What is a core router?
A core router is a router that switches packets at optimum speed on the backbone of a network.
What is route summarization?
Route summarization is the process of using a single network address and mask (or prefix) to represent multiple networks or subnetworks.
What is route redistribution?
Route redistribution is the process of importing routes learned from one routing protocol into a different routing protocol or separate routing process.
What is full mesh?
Full mesh is a network in which every router maintains a direct connection to every other router.
What Cisco series routers are used at the access layer?
The access layer uses the 2600, 2500, 1700 and 1600 Cisco series routers.
What is scalability?
Scalability is the capability to grow and adapt without major redesign or reinstallation.
What does FIFO stand for?
FIFO stands for first in, first out queuing.
What does DDR stand for?
Dial on demand routing.
What is custom queuing?
Custom queuing is a method of queuing that is used to guarantee bandwidth for traffic by assigning queue space to each protocol.
What is CEF (Cisco Express Forwarding)?
Cisco Express Forwarding is a switching mode on a Cisco router that uses a Forwarding Information Base (FIB) lookup table that contains all known routes that exist in the routing table. CEF eliminates route cache maintenance and can switch traffic more efficiently than typical demand-caching schemes.
What is WFQ (weighted fair queuing)?
WFQ (Weighted fair queuing) is a queuing method that prioritizes interactive traffic over file transfers to ensure satisfactory response time for common user applications.
What is compression?
Compression is the running of a data set through an algorithm that reduces the space required to store the data set or the bandwidth required to transmit the data set.the
What is priority queuing?
Priority queuing is a queuing strategy in which frames in an interface output queue are prioritized based on various characteristics, such as packet size and protocol type.
What is unequal-cost load balancing?
Unequal-cost load balancing is the distribution of traffic load across multiple links that do not have the same cost or metric value.
What is a policy?
A policy is an approach to handling certain kinds of traffic, including routing updates, route summarizes, VLAN traffic, and address aggregation.
What is an Access router?
An Access router is a router that provides network access to LAN hosts and remote users.
What is DDR (Dial-on-demand routing)?
Dial-on-demand routing is a technique by which a router can dynamically initiate and close circuit switched sessions as transmitting end stations need them.
What does CEF stand for?
Cisco Express Forwarding
What is a three-layer network design model?
A three-layer network design model is a hierarchical model for scalable network design that consists of core, distribution, and access layers
What is fast switching?
Fast switching is a switching mode on a Cisco router that uses a high-speed route cache after an initial routing table lookup.
What is a distribution router?
A distribution router is a router that separates the access layer and core layer by establishing routing and security policies.
What is equal-cost load balancing?
Equal-cost load balancing is distribution of traffic load across multiple links of the same cost or metric value.
What is FIFO (first in, first out)queuing?
(First in, first out)FIFO queuing is a simple queuing strategy that queues packets for transmission according to the order in which they arrive.
What is queuing?
Queuing is the process that the router uses to schedule packets for transmission during periods of congestion.
What Cisco series routers are used at the distribution layer?
The distribution layer uses the 3600, 4500, and 4000 Cisco series routers.
What does WFQ stand for?
WFQ stands for weighted fair queuing.
What is process switiching?
Process switching is a process that involves the switching of entire packets to the router CPU, where they are repackaged for delivery to or from a WAN interface, with the router making a route selection for each packet. Process switching is the most resource-intensive operation that the CPI performs.
What Cisco series routers are used at the core layer?
The core layer uses the 12000, 7500, 7200, and 7000 Cisco series routers.
What is an incremental routing update?
An incremental routing update is a routing update that contains information only about routes that have changed.
What Cisco series routers are used at the access layer?
The access layer uses the 2600, 2500, 1700 and 1600 Cisco series routers.
What is packet switching on a router?
Packet switching on a router is the process of receiving a packet on one interface and then forwarding it out another interface.
What is tunneling?
Tunneling is an architecture that is designed to provide the services necessary to implement any standard point-to-point encapsulation scheme.
