9.1.2. Hands-on Labs¶

Google deployment templates used to deploy the F5 BIG-IPs https://bit.ly/2LDV0Nw

Replace X with the number provided to you by the proctor

Connect as ssh -i userX userX@<instance-X> (<instance-X is an IP address that will be provided to you by the proctor; each student will get his/her own IP address)

9.1.2.1. Lab 1. Deploy 3-NIC F5 BIG-IP using deployment templates¶

curl -L https://bit.ly/2wwDu8i -o lab_f5_gdm_template.zip
unzip lab_f5_gdm_template.zip
nano f5-existing-stack-byol-3nic-changedmgmt-bigip.yaml

…and replace the license with the one provided by the proctor.

Replace X with the number provided to you by the proctor:

gcloud deployment-manager deployments create bigipuserXlab --config f5-existing-stack-byol-3nic-changedmgmt-bigip.yaml

Example for user 35

user35@instance-35:~$ gcloud deployment-manager deployments create bigipuser35lab --config f5-existing-stack-byol-3nic-changedmgmt-bigip.yaml

If you get an error saying that the deployment already exists , you just need to change the deployment name (“bigipuser35lab” in the example above).

Attention

Please just keep “bigipuserX” (replace X with the number assigned to you by the proctor) as part of the name so that we can quickly identify your instances.

After 2 minutes or so, search “compute engine instances” and select “Instances – Compute Engine” as shown below.

Filter by “userX” to find your 3-NIC F5 BIG-IP instance.

Example for user 35:

Click on the instance name (“bigipuser35lab” in the example above) to find the F5 BIG-IP’s management IP.

Write down the management IP of your 3-NIC F5 BIG-IP (screenshot above).

You can now connect to F5 BIG-IP management GUI using https:<F5 BIG-IP’s public IP in GCP> as admin. The password is the one set by the Google deployment template.

Short procedure to deploy F5 active/active and active/standby (not part of the hands-on labs)

Deploy 2 F5 BIG-IP using Google deployment templates

1a. Download the Google deployment templates
curl -L https://bit.ly/2wwDu8i -o lab_f5_gdm_template.zip
unzip lab_f5_gdm_template.zip
1b. Edit f5-existing-stack-byol-3nic-changedmgmt-bigip.yaml to fit your environment

1c. Deploy two F5 BIG-IPs
gcloud deployment-manager deployments create marcactive1 --config f5-existing-stack-byol-3nic-changedmgmt-bigip.yaml
gcloud deployment-manager deployments create marcactive2 --config f5-existing-stack-byol-3nic-changedmgmt-bigip.yaml

Get the F5 BIG-IPs’ IP addresses

gcloud compute instances list --filter="NAME~.*marcactive*"

NAME         ZONE        MACHINE_TYPE   PREEMPTIBLE  INTERNAL_IP                       EXTERNAL_IP                                 STATUS
marcactive1  us-west1-a  n1-standard-4               10.10.1.17,10.10.3.26,10.10.2.12  35.197.61.85,35.233.218.10,35.203.135.211   RUNNING
marcactive2  us-west1-a  n1-standard-4               10.10.1.18,10.10.3.27,10.10.2.13  35.227.174.29,35.227.157.60,104.198.105.51  RUNNING

The Google deployment template we used above creates F5 BIG-IPs with NICs in the following order: external, internal and management. So, 10.10.1.x is F5 BIG-IP external, 10.10.3.x is F5 BIG-IP internal, 10.10.2.x is F5 BIG-IP management

Connect to and configure the first F5 BIG-IP

ssh -i <private key> admin@35.203.135.211
bash
SOAPLicenseClient --basekey <license key>

At this point, you should see: [admin@marcactive1:Active:Standalone] ~ #

tmsh mv cm device bigip1 marcactive1.example.com
tmsh modify sys global-settings hostname marcactive1.example.com
tmsh modify cm device marcactive1.example.com configsync-ip 10.10.3.26
tmsh modify /net self self_internal allow-service all
tmsh save sys config

Attention

In a prod env, “allow custom” specifying just the ports you need would be best. These ports are shown at https://support.f5.com/csp/article/K13946

Extract:

Device group members should be able to communicate over ports 443, 4353, 1026 (UDP), and 22 (recommended). BIG-IP ASM requires the following additional Policy Sync TCP ports: 6123-6128. 6699 is also for communication channel between peers.

Connect to and configure the second F5 BIG-IP

ssh -i <private key> admin@104.198.105.51
bash
SOAPLicenseClient --basekey <license key>

At this point, you should see: [admin@marcactive2:Active:Standalone] ~ #

tmsh mv cm device bigip1 marcactive2.example.com
tmsh modify sys global-settings hostname marcactive2.example.com
tmsh modify cm device marcactive2.example.com configsync-ip 10.10.3.27
tmsh modify /net self self_internal allow-service all
tmsh save sys config

Create the trust domain

On the first F5 BIG-IP:

tmsh modify cm trust-domain /Common/Root add-device { device-ip 10.10.2.13 device-name marcactive2.example.com username admin password <password> ca-device true }

Attention

Escape any special characters in the password.

At this point, you should see:

[admin@marcactive1:Active:In Sync (Trust Domain Only)] ~ #
[admin@marcactive2:Active:In Sync (Trust Domain Only)] ~ #

NOTE: We use the BIG-IP management IP to create the trust domain (10.10.2.x in this example). The actual communication for failover and configsync uses the BIG-IP internal IP (10.10.3.x in this example).

Create the device group

On the first F5 BIG-IP:

tmsh create  cm device-group MarcSyncFailover devices add { marcactive1.example.com marcactive2.example.com } type sync-failover save-on-auto-sync true

Attention

The above command create a device group of type “sync-failover” as expected but doesn’t seem to set “sync type” = “automatic with incremental sync”. You can do this from the Configuration utility, navigate to Device Management > Device Groups, select the device group from the list, and change the Sync Type setting to Automatic with Incremental Sync).

At this point, you should see:

[admin@marcactive1:Active:Awaiting Initial Sync] ~ #
[admin@marcactive2:Active:Awaiting Initial Sync] ~ #

Start the initial sync

On the first F5 BIG-IP:

tmsh run cm config-sync to-group MarcSyncFailover

On both F5 BIG-IP, run

tmsh save sys config

At this point, you should see:

[admin@marcactive1:Active:In Sync] ~ #
[admin@marcactive2:Active:In Sync] ~ #

If you want to make this cluster active/standby :

On the first F5 BIG-IP:

tmsh modify /cm device marcactive1.example.com unicast-address {{ ip 10.10.3.26 }}
tmsh modify /cm device marcactive2.example.com unicast-address {{ ip 10.10.3.27 }}

If you want to make this cluster active/active again

On the first F5 BIG-IP:

tmsh modify /cm device marcactive1.example.com unicast-address none

On the second F5 BIG-IP:

tmsh modify /cm device marcactive2.example.com unicast-address none
