| What is a loop back interface? |
|
Definition
| Software-only interface used to emulate an interface. |
|
|
Term
| What is a null interface and how is it represented? |
|
Definition
| A null interface is an interface which does not have a physical existence but can be used to designate a route as "null0" Remember that a static route requires a valid exit interface. Using a null interface allows a router to represent a static route in RIP. |

|
Term
| Where is "redistribute static" declared and what does it do? |
|
Definition
router "routing protocol" ie rip
R1(config-router)# redistribute static
This command allows static routes to be sent via routing updates via dynamic routing protocols. |

Term
| What is a boundary router? |
|
Definition
| A router that sits on the edge of two discontiguous classful networks. It can also be a router which sits at the edge of two different networks that have different routing protocols. |
|
|
Term
| What message does RIPv1 send when a static route of 192.168.0.0/16 is statically configured and redistribute static is also configured on the router? |
|
Definition
| The 192.168.0.0/16 route is not sent with RIPv1 updates because the route is less than the classful mask. |
|
|
Term
| What four pieces of data are different in a RIPv2 update vs an RIPv1 update? |
|
Definition
| Subnet mask, next hop address, version and route tag |
|
|
Term
| By default what does a router configured with RIPv2 do with an update it receives via RIPv1? What can be done to change this action? |
|
Definition
RIPv2 ignores RIPv1 updates
"ip rip send" & "ip rip receive" can be used to force compatibility between different versions |

Term
What address is used to send RIPv1 updates?
What address is used to send RIPv2 updates? |
|
Definition
RIPv1 -- Broadcast
RIPv2 -- Multicast |
|
|
Term
| Four ways to verify and troubleshoot RIPv2. Starting with the basics -- |
|
Definition
1. Make sure that all the links are up
2. Check the cabling
3. Make sure the correct IP address and subnet mask are on each interface
4. remove any configuration commands that are no longer necessary or have been replace by other commands. |

|
Term
| If a network is missing from the routing table, it is often because an interface is down or incorrectly configured. Which command can give you thing information? |
|
Definition
|
|
Term
| Command which tells whether RIP is enabled, the version of RIP, status of automatic network summarization, and the networks which were included in the network statements |
