Module G3 PE - IP Routing Flashcards
Standard used in order to pass IP traffic across the internet.
ip routing
This holds a higher precedence than dynamically assigned routes
static route
Which is not an advantage for static routes?
- On larger networks static routing is very easy to set up
- System Administrator has full control over all routing behavior on the network
- On smaller networks static routing is very easy to set up
- CPU does not have heavy workload due to no traffic that has to be passed to other routers
On larger networks static routing is very easy to set up
what is route summarization also called
super-netting (aggregation)
____ Can reduce the number of routes that a router must maintain in its routing table
route summarization
A default route is also called what
gateway of last resort
Route that takes effect when no other route is available for an IP destination address. (Router is setup)

Default route
what will occur to packets not found in an address table and a Router is not setup?

What is a standardized exterior gateway protocol that exchanges routing and reachability information between autonomous systems on the internet?
BGP (Border Gateway Protocol)
A routing protocol between different Autonomous systems is called what?
EBGP (External Border Gateway Protocol)
______ does not offer fault tolerance
static routes
What measures the number of routes that packet travels through RIPv1 and RIPv2?
hop count
If a router cannot find the right route what is taken?
default route
RIPng sends updates on what port?
521
Distance vector involves two things, what are they?
distance and vector
To set a default route, what command do you use?
ip route
What does OSPF stand for?
Open Shortest Path First
RIPv1 is known as?
classful routing
What type of routing lets routers select the paths?
dynamic
What is the default distance for EGP?
140
What is the metric of the best route to reach a network called?
feasible distance
What chooses the routing path based on which takes the least time EIGRP
delay
What command would you input in order to display the IP of the OSPF neighbor?
sh ip ospf neighbor
What is the main limitation of RIP
maximum hop count of 15
In OSPF, if a neighbor received a hello and responded with a hello, what is this state?
2 way state
command used to assign a default route
- ip
- ip route
- route
- default
- standard out
ip route
provide a valid command to assign a default route to another (198.150.17.1)
Dynamic route
____ uses specific protocols that can optimize data routing.
dynamic routing
Which form of routing has more automatic configuration from the routers to select the best route?
- Active Configuration Routing
- Score Vectored Routing
- Dynamic route
- Static Route
- Artificial Imprint
- Passive Configuration Routing
Dynamic route
Which is not a feature of dynamic routing
- Identify other networks
- role based network segregation/aggregation
- Analyzing effiecient ways to get to destination networks
- updates on current routing information
- finds alternative paths to destination
role based network segregation/aggregation
_____ are routing protocols that exchange routing information with other routers within a single autonomous system
Interior Gateway Protocols
A routing protocol that uses the number of hops from on location to the next as a form of scoring to determine the best route?
RIP
What form of routing protocol is susceptible to looping
distance vector
Which more accurately defines an autonomous system (AS)
- One network or a collection of networks under the control of one enterprise.
- Self-operating machine, or control mechanism designed to automatically follow a properations, or respond to predetermined instructions.
- list of the IP address space that the AS controls, plus a list of the other ASes to which it connects.
- A connection endpoint that connects with each other computers and exchange network traffic (data packets) through a process called peering.
One network or a collection of networks under the control of one enterprise.
Read carefully, Which is not a Distance vector routing protocol
- ElGRP ( l = lowercase L )
- RIPv1
- EIGRP ( I = uppercase i)
- RIPv2
