|
Enterprise Campus
|
|
|
Which Enterprise Composite Network Model area aggregates connectivity from the various elements at the edge of the enterprise network, including to remote locations, the Internet , and remote users.
|
Enterprise Edge
|
|
|
Which Enterprise Composite Network Model area is not implemented by the organization; instead, it is included to represent connectivity to service providers such as Internet service providers (ISPs), WAN providers, and the public switched telephone network (PSTN).
|
Service Provider Edge
|
|
|
What network device forwards packets towards destination networks?
|
router
|
|
|
The time it takes for all routers in a network to agree on the new topology.
|
convergence time
|
|
|
When is a network converged?
|
When routing tables on all routers in the network are synchronized and contain a route to all destination networks.
|
|
|
What is the command to configure a static route?
|
ip route
|
|
|
How is a static default route configured?
|
Use the normal ip route command, but with the destination network and its subnet mask both set to 0.0.0.0.
|
|
|
What are the 5 dynamic routing protocols?
|
RIP (1 & 2), EIGRP, IS-IS, OSPF, BGP
|
|
|
BGP requires its neighbors to be _________.
|
statically configured
|
|
|
What uses the Cisco Discovery Protocol (CDP) to carry network information between spoke (stub) routers and a hub router?
|
ODR (on demand routing)
|
|
|
What provides IP routing information with minimal overhead compared to a dynamic routing protocol and requires less manual configuration than static routes?
|
ODR (on demand routing)
|
|
|
How do you configure ODR on a hub router?
|
"router odr" global configuration command
|
|
|
How often are CDP updates sent out by default?
|
60 seconds
|
|
|
How are CDP times adjusted?
|
"cdp timer" global configuration command
|
|
|
How can CDP settings be verified?
|
show cdp interface
|
|
|
When using this type of routing protocol, all the routers periodically send their routing tables (or a portion of their tables) to only their neighboring routers.
|
distance vector routing protocol
|
|
|
When using this type of routing protocol, each of the routers sends the state of its own interfaces (its links) to all other routers (or to all routers in a part of the network, known as an area) only when there is a change.
|
link state routing protocol
|
|
|
Routing updates sent by a _________ routing protocol do not include the subnet mask.
|
classful
|
|
|
Routing updates sent by a ________ routing protocol include the subnet mask.
|
classless
|
|
|
______________ routing protocols do not support VLSM.
|
classful
|
|
|
__________ subnets are subnets of the same major network that are separated by a different major network.
|
discontiguous
|
|
|
_________ protocols automatically summarize at network boundaries.
|
classful
|
|
|
How can you turn off route summarization?
|
"no auto-summary" router configuration command
|
|
|
____ is a classful distance vector routing protocol that does not send the subnet mask in its updates.
|
RIP v1
|
|
|
RIPv2 uses the _________ multicast address to advertise to other RIPv2 routers.
|
224.0.0.9
|
|
|
RIP can fit up to __ networks in each update, and updates are dispatched every __ seconds.
|
25, 30
|
|
|
To activate the RIP process (version 1 by default), what command do you use?
|
"router rip" global configuration command
|
|
|
How do you control the version of RIP on each interface?
|
"ip rip {send | receive} version { 1 | 2 | 1 2 }" interface configuration command
|
|
|
How can you summarize RIP routes on nonclassful boundaries?
|
1. Turn off automatic summarization using the "no auto-summary" router configuration command.
2. Use the "ip summary-address rip *network-number* *mask*" interface configuration command to define a network number and mask that meet the particular summarization requirement. |
|
|
What command allows you to view the IP routing table?
|
show ip route
|
|
|
What command displays summary address entries in the RIP routing database if relevant child routes are being summarized?
|
show ip rip database
