The forwarding paths used in a network depend on the forwarding tables installed in the network nodes. Consider the network shown below with the forwarding tables.

The forwarding paths used in a network depend on the forwarding tables installed in the network nodes. Sometimes, these forwarding tables must be configured manually.

In this network, which of the forwarding tables below ensures that both :

• A and B can exchange packets in both directions
• the path from A to B is the reverse of the path from B to A

The forwarding paths used in a network depend on the forwarding tables installed in the network nodes. Sometimes, these forwarding tables are configured manually and an incorrect configuration may cause some paths to be impossible.

In this network, A can send packets to B, but when B sends a packet to A, this packet never reaches its destination. Among the following forwarding tables, which is the one that ensures that A can exchange packets with B ?
