IS-IS - IS-IS Operation over Different Network Types - IS-IS Operations over Point-to-point Links
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
What is the command to configure IS-IS point-to-point three-way-handshake method by Cisco?
What are the TLV's augumented (uitgebreid) fields to carry additional information about the neighbor's identity and interface?
-Neighbor System ID
-Neighbor Extended Local Circuit ID (interface)
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
