When you happen to be studying to pass the BSCI exam and earn your CCNP certification, you happen to be going to be introduced to ISIS. ISIS and OSPF are water ionizers each link-state protocols, but ISIS functions very differently from OSPF. You must master these facts in order to earn your CCNP.
A single of the main differences between OSPF and ISIS will be evident to you when you 1st begin your BSCI exam studies, and that is the terminology. ISIS makes patent pending use of terms that no other protocol you've studied to date utilizes, and learning these new terms is the initial step to BSCI and CCNP exam success.
Initial off, what does "IS" stand for in "ISIS"? It stands for "Intermediate Technique", which sounds like a group of routers. As opposed to Autonomous Systems, which are logical groups of routers, an Intermediate Technique is merely a single router. That is it.
You are going to also grow to be familiar with End Systems, referred to in ISIS as an "ES". The End Method is merely an finish host.
ISIS and OSPF both use the notion of areas, but ISIS takes a distinct approach to this idea. ISIS routers use 3 different varieties of routing levels, learn about tyent uce-9000t according to the region a router has been placed in. Level two routers are connected only to the backbone and serve as a transit device amongst non-backbone locations. Level 1 routers are completely internal to a non-backbone place.
ISIS makes use of both Level-1 and Level-2 Hellos, meaning that the two varieties of routers just mentioned cannot form an adjacency. Luckily for us, there is a middle ground, and that is the Level 1-two router. These routers connect non-backbone places to backbone locations. L1-L2 routers maintain two separate routing tables, one for L1 routing and one more for L2 routing. This is the default setting for a Cisco router, and L1-L2 routers can form adjacencies with each L1 and L2 routers.
Component of the challenge of mastering ISIS is getting employed to the differences amongst ISIS and OSPF. Keep studying the terminology, master one concept at a time, and soon you'll be a master of ISIS and a CCNP to boot!
