Part V. Initiate manual scale-out

  1. Execute scale-out workflow
  2. Modify Openstack route to new DAG instance
  3. Run test traffic

Step 1. Execute Scale-out workflow

VNF Manager can scale-out/in both DAG and Firewall layers. THis lab focuses on manual scale-out procedure for scaling out DAG layer.

To manually scale-out DAG layer, select Deployments –> dag_group_xxx Blueprint Expand menuIcon_deploy, click Gilan scale out group. Keep add_instances value of 1, and then click Execute.

Step 2. Modify openstack route

  1. Note newly created DAG layer BIG-IP pgw_net

  2. Select Project –> Network –> Routers and click on router1

    Open Static Routes tab and click on Delete Static Route to delete previously provisioned route. Click on Add Static Route Add the following route: 10.1.52.101/32 Next Hop <DAG layer BIG-IP pgw_net IP>

Step 3. Run test traffic

  1. Run test traffic through new DAG instance

Run test traffic

Note

This test is the same as in Part III Step 3 of this lab guide

  1. Point Jumphost Browser to new DAG BIG-IP instance .40 IP address and login to BIG-IP TMUI

  2. Navigate to Local Traffic –> Virtual Servers, then select f5dag partition from Partition: menu

  3. Select firewall_fastL4 VS and click on Statistics menu

    Traffic statistics will be visible in Traffic Details and Connections parts of Statistics screen. Note that due to the asymmetric routing, return traffic is NOT passing through the same DAG instance

Note

Other methods may be used to validate that the traffic is flowing through new DAG instances including running a tcpdump
