What are the minimum four fields that a routing table should have?
Interface
NetID
Metric
Next-Hop
What are the two categories of routing protocols that interior gateway protocols can be divided into?
Link State Routing Protocols
Distance Vector Routing Protocols
If the sender is a host and wants to send a packet to another host on the same network, the logical address that must be mapped to a physical address is…
the destination IP address in the datagram header
If the sender is a host and wants to send a packet to another host on another network, the logical address that must be mapped to a physical address is…
The IP address of the router found in the routing table.
If the sender is a router that has received a datagram destined for a host on another network. the logical address that must be mapped to a physical address is…
The IP address of the gateway router found in the routing table
If the sender is a router that has received a datagram destined for a host on the same network. The logical address that must be mapped to a physical address is…
The destination IP address in the datagram header
An _______________________ is a collection of networks under a common administrative domain.
Autonomous System
In computer networking, _____________ route advertisment is a method of preventing routing loops in distance-vector routing protocols by prohibiting a router from advertising a route back into the interface from which that route was learned.
Split-Horizon
Routing within an autonomous system is referred to as ____________ routing.
Intra-domain
Routing between an autonomous system is referred to as ____________ routing
Inter-domain
The idea of IP address aggregation was designed to alleviate the increase in routing tables entries when using ________________.
Classless Adressing
________________ delivery of a packet occurs when the source and destination of the packet are located on the same physical network or when the delivery is between the last router and the destination host.
Direct
________________ delivery of a packet occurs when the destination host is not on the same network as the sending host
Indirect
A __________________ routing protocol requires that a router inform it’s neighbors of topology changes periodically and, in some cases, when a change is detected in the topology of a network.
Distance-vector
__________________ routing protocols require to inform all the nodes in a network of topology changes.
Link-State
The Routing Information Protocol (RIP) is an interior gateway routing protocol based on ____________ routing.
Distance Vector
The Open Shortest Path First (OSPF) protocol is an interior gateway routing protocol based on ________________ routing.
Link-State
The _________________ is the core routing protocol of the internet.
BGP ( is also an external gateway protocol )
________________ routing is used to send packets with a remote destination network not in the routing table to the next hop router.
Default
RIP used only __________________ to determine the best path to an internetwork.
Hop Count
