The Lazy Networker

Neighbour table Topology table (all possible paths to the destination) Routing Table (Best path) Advertised distance (distance between the local router and the next-hop router) Feasible distance (sum of these ADs costs is referred to as the feasible distance (FD) Successor (Installed in the routing table)

EIGRP is a Cisco proprietary protocol. It has two AD values (Internal – 90, External – 170 ) Fast Convergence. Uses Dual (Diffusing update algorithm). No periodic Updates only triggered updates. Triggered updates only changes occurred. Consumes less bandwidth. Multiple network layer support (IPV4, IPV6). Use of multicast (224.0.0.10) and…

Update: frequency of updates, default 30 seconds. Invalid: seconds since a valid update was seen, to consider the route invalid and placing the route into hold down, default is 180 seconds, in other words six updates. After 180 seconds the route is considered invalid – unreachable (metric is 16). Hold…

Features of RIPv1 It is a universal protocol. Administrative Distance is 120. Hop count is used as the metric for path selection. The maximum hop count is 15, so it supports maximum 16 routers per interface. Routing updates are broadcast every 30 seconds by default. Because it is a distance…
