44
Q

What metric does rip use

45
Q

A

every 30 seconds

48
Q

A

max hop count is 15, anything more and the destination is unreachable

49
Q

A

default-information originate

50
Q

In order to establish a neighbor relationship using EIGRIP what must happen

A

routers send hello packets every couple of seconds

51

54
Q

what is feasible distance

A

best route to reach a destination

55
Q

what is reported distance

A

a route used by a neighboring router to reach the network

56
Q

What is the successor in EIGRP

A

Route with the best metric to reach a destination

57
Q

what is the feasible successor in eigrp

A

a backup path to reach that same destination that can be used immediately if the successor route fails.

58
Q

What protocol is used for EIGRP

59
Q

EIGRP Features

A

advanced distance vector routing protocol

classless routing protocol

supports VLSM (Variable Length Subnet Mask)

converges fast

supports multiple Network layer protocols (IPv4, IPv6, IPX, AppleTalk…)

uses multicast address of 224.0.0.10 for routing updates

sends partial routing updates

supports equal and unequal-cost load balancing

supports manual summarization on any router within a network

by default, uses bandwidth and delay to calculate its metric

Cisco proprietary

supports MD5 authentication

60

A

The last two numbers

61
Q

62
Q

How is the root switch selected?

A

the switch with the lowest switch id becomes the root switch.

63
Q

What consists of the switch’s id

A

the switch’s priority and the switch’s mac

64
Q
