6 important questions on IS-IS - IS-IS Operation over Different Network Types - IS-IS Operations over Point-to-point Links
Describe the IS-IS three way handshake?
Router A can hear Router B
Uncertain Router B can hear Router A
2. So Router A sends now an IIH to Router B with adjacency three way state set to initializing
Certain Router B can hear Router A
3. So Router B sends now an IIH with the adjancey three way set to up
Router A is now als certain that bidirectional communication is possible
SO Router A send IIH with Adjancency three way state up
