Last question We have two provider external VLAN 10 and VLAN 20 I want to add those to provider network to my router then show should i add them and who will be the default gateway, I want to make VLAN 20 default External Gateway.
I have tried following but it only allow single network neutron router-gateway-set ROUTER1 VLAN10 Should i add second VLAN 20 using router-interface-add command?
