RIPng (RIP next generation) is an extension of RIPv2 for support of IPv6, the next generation Internet Protocol. [12] The main differences between RIPv2 and RIPng are: Support of IPv6 networking. While RIPv2 supports RIPv1 updates authentication, RIPng does not. IPv6 routers were, at the time, supposed to use IPsec for authentication. [citation ...
Interior gateway protocols type 2, distance-vector routing protocols, such as Routing Information Protocol, RIPv2, IGRP. Exterior gateway protocols are routing protocols used on the Internet for exchanging routing information between Autonomous Systems, such as Border Gateway Protocol (BGP), a path-vector routing protocol.
The oldest routing protocol, and the oldest distance-vector protocol, is version 1 of the Routing Information Protocol (RIPv1). RIPv1 was formally standardised in 1988. [2] It establishes the shortest path across a network purely on the basis of the hops, that is numbers of routers that need to be passed to reach the destination network.
Route poisoning is a method to prevent a router from sending packets through a route that has become invalid within computer networks. Distance-vector routing protocols in computer networks use route poisoning to indicate to other routers that a route is no longer reachable and should not be considered from their routing tables.
This contrasts with distance-vector routing protocols, which work by having each node share its routing table with its neighbors, in a link-state protocol, the only information passed between nodes is connectivity related. [7] Link-state algorithms are sometimes characterized informally as each router "telling the world about its neighbors." [8]
An interior gateway protocol (IGP) or interior routing protocol is a type of routing protocol used for exchanging routing table information between gateways (commonly routers) within an autonomous system (for example, a system of corporate local area networks). [1] This routing information can then be used to route network-layer protocols like IP.
Stating that RIP uses a hop count of 15 in the summary, while correct for RIPv1, it is not correct for today's use. The majority of RIP users will be using the latest version in the devices they purchase.

Administrative distance (AD) or route preference [1] is a number of arbitrary unit assigned to dynamic routes, static routes and directly-connected routes. The value is used in routers to rank routes from most preferred (low AD value) to least preferred (high AD value).
