Hello friends,

I will say that its depend on your topology, because network
administrator configure routing protocol on the based of his
topology.

Say if you have back to back connection then STATIC is
best,due to less of AD value. It has 1/0 of AD value

But when we will talk about middle organization then we can
say that RIPV1/V2 is best because it has features to work on
different subnet mask, and Trigger update where in static if
any change occur than it will be tough to configure in each
and every router. RIP is based on only for 15 maximum host.
It has 120 of AD value

okay now EIGRP is the best if you are using many routers of
same vendors because it work on DUAL method, means it never
count hop it work on Bandwidth, metric, etc. which has 90 of
Ad value

and OSFF is best when you are using different vendor router
because EIGRP work only on cisco router. so that time OSPF
would be best. which has 110 of AD value.

Someone will says that less AD value protocol is best, but
I'll say that its only to put priority to
different-different routing protocol.
