Talk:Interior gateway protocol
Maybe mention that link state protocols can use an algorithm such as Dijkstra to calculate shortest paths? Cheesy
The second line of the summary states: "In contrast an exterior gateway protocol is for determining network reachability between autonomous systems (AS) and makes use of IGPs to resolve route within an AS." However, the first line does not define the use of IGP. If "the use of IGPs is to resolve routes within an autonomous system" then the article should say so explicitly in the first line or paragraph fo the summary.
== Wrong link == The link near the beginning to exterior gateway protocol is not really correct as in the text it's a reference to the general class of exterior gateway protocols and there is no such page yet. Instead it points to the page for the specific protocol Exterior Gateway Protocol. Unfortunately the class of protocols and the specific protocol have the same name. -- Dougher (talk) 22:08, 17 January 2013 (UTC) exterior gateway protocol has been split into two pages which does help clarify things here.
The article does not explain the name. I remember when having my first contact with IGPs, I always wondered, why they are called "gateway" protocols and not routing protocols. Then I realized that their purpose is finding the most suitable gateway router that can deliver the packet to its destination. — Preceding unsigned comment added by 2003:C2:43F6:D400:4938:BCD9:113E:29D2 (talk) 19:19, 18 February 2017 (UTC)
