How does OSPF select a Router ID?

Back 24

1. The value of the router-id OSPF subcommand / 2. The highest active loopback address / 3. The highest nonloopback address

Front 25

LSU

Back 25

Link State Update packet (used for sending Link State Updates in OSPF)

Front 26

Steps to becoming OSPF Neighbors

Back 26

DOWN - the routers do not know about each other / INIT - an initial HELLO has made the routers aware of each other / 2-WAY - The routers believe that all pertinent information matches and that they should become neighbors and exchange LSDBs / FULL - Process complete, LSDBs match

Front 27

OSPF Hello Interval

Back 27

(GET A NUMBER) how often OSPF neighbors send HELLO packets to each other

Front 28

OSPF Dead Interval

Back 28

4 x the Hello Interval, how long an OSPF router will go without a HELLO before declaring a neighbor down

Front 29

What two circumstances causes LSAs to be sent in OSPF?

Back 29

LSAs are sent every 30 minutes regardless of changes, LSAs are also sent with any topology change.

Front 30

Designated Router & Backup Designated Router

Back 30

In OSPF on a multi-access (Ethernet) network, one router is selected as the DR, which forms full adjacencies with all other routers on the multi-access network segment. The BDR exists only to take over if the DR fails. Routers in the multi-access segment will not form full adjacencies with any routers except the DR.

Front 31

What must match for OSPF routers to become neighbors?

Back 31

Hello & Dead Timers

Front 32

ABR

Back 32

Area Border Router - An OSPF router that has interfaces connected to the backbone area (Area 0) and at least one other area

Front 33

Backbone Router

Back 33

An OSPF router that exists entirely in Area 0

Front 34

Internal Router

Back 34

An OSPF router that exists entirely in an area other than Area 0

Front 35

Area

Back 35

A set of routers and links that share an LSDB

Front 43

EIGRP Convergence Process

Back 43

1. Routers exchange Hellos to establish adjacency and update neighbor tables / 2. Routers exchange full routing info and update topology tables / 3. Routers choose best routes and update the routing table / 4. When topology changes occur, routers respond with partial updates and reconverge on new info

Front 44

Components of the EIGRP Composite Metric

Back 44

(Bandwidth), (Delay) reliability and load () = on by default

Front 45

Successor

Back 45

Neighboring router used for packet forwarding (least cost router to destination net)

Front 46

Feasible Distance

Back 46

The lowest calculated metric to reach the destination net

Front 47

Feasible Successor

Back 47

A neighbor that has a loop free backup path to the same net as the successor, while satisfying the Feasibility Condition

Front 48

Advertised or Reported Distance

Back 48

The feasible distance reported by a neighbor

Front 49

Feasibility Condition

Back 49

A neighbor's Reported Distance must be less than the local router's FD to same destination

Front 50

EIGRP Active State

Back 50

A network is in Active state when there are no feasible successor routes available and the router is ACTIVELY querying neighbors seeking a route.

Back 59

encapsulation dot1q [native vlan]

Front 60

What OSPF settings must match for an OPSF adjacency to form?

Back 60

The interfaces are not on the same network, OSPF network types do not match, OSPF Hello/Dead timers do not match,Interface to neighbor is passive,missing or incorrect OSPF network command, Authentication misconfigured

Front 61

T1 Bandwidth

Back 61

1.544 Mbps

Front 62

From the "show frame-relay pvc" command, whar are the three likely PVC STATUS messages and what do they mean?

Back 62

+ ACTIVE: the PVC is operational and can transmit data.

+ INACTIVE: the connection from the local router to the switch is working, but the connection to the remote router is not available

+ DELETED: the PVC is not present and no LMI information is being received from the Frame Relay switch

Front 63

Back 63

Hot Standby Router Protocol

All routers are part of a "Standby Group", besides the physical IP of the interface, a virtual IP is also configured. All routers in the group must have the same virtual IP.
