طب انا اعرف ان بروتوكول ال RIP و IGRP من ال Distance Vector Routing Protocols
بس مكتوب فى ال Material بتاع Cisco Academy
ان ال RIP بيعتمد على ال hob count زى ما انت بتقول
... لكن ال IGRP بيعتمد على ال bandwidth , delay , load ,
طب ازاي وهو distance vector ؟
ودي نسخة من الكلام اللى قريته
Routing Information Protocol (RIP) was originally specified in RFC 1058. It has the following key characteristics:
Hop count is used as the metric for path selection.
If the hop count for a network is greater than 15, RIP cannot supply a route to that network.
Routing updates are broadcast or multicast every 30 seconds, by default.
Interior Gateway Routing Protocol (IGRP) is a proprietary protocol developed by Cisco. IGRP has the following key design characteristics:
Bandwidth, delay, load and reliability are used to create a composite metric.
Routing updates are broadcast every 90 seconds, by default.
IGRP is the predecessor of EIGRP and is now obsolete.
