When you are 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 each link-state protocols, but ISIS works fairly differently from OSPF. You must master these particulars in order to earn your CCNP.
1 of the key differences in between OSPF and ISIS will be evident to you when you 1st start your BSCI exam studies, and that is the terminology. ISIS uses terms that no other protocol you have studied to date makes use of, and learning these new terms is the 1st step to BSCI and CCNP exam achievement.
Initial off, what does "IS" stand for in "ISIS"? It stands for "Intermediate Method", which sounds like a group of routers. As opposed to best water ionizer Autonomous Systems, which are logical groups of routers, an Intermediate System is just a single router. That is it.
You will also turn into familiar with End Systems, referred to in ISIS as an "ES". The End System is simply an finish host.
ISIS and OSPF each use the concept of locations, but ISIS requires a distinct method to this notion. ISIS routers use 3 different sorts of routing levels, 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 places. Level 1 routers are entirely internal to a non-backbone area.
