does not by itself replace multitenant routing-instance design.
