Hello, and welcome to
Implementing Segment Routing.

4
00:00:12,295 --> 00:00:15,640
In this skill, we're going
to jump into the command line

5
00:00:15,640 --> 00:00:18,980
and actually get segment
routing up and running.

6
00:00:18,980 --> 00:00:21,130
We're going to
start by configuring

7
00:00:21,130 --> 00:00:24,955
IS-IS, which is
currently our core IGP,

8
00:00:24,955 --> 00:00:27,010
to support segment routing.

9
00:00:27,010 --> 00:00:30,370
Then we're going to
configure our prefixes

10
00:00:30,370 --> 00:00:34,450
for the loopback interfaces
on each of our devices.

11
00:00:34,450 --> 00:00:36,520
Then we're going to
set up our routers

12
00:00:36,520 --> 00:00:40,240
to prefer using the
SR, or segment routing,

13
00:00:40,240 --> 00:00:43,450
labels over the LDP labels.

14
00:00:43,450 --> 00:00:48,760
Once that's working, we can
go ahead and remove LDP.

15
00:00:48,760 --> 00:00:51,910
It won't be needed in
our environment anymore.

16
00:00:51,910 --> 00:00:57,880
Finally, we're going to wrap up
by replacing IS-IS with OSPF,

17
00:00:57,880 --> 00:01:02,230
just in case OSPF doesn't
happen to be the IGP that you're

18
00:01:02,230 --> 00:01:04,459
using in your environment.

19
00:01:04,459 --> 00:01:07,040
So we have quite a
journey ahead of us.

20
00:01:07,040 --> 00:01:09,090
Let's go ahead and jump in.

21
00:01:09,090 --> 00:01:12,460
I'll see you in the next video.
