Juniper Apstra Demo: Revert Network Change with Time Voyager

0:01 [Music]

0:07 appstr time voyager function is a

0:09 control z function that allows you to

0:11 restore the network to a previously

0:13 known good state

0:15 appstr keeps track of all changes and

0:17 its graph database

0:19 the time voyager is our way to navigate

0:22 through changes on a fabric-wide basis

0:26 in this case somebody removed the green

0:28 routing zone and green vlan

0:31 and we can see that leads to

0:33 connectivity loss for this individual

0:35 server

0:38 if we do a ping we can see that the ping

0:41 fails

0:47 this is because the underlying networks

0:50 have been removed from the fabric if we

0:52 go to time voyager we can see that on

0:54 january 13th somebody removed them so i

0:58 want to roll back to the previous estate

1:00 that the network was back in january

1:01 12th when the green vxlan was added

1:05 all we need to do is click revert and

1:07 the changes that we make are always

1:09 pre-validated before we push out to

1:11 production network

1:13 and they show up in the uncommitted tab

1:16 when it turns yellow it means that there

1:18 is something for us to review

1:21 so we go there and commit the change

1:24 once we commit the change it will take

1:26 that information and push it down to the

1:28 devices and our network will be restored

1:31 to a previously known good state

1:35 so let's commit that

1:44 and now that the changes are committed

1:46 we can go back to our servers and now we

1:49 can see that the networks are back and

1:51 the servers can reach each other again

1:53 via ping

2:09 we take a look at our configuration we

2:11 can see that the green network is there

2:16 the green routing zone is also back

2:19 and the connectivity template that

2:21 applies network to the individual ports

2:23 is restored
