Section: part 4
Explanation Explanation/Reference: When a packet is received at the interface where Unicast RPF and ACLs have been configured, the following actions occur: Step 1: Input ACLs configured on the inbound interface are checked. Step 2: Unicast RPF checks to see if the packet has arrived on the best return path to the source, which it does by doing a reverse lookup in the FIB table
