Hi,
IIUC, this can work with tagged vlan used for the internalapi.
The relevant yaml file snippet (nic1 is where the provision and the internalapi are for example):
type: ovs_bridge
name: br-nic1
use_dhcp: false
dns_servers: {get_param: DnsServers}
addresses:
-
ip_netmask:
list_join:
- '/'
- - {get_param: ControlPlaneIp}
- {get_param: ControlPlaneSubnetCidr}
routes:
-
ip_netmask: 169.254.169.254/32
next_hop: {get_param: EC2MetadataIp}
-
default: true
next_hop: {get_param: ControlPlaneDefaultRoute}
members:
-
type: interface
name: nic1
primary: true
-
type: vlan
vlan_id: {get_param: InternalApiNetworkVlanID:}
addresses:
-
ip_netmask: {get_param: InternalApiIpSubnet}
The InternalApiNetworkVlanID (if different than 20, which is the defaut) has to be set respectively.
Best regards,
Sasha Chuzhoy.
