Q

2 steps to have EIGRP use a key chain in authentication

A
  1. Under a given interface, set up authentication for the routing protocol.
  2. Staying under that same interface, bind the key-chain that will be used to the auth line.

26
Syntax to bind a dlci to an interface

27
Command to show InArp data
show frame-relay map
28
What is the successor?
The successor is the path that has the best metric.
29
What is the Feasible Distance?
The metric of a given route from the current router's point of view.
30
What is the Reported Distance?
The metric of a given route from the neighbor's point of view.
31
If a path meets the feasibility condition, but does not fall within variance parameters, what happens to it?
It is held in reserve as a feasible successor, one which may take over if the current successor fails.
32
What is the feasibility condition?
The reported distance of a path must be less than the FD of the path on the current router.
33
What happens to a path who's FD falls within variance parameters but does not meet the feasibility condition?
It's not installed in the routing table, nor will it be a Feasible Successor
34
How does a router determine if a path can be a Feasible Successor?
If the path's RD is less that the FD, it will be a Feasible Successor.
35
When you show the routing table, what letter signifies that route was learned via EIGRP?
D
36
In the 4 layer TCP/IP model, what are the names of the layers?
1. Application 2. Transport 3. Internet 4. Link
37
In the 5 layer TCP/IP model, what are the names of the layers?
1. Application 2. Transport 3. Network 4. Data Link 5. Physical
38
What does the Application layer in the TCP model map to in the OSI model?
Application Presentation Session
39
What does the Transport layer in the TCP model map to in the OSI model?
Transport
40
What does the Internet or Network layer in the TCP model map to in the OSI model?
Network
41
What does the Link layer in the TCP model map to in the OSI model?
Data Link | Physical
42
What are the first 4 syslog level names, starting with level 0?
0 - Emergency 1 - Alert 2 - Critical 3 - Error
43
What are the last 4 syslog level names?
4 - Warning 5 - Notification 6 - Informational 7 - Debugging
44
What severity levels will be sent to the syslog server if "logging trap 4" is configured?
``` Levels 0 - 4 Emergency Alert Critical Error Warning ```
45
If "logging trap informational" is set, what numerical levels will be set to syslog?
0 - 6
46
What does PPP stand for?
Point to Point Protocol
47
What are 2 PPP control protocols?
LCP | NCP
48
What do NCP and LCP stand for?
Network Control Protocols | Link Control Protocol
49
What's a glaring difference between NCP and LCP?
LCP is a single protocol, whereas NCP is a suite of protocols that are each specific to a Layer 3 protocol.
50
4 features of PPP LCP
1. Loop detection 2. Error detection 3. Multilink support 4. Authentication
51
What 2 types of authentication are supported by PPP?
PAP | CHAP
52
What do PAP and CHAP stand for?
Password Authentication Protocol | Challenge Handshake Authentication Protocol
53
Which PPP auth protocol sends a password in clear text?
PAP
54
What are the 3 steps of a successful CHAP authenticatoin?
1. Authenticator sends challenge packet. 2. Caller hashes password etc and sends back hashed value. 3. Authenticator compares submitted value to their own hashed value, and if they match it allows the caller in.
55
Command to set PPP on a serial interface
conf t int s1/0 encapsulation ppp
56
2 general steps to have a PPP link use PAP or CHAP
1. Configure the username/password for the calling router. | 2. Set the serial link to use PPP PAP
57
What will the state of a serial link be if PPP authentication fails?
Up/down
58
Syntax to set a username/pass for use in PPP authentication
username *caller hostname* password *password*
59
Syntax to have a serial interface use CHAP
conf t int s1/0 ppp authentication chap
60
2 useful debug commands for PPP
debug ppp authentication | debug ppp negotiation
