what is distance vector protocol link state protocol and
what is the diffrence between them

Answer Posted / umamaheswararao ch

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.
