snat - centralized-Controller |
vlan, vxlan, gre provider |
Full |
Using controller gre needs ovs patch limited to TCP and UDP. NAPT switches are selected from the switches having the port in the router subnet. Failover happens when there is no port in the swtich on the router subnet or when the switch is down. |
||
snat - centralized- Conntrack |
vlan, vxlan, gre provider |
Full |
Used OVS conntrack feature. Works with TCP UDP and ICMP. The NAPT switch selection is based on weighted round robin and a pseudo port of each router subnet is added to the switch. Failover happens only if switch is down. |
