00:00:07,470 --> 00:00:11,550
Hello and welcome
to IS-IS overview.

4
00:00:11,550 --> 00:00:14,580
In this skill, we're
going to jump in and take

5
00:00:14,580 --> 00:00:18,600
a look at some of the
basic attributes of IS-IS

6
00:00:18,600 --> 00:00:20,830
as a routing protocol.

7
00:00:20,830 --> 00:00:23,970
Now one thing that's a
little bit unique about IS-IS

8
00:00:23,970 --> 00:00:26,620
is it does support
multiple protocols.

9
00:00:26,620 --> 00:00:28,360
So we'll be taking
a look at that.

10
00:00:28,360 --> 00:00:30,810
We'll also take a look
at how it's actually

11
00:00:30,810 --> 00:00:36,120
fairly similar in a lot of
the ways it operates to OSPF.

12
00:00:36,120 --> 00:00:38,520
It is a link-state
routing protocol,

13
00:00:38,520 --> 00:00:41,280
it supports areas, and so on.

14
00:00:41,280 --> 00:00:44,310
We'll dig a little bit
deeper into that hierarchy.

15
00:00:44,310 --> 00:00:46,290
And then, we'll take
a look at things

16
00:00:46,290 --> 00:00:50,440
like how it performs its
best path selection process.

17
00:00:50,440 --> 00:00:53,770
So we have a lot of stuff
to look at in this skill,

18
00:00:53,770 --> 00:00:59,220
so join me as we jump in and
get a basic overview of IS-IS.

19
00:00:59,220 --> 00:01:02,540
I'll see you in the next video.
