Explain the OSPF advantages? roger 14-February-2008 11:22:40 AMComments OSPF Information. OSPF Advantages. Low traffic overhead. OSPF is economical of network bandwidth on links between routers. Fast convergence. ... visit it www.ncat.co.uk/cisco-documents/ospf-information.htm Posted by waqasahmad 1. Faster convergence: OSPF network converges faster because routing changes are flooded immediately and computed in parallel. 2. Support for VLSM: OSPF supports VLSM. However, please note that RIP version2 also supports VLSM. 3. Network Reach ability: RIP networks are limited to 15 hops. On the other hand, OSPF has practically no reach ability limitation. 4. Metric: RIP uses only hop count for making routing decisions. This may lead to poor efficiency in some cases. For example, that a route is nearer but is very slow compared to another route with plenty of bandwidth available but few more hops away. OSPF uses "cost" metric to choose Best path. Cisco uses "bandwidth" as metric to choose best route. 5. Efficiency: RIP uses routing updates every 30 seconds. OSPF multicasts link-state updates and sends the updates only when there is a Change in the network status. Posted by dandelo |
