What aspects of IGRP have been
improved upon in EIGRP
3.1.1
Explain the differences in metrics
used by IGRP and EIGRP
3.1.1
How can an IGRP metric be converted
into a EIGRP metric?
3.1.1
How do hop counts differ between the
2 protocols?
3.1.1
What configuration must be the same
for IGRP and EIGRP to interoperate?
3.1.1
How does EIGRP treat routes learned
from IGRP
3.1.1
How does IGRP deal with external
routes?
3.1.2
What tables are maintained by EIGRP
3.1.2
Which is the most important table &
what is its function
3.1.2
Which command lets you view the
neighbouring routers?
3.1.2
How does the router learn about its
neighbours?
3.1.2
What is the hold time?
3.1.2
Where does the information in the
topology table originate?
3.1.2
Define feasible distance
3.1.2
What is a successor?
3.1.2
How many successor routes are
permitted?
3.1.2
What is a feasible successor
3.1.3
How does EIGRP differ from simple
distance vector routing protocols?
3.1.3
How does EIGRP conserve
bandwidth?
3.1.3
What is a bounded update?
3.1.3
Which routed protocols does EIGRP
support?
3.1.4
Describe the use of hello packets by
EIGRP
3.1.4
Why does EIGRP use RTP as its
transport layer protocol?
3.1.4
Describe DUAL
3.1.4
How does DUAL recalculate a route if
a route becomes unavailable?
3.1.5
What is the destination address of
EIGRP hello packets
3.1.5
What is the hold time?
3.1.5
Describe the different packets used by
EIGRP
3.2 Configuring EIGRP
3.2.1
Which command enables EIGRP
3.2.1
3.2.1
3.2.2
3.2.2
3.2.3
3.2.3
3.2.3
3.2.6
What step is important when
configuring serial links?
Which command is used?
Which additional command is
recommended by Cisco when
configuring EIGRP
Which command would you use so
that routes are not summarised at the
classful boundary?
Which command allows you to
manually enter a summary route?
Which command displays the eigrp
neighbour table?
Which command displays all the
feasible successors
Which command displays all routes
What happens when a link goes
down?
3.3 Troubleshooting Routing Protocols
3.3.1
What is the purpose of show
commands?
3.3.1
3.3.2
3.3.2
3.3.3
3.3.3.
3.3.3
3.3.4
3.3.5
3.3.5
What is the purpose of debug
commands?
What is a common problem
associated with RIP v1
Which command displays information
about RIP routing transactions
Which commands allow you to verify
IGRP configuration?
Which command allows you to verify
IGRP operation?
Which command allows you to view
routing update information?
Why should the hold-time value in a
show ip eigrp neighbors
command output normally be a value
of 10 to 15.
Which command allows you to
troubleshoot OSPF adjacency
problems?
What information is displayed by the
debug ip ospf events
command?
Show commands monitor installation and
normal behaviour. They show the status of
a router and display neighbouring routers.
They provide information about traffic,
error messages, troubleshooting data
RIP v1 does not support VLSM and does not
advertise routes using VLSM correctly
Router#debug ip rip
Router#debug show runningconfiguration
Router#show ip protocols
Router#show ip route
Router#debug ip igrp events
Hellos are sent every 5 seconds and expire
after 15.
Router#Show ip ospf neighbor
