Creating Tenant Networks

When initially installing the D-SBC SWe on OpenStack, the following networks must be created before instantiation:

• Management (MGT0) - used for OA&M access. SSH to the CLI, or browser access to the EMA is through management network.
• High-Availability (HA) - used for high-availability.

• Signaling/media (PKT0, PKT1) - used for SIP signaling and media. This includes SIP peers within the same network, SIP peers on a different networks within the same cloud, and peers on the public internet or in any network that requires exiting the cloud.

  Make sure all your NICs are physically plugged in (link light on) before spawning VM instance using qcow2 image. Otherwise, an incorrect port mapping may occur (logical to physical), and your SBC may not function properly.

      For IPv6 with DHCP enabled, ensure that subnet details IPv6 Address Configuration Mode is set to DHCPv6 stateful: Address discovered from OpenStack DHCP as demonstrated in the example screen capture below.

6. Repeat steps 3 through 6 to create HA, PKT0, and PKT1 networks.
