Advantages of RIP, OSPF, and IS-IS
The biggest advantage of using RIP is that it is relatively simple to understand and to implement, and it has been the de facto routing standard for many years.
A limit of 15 hops between the source and destination networks
A large amount of bandwidth taken up by periodic broadcasts of the entire routing table
Slow convergence
Routing decisions based on hop count; no concept of link costs or delay
Flat networks; no concept of areas or boundaries
-
No limitation on hop count
-
Route updates multicast only when changes occur
-
Faster convergence
-
Support for load balancing to multiple routers based on the actual cost of the link
-
Support for hierarchical topologies where the network is divided into areas
The details of RIP are explained later in this chapter.
