CCNA-200-301- aaa5GITTC-Unlocked

 It is effectively loop-free, having a maximum hop metric of 65,535

 It can load balance network traffic between multiple paths of the same metric value

 It supports authentication using passwords and other methods

 It converges quicker than RIP since routing updates are sent immediately instead of

periodically

 It uses less bandwidth since transmission take place only when routing changes occur

 It supports the logical grouping of network segments into areas (see the "Autonomous

System" section below)

 It announces routes outside of an autonomous system within the autonomous system so

that it can calculate costs to reach outside networks

 Since OSPF announces subnet masks, it supports CIDR , VLSM (Variable Length

Subnetting), Supernetting (used to aggregate Class C networks) and non-contiguous

network segments
