thanks for your explanation it is really fantastic.
One more point I would like to stress here is that the EIGRP protocol itself
is well equiped handling the situations like preventing routing loops. In
what way?
EIGRP allot 2 different AD values, one to internal(90) and another external
routes (170). The routing loops are managed this way.
In the case of RIP, IGRP, OSPF the story is slightly diferent as they each
have got a single AD value to both internal as well as external routes.
Probably Cisco might have plans to comeout with an Enhanced-OSPF in future
like their EIGRP. They might prefer O,IA,E1 and E2 are assigned different AD
values. Currently Cisco follows an RFC way of implementing the OSPF.
thanks
