Q3:Explain link state routing vs distance vector routing.

A:

See Fig. 1-1 below. If all routers were running a Distance Vector protocol, the path or 'route' - See more at: http://www.inetdaemon.com/tutorials/internet/ip/routing/dv_vs_ls.shtml#sthash.pMwGkpMj.dpuf

See Fig. 1-1 below. If all routers were running a Distance Vector protocol, the path or 'route' chosen would be from A  B directly over the ISDN serial link, even though that link is about 10 times slower than the indirect route from A  C  D  B.
A Link State protocol would choose the A  C  D  B path because it's using a faster medium (100 Mb ethernet). In this example, it would be better to run a Link State routing protocol, but if all the links in the network are the same speed, then a Distance Vector protocol is better.
