Video Description

Standard Access Lists Lab In this lab, we demonstrate how the Standard Access List type functions and what specific components enable its functionality. We begin with a demonstration on how to create a Standard Access List, we ping to confirm specific loop-back address then demonstrate how this process works when a specific host is excluded by design and should not be included in the transport output from the newly created Standard Access List.

Video Transcription

00:04
the first order of business. I am going to
00:08
show you how to create standard access lists.
00:12
So
00:13
what I have done already is I have added network 30
00:18
which were the three Lou backs
00:20
30.10
00:22
dot a dot a 30 that tend on 9.9 30 10 not 10 not 10. The three Lou backs that we had created previously on router to one. I went ahead and added Those two are SPF. So here you see my network statement. This one network statement takes care of all three loop axe. I said network 30 that $10.00
00:42
since the second and third octave changed.
00:44
I used to five fives in the second and third octet to tell the router I don't care what value values you let through for the third and fourth octet. The first and second octet match. Exactly. Let me show you those interfaces again. Show interfaces
01:02
show
01:03
I p interface breathe.
01:07
And these were the Lou backs we had previously created on Router 10 for r E i g R P manual summarize Ishan. I'm just going to use them for a different purpose.
01:17
So you see, router to
01:19
already has these in its routing. Tomo shou id be route.
01:25
Here they are.
01:26
The three Lou backs on router to one. I'm going to see if I can reach them from Host Tree. So I go to the command prompt
01:36
on host three.
01:38
And I say paying 30 dot Tenn 30.0.8 at eight.
01:47
And it should reply
01:49
the first request timed out for the AARP.
01:52
Uh, requesting reply process 30 dot Tenn 30.0.9 dot nine.
01:57
And I have a reply from 9.9 and
02:00
cannot 10.
02:04
And I'm getting replies from $30. 10. 10 10.
02:07
Now I'm going to create an access list on router to
02:12
so that
02:13
host tree should be about should be able not about Abel
02:21
trooping 30 dot Tenn dot a 30.0.0.8
02:23
and all addresses on the network on network to a one.
02:29
So host three should be able to ping
02:34
this loop back address on Lee on Router to a one
02:38
and all addresses on the 200 network, which means studios, you know, 10 address on router to a one which is 202 102 102
02:47
and
02:50
the serial zeroes, you know, zero address show I P I N t brief and the serial 000 address on router one.
03:00
Host tree should not be able to paying anything else.
