What would be considered a Layer 3 Function or Service?
Logical Addressing
What Layer of the OSI Reference Model does “Routing” occur?
Layer 3 (Network)
What routing protocol is used to route traffic on the internet?
BGP4/ MP-BGP
Note: BGP stands for “Border Gateway Protocol” and “MP” stands for “Multiprotocol”
What are the (2) forms of routing entries?
Dynamic and Static entries
What is a “Hop Count?”
A routing metric that indicates the number of intermediary routers a packet must pass through to reach the network of its destination address
What is “Convergence?”
The condition that exists when the routing tables of neighboring routers are in synchronization?
What is “Load Balancing?”
The action in which a router divides and forwards incoming or outbound message traffic to multiple links
What are the (2) types of “Dynamic Routing Protocols?”
Link-State; and
Distance-Vector
What is a “Maximum Transmission Unit?”
The length of the longest data unit that can be transmitted on an available link
What distance-vector routing protocol bases its routing decisions solely on “hop count?”
RIPv2/RIPng
Note: “RIP” stands for “Routing Information Protocol”
What technique is used on networks to prevent a Layer 2 network loop?
Spanning Tree
True or False.
VRRP is a routing protocol that can be used to configure resilience on a network.
TRUE.
