Question

Dears,

I need unique and type answer (not hand written and no image) for this question:

Let's consider below given network of MPLS/IP routers with Tunnel. Draw routing table for Router R1 Address A1 R3 nterface 11 R2 R4 R1 R5 nterface 12 R7 Address A2 R8 Answer Destination Output Interface Next Hop Metric 2.2.2.2 3.3.3.3 4.4.4.4 5.5.5.5 6.6.6.6

Answer 1

• Routing Table:-​
  • It is also known as Routing Information Base.(RIB)
  • It is a data table stored in a router which lists the routes to particular network destinations and also the metrics associated with those routes.
  • It consists of the following information:-
    • Destination - IP Address of the packet's final destination.
    • Output Interface - The network Interface the device should use while forwarding the packet to the next hop or the final destination.
    • Next Hop - For which the packet is forwarded.
    • Metric - Cost assigned to each available route so that the most cost effective path can be chosen.

Destination	Output Interface	Next Hop	Metric
2.2.2.2	Interface I1	R2/A1	1
3.3.3.3	Interface I3	R2/A1	2
4.4.4.4	Interface I1	R2/A1	3
5.5.5.5	Interface I1	R2/A1	4
6.6.6.6	Interface I2	R6/A2	1
7.7.7.7	Interface I2	R6/A2	2
8.8.8.8	Interface I1	R1/A2	3

Metric cost is calculated based on the shortest path to the destination because no weights were given. Next hop is also determined based on the shortest path
