Advanced OSPF
OSPF is an industry-standard routing protocol developed by the Internet Engineering Taskforce (IETF) as a replacement for legacy routing protocols that did not scale well in large environments. OSPF supports the following features:
Variable-length subnet masks (VLSM).
The use of areas to minimize Central Processing Unit (CPU) and memory requirements.
A simple cost metric that you can manipulate to support up to six equal cost paths. The number of paths is limited only by the Internet Operating System (IOS).
The use of authentication to ensure OSPF updates are secure and the use of multicast updates to conserve bandwidth.
Faster convergence times ensuring updates and changes are propagated across the network.
No limitation of network ...
