Based on the image, the network consists of five nodes (A, B, C, D, and E) connected by links with associated link costs. To implement distance vector routing for this network and find the routing table and least cost distance vectors for various nodes, the following steps can be taken:
Step 1: Initializatio
At the beginning, each node sets its distance vector to all other nodes in the network to infinity, except for its own distance vector, which is set to 0. Each node also broadcasts its distance vector to all of its neighbors.
Step 2: Update
Each node updates its distance vector based on the distance vectors received
After step 2, the distance vectors of each node are updated based on the distance vectors received from its neighbors. The update process involves computing the minimum cost path to each node based on the distance vectors received from its neighbors and updating its own distance vector accordingly. This process is repeated until no further updates are required.
Step 3: Routing Table Each node uses its final distance vector to construct its routing table, which lists the next hop and associated cost for each destination node. The routing table is used by the node to forward data packets to their intended destination.
After step 3, we have constructed the routing tables for each node in the network. These routing tables will be used to forward data packets from one node to another.
The routing table for Node A is:
This routing table indicates that for Node A to send a packet to Node B, it should forward the packet directly to Node B with a cost of 4. Similarly, to send a packet to Node C or Node E, it should forward the packet directly to Node C with a cost of 5. To send a packet to Node D, it should forward the packet to Node B with a cost of 8.
We can repeat this process for all nodes in the network to obtain their respective routing tables.
he final answer includes the routing tables for each node. Here are the routing tables for all nodes in the network:
