Using the network below, show the complete routing tables for:a) R1b) R3You must include the following 4 fields in each of your routing tables: Mask, Destination, NextHop and Interface. Entries in your routing table should be sorted in the following order {Direct,Host-Specific, Network-Specific, Default).InternetaoOR1130.60.0.0a1 74.100.11.1c1co130.60.95.674.0.0.074.102.94.33R3bo74.101.9.3130.60.210.19 130.60.210.14R2b1 221.53.49.39b2221.53.49.0221.53.49.128Site: 221.53.49.0

Let's look at that terminology: Next-hop: This is the next router or network to which you have to forward the packet as well. Mask: The subnet masks will be predefined as a class-based classification. the GUI is nothing more than the exit lines through the router, which you may think of as paths. Let's look at the routers now, one by one. R1 ROUTER: You can see that the router only has 2 interfaces,a1, a0 Now just imagine, if you are at R1, then if packets want to go to the INTERNET, what their next hop will be, it should be a0 interface, since INTERNET is huge, where the packets will go is not specified here. Similarly, we can also think of others. Just think that you're at R1, then think about all possible destinations and roads, MASK DESTINATION NEXT HOP INTERFACE 74.255.0.0 INTERNET a0 a0 221.255.255.0 221.53.49.128 R2 (74.101.9.3) a1 221.255.255.0 221.53.29.0 R2 (74.101.9.3) a1 255.255.255.255 Default value a0 a0Likewise, we can see it for ROUTER R3 Look at the diagram now, R3 has connections to all networks, R1 has but also 1 additional network, so its table would be R1's extension.
