因於本來的 RIP、IGP 無法處理大型網路,所以才有 OSPF、IGRP、EIGRP 的出現。在處理大型的互聯網路中,OSPF 整體表現比 RIP 好很多。
OSPF 與 IGRP 不同之處在於,前者支援 VLSM (Variable Length Subnet Mask)。
- Router:
-
Speed of Convergence Optimization using Parallel Computing. 使用平行運算方式處理路徑問題。
-
Support VLSM, 支援可變動長度子網路遮罩。
-
Network Reachability, 網路觸及範圍:
-
RIP: max: 15 hops
-
OSPF: without limitation
-
-
Method for Path Selection, 路徑選擇方式:
-
RIP: hop count
-
OSPF: cost == connection speed
-
-
Usage of Band Width, 佔用頻寬
- RIP: Broadcast / 30 sec

* OSPF: Broadcast while changed occurs
