What Is the Difference Between Routing Table and Forwarding Table?
Answer: The forwarding table is the structure for the optimization of the process that looks at the address during the package transfer, and contains the MAC address information. The routing table’s main purpose is to calculate the modification in the topology and the routing table has the IP address of the next hope.
Routing table:
A set of the rules that is present in the form of the table define the data packets’ movement such as their direction in an internet protocol. the device with the IP address must use the routing table such as the switches, router, etc.
The routing table contains the data which is required to move the packets to the best possible path for the destinated address. The packet has the data related to the source and destination. The devices get the instruction for packets forwarding to the next hop in a network through the routing table. The routing table entry contains the following entries:
Forwarding Table:
The forwarding table determines the process by the packets forwarded of the switch or router in a network they are also referred to as the flow tables. The forwarding tables are processed by matching the header field like the IP address of the destination and then forwarding the packet to the specific port. The open flow 1.0 contains the 12 headers filed of the packets which are useful in the table matching.it includes the MAC address of the source and destination, ether type, source and destination IP address, IP protocol, TCP source, and destination port. the open flow controller work by moving the match IP field in the table with the use of API open flow.
