The distance vector algorithm has the following properties s

The distance vector algorithm has the following properties (select all that apply): Hierarchically scalable to large networks Convergence is slower than Link State algorithms Routers broadcast routing updates regarding its neighbors to all nodes in the AS Routers send their routing table to their neighbors every 30 seconds In routing with BGP among AS\'s, which of the following Issues dominates: number of AS\'s traversed current congestion levels in the AS\'s policy geographical distance between AS\'s

Solution

2.> The distance vector routing protocol are very simple & efficient for small networks.They have poor convergence properties thus slower than link state protocol. Also, in case of distance vector protocol, routers dont broadcast rather they share their routing table to only neighbours.
     answer : B, D

3> According to RFC 1266 for BGP protocol, in order to reduce the drop of BGP packets we need to take two measures. 1> reduce the congestion 2> setting proper policies on the routers.
     answer : B, C
