Enroll EP5G

EP5G Integration

This section explains how to register an Ericsson private 5G network as a network segment in Openstack. As shown in the figure, it is required that a VIP network accommodate the two network controller interfaces 10.30.111.20 and 10.30.111.21 connected to tenant switch ports te1/0/51 and te1/0/52. These interfaces should be able to reach the gateway on this subnet created by the router in Openstack i.e. 10.30.111.1.

Register the network segment

EXPECA Blazar is capable of enrolling network segments. By running the following command, we register network segment 300 with 2 baremetal ports and a gateway.

openstack reservation network create \
--network-type "vlan" \
--physical-network "physnet1" \
--segment "100" \
--extra segment_subnet="10.30.0.0/16" \
--extra segment_gateway="10.30.111.1" \
--extra vlan_id="100" \
--extra baremetal_ports='[{"name":"network_controller_1","ip-address":"10.30.111.20","binding-profile":{"local_link_information":[{"switch_id":"a0:f8:49:f7:89:d1","port_id":"te1/0/51","switch_info":"tenant-switch"}]}},{"name":"network_controller_2","ip-address":"10.30.111.21","binding-profile":{"local_link_information":[{"switch_id":"a0:f8:49:f7:89:d1","port_id":"te1/0/52","switch_info":"tenant-switch"}]}}]'

When user starts a lease with this network, Blazar creates the network segment 10.30.0.0/16 with the specified baremetal ports and the gateway 10.30.111.1. Inside the switch, VLAN 300 must be created with ports te1/0/51 and te1/0/52 subscribed to it.

Create the VIP router

EP5G does not work if you add servers to the VIP network. Packets only know the gateway. Therefore, after the lease starts, user must create a router with an interface attached to ep5g_vip network and chosen to be the gateway. Moreover, as mentioned in the image, an static route must be created on the router as well: ip route add 172.16.0.0/16 via 10.30.111.10. This router can attach to any other network that user desires. For internet connectivity, choose the router to connect to the external public network and enable SNAT.

Add a server behind vip network

You can create a backend network and add your compute hosts to be accessed by the end-nodes connected to the 5G network. For instance, you can create a backend network with the subnet 10.99.99.0/24 and add your compute host with 10.99.99.3/24 address as for the ip. Obviously you need to add an interface from the vip router to this network as for the gateway 10.99.99.1/24. Then, by adding a route on the compute host to the 5G terminals from the gateway, the connection is established. If you create a container the following lables could be used for such a setup:

networks.1.interface=enp4s0np0,networks.1.ip=10.99.99.3/24,networks.1.routes=172.16.0.0/16-10.99.99.1
