The following sections describe the flow of network traffic in several
common scenarios. *North-south* network traffic travels between an instance
and external network such as the Internet. *East-west* network traffic
travels between instances on the same or different networks. In all scenarios,
the physical network infrastructure handles switching and routing among
provider networks and external networks such as the Internet. Each case
references one or more of the following components:
* Provider network 1 (VLAN)
* VLAN ID 101 (tagged)
* IP address ranges 203.0.113.0/24 and fd00:203:0:113::/64
* Gateway (via physical network infrastructure)
* IP addresses 203.0.113.1 and fd00:203:0:113:0::1
* Provider network 2 (VLAN)
* VLAN ID 102 (tagged)
* IP address range 192.0.2.0/24 and fd00:192:0:2::/64
* Gateway
* IP addresses 192.0.2.1 and fd00:192:0:2::1
* Instance 1
* IP addresses 203.0.113.101 and fd00:203:0:113:0::101
* Instance 2
* IP addresses 192.0.2.101 and fd00:192:0:2:0::101
