Validation Framework

Test Bed

You are free to choose the integration either directly at the core switch or with a pair of dedicated service block switches. Therefore, we used the network architectures shown in Figure 1 and in this JVDE.

Figure 1: 5-Stage IP-Clos, ERB or CRB Fabric - No Dedicated Service Block 5-Stage IP-Clos, ERB or CRB Fabric - No Dedicated Service Block

Figure 2: 5-Stage IP-Clos, ERB, or CRB Fabric with Dedicated Service Blocks 5-Stage IP-Clos, ERB, or CRB Fabric with Dedicated Service Blocks

In the first case, the WAN routers directly attached to the core routers were Juniper MX routers. In the second case the WAN routers attached to the dedicated block of service switches were Juniper SRX Series Firewalls in HA cluster mode.

The fabric type can be either ERB or IP Clos because in those fabrics the core router only performs a forwarding function. Due to our Juniper Mist portal configuration, the L2 or L3 Junos configuration is added as needed so we can easily document the differences in the configurations.
