Switching methods that routers use, define the way how pkts are handled by router. There are 3 methods:
Process Switching: legacy switching type. Each & evry pkt does a routing lookup to find reachability to destination, next-hop, & the interface from where next-hop is available.
Fast Switching: 1st pkt is process switched. Stores the info in a cache, thus reduce the router lookup time for following pkt to same destination. The cache info is timed out at regular intervals.
CEF: no process switching for 1st pkt. Router builds 2 tables, cef table that defines reachability of network, & adjacenccy table to define the next-hop & interface via which nxt-hop is reachable. Cache is not aged out.

Introduction The purpose of this document is to demonstrate the Open
Shortest Path First (OSPF) behavior when the V-bit (Virtual-link bit) is
present in a non-backbone area. The V-bit is signaled in Type-1 LSA only
if the router is the endpoint of one or ...
