Describes the differences and features of RIP and OSPF. A: ① the RIP Protocol is a traditional routing protocol and is suitable for small networks, however, the rapid development and rapid expansion of the current Internet network make the RIP Protocol unable to adapt to today's network. The OSPF protocol is developed when the Internet network expands rapidly. It overcomes many defects of the RIP Protocol. Www.2cto.com ② RIP is the distance vector routing protocol, and OSPF is the link state routing protocol. ③ RIP & OSPF Management Distance: 120 and 110 respectively. 1. A route entry of the RIP Protocol has 15 hops (gateway or router). If a route entry of the RIP network spans more than 15 hops (vro), the route entry considers the network to be inaccessible, OSPF has no limit on the number of routers that span. 2. The OSPF protocol supports the variable length Subnet Mask (VLSM), but RIP does not, which makes the RIP Protocol lack support for the current IP address and the flexibility of the Variable Length subnet mask. 3. the RIP Protocol broadcasts route tables on a regular basis instead of the actual network conditions, which is a great waste of network bandwidth resources, especially for large-scale Wan. The route broadcast update of OSPF only occurs when the route status changes. IP multicast is used to send the link status update information, which saves bandwidth. 4. The RIP network is a flat network with no layers on the network. OSPF establishes a hierarchical concept in the network. In the autonomous domain, network domains can be divided, so that the broadcast of routes is limited to a certain range, avoiding the waste of link relay resources. 5. OSPF uses an authorization mechanism during route broadcast to Ensure network security. The difference between the two shows the characteristics of the OSPF Protocol. Its advancement and complexity make it adapt to today's increasingly large Internet network and become the main Internet routing protocol.
