IPv6 Support for vRouter Loopback Addresses
Netvisor ONE supports IPv4 and IPv6 addresses on the same loopback interface.
When you configure a loopback interface, you can optionally associate a vRouter interface to the configuration. If you do not associate a vRouter interface, Netvisor ONE selects the first non-VRRP vRouter interface. Netvisor ONE uses the loopback interface for a vRouter as a host route in the Forwarding Information Database (FIB) for packets received from any port and routes them to the correct vRouter.
If no configured vRouter interface exists, Netvisor ONE determines the loopback interface unreachable on the network. When you add the first vRouter interface, Netvisor ONE determines the loopback interface reachable.
If you remove the associated vRouter interface, Netvisor ONE selects the next available vRouter interface.
Netvisor ONE does not support multiple vRouter loopback interfaces for IPv6 addresses.
To add an IPv4 address to a loopback interface for vRouter, vr1, use the following syntax:
CLI network-admin@Leaf1 > vrouter-loopback-interface-add vrouter-name vr1 ip 99.1.1.1
To add an IPv6 vRouter loopback interface to vRouter, vr1, use the following syntax:
CLI network-admin@Leaf1 > vrouter-loopback-interface-add vrouter-name vr1 ip 2999:1000::1
To display the vRouter loopback interface, use the vrouter-loopback-interface-show command:
CLI network-admin@Leaf1 > vrouter-loopback-interface-show
vrouter-name     index ip router-if
