Chapter 7 Routing Flashcards
what is port triggering
will open an alternate assigned port when the intital port is contacted
What is a multilayer switch
A switch that works on multiple layers
What happens when you enable DMZ on a router
places a device outside the protection of that router
What layer of the OSI model does a multilayer switch work on
Layer 3 - Network layer
What is router convergence
When all routers have the same info on their routing tables
What is a hop count
The number of routers it took to get to a certain network id
What is (MTU) Maximum Transmission Unit
How much data can you carry
How do dynamic protocols determine routes
By metrics which are either distance vector or link state
What are the two types of dynamic routing protocols
IGP (Interior gateway protocol)
EGP (Exterior gateway protocol )
What EGP protocol is used for inter-autonomous system routing
BGP
What is RIP (Routing Information Protocol )
A distance vector protocol that uses hop count to determine routes
When does RIP only work
When the network is a classful network only
How many hop counts can be done with RIP
a maximum if 15 hop counts
What type of protocol is OSPF (Open Shortest Path First)
A link state protocol
What is BGP (Bridge Gateway Protocol)
Hybrid protocol, primary protocol for the internet, based around the concept of autonomous systems
