IS path vector routing algorithm closer to the distance vec

: IS path vector routing algorithm closer to the distance vector routing algorithm or to the link state routing algorithm? Explain.

Solution

The path-vector routing algorithm is truly distance-vector routing using the finest path instead of the direct distance as the metric. Each node first create a forwarding table. Assuming it can only arrive at instant neighbors . The forwarding table is slowly better as path vectors turn up from the instant neighbors.
