Support for Local Loopback IP Addresses

NetVisor OS uses the loopback interface as an always up and available virtual interface, and you can assign it a unique IPv4 or IPv6 address. NetVisor OS uses a loopback interface as a termination address for some routing protocols, because of the availability of the interface. NetVisor OS allows you to configure a loopback address for a global zone.

  • Send a dedicated ping to loopback interface
  • Create a BGP neighbor using the loopback Interface with OSPF so reach-ability is there for BGP and BGP next hop self
  • Make sure log messages do not show any issues

NetVisor OS deploys the loopback IP address as persistent in the configuration and not affected by a reboot or reset of NetVisor OS.

To add a loopback IPv4 or IPv6 address or both to an existing configuration, use the following syntax:

CLI (network-admin@switch1) > switch-setup-modify loopback-ip ip-address loopback-ipv6 ipv6-address

For example, to add the IPv4 address,, and the IPv6 address, 1212::1, use the following syntax: 

CLI (network-admin@switch1) > switch-setup-modify loopback-ip loopback-ip6 1212::1


CLI (network-admin@switch1) > switch-setup-show format in-band-ip,in-band-ip6,loopback-ip,loopback-ip6, layout horizontal

in-band-ip   in-band-ip6 loopback-ip loopback-ip6

------------ ----------- ----------- ------------ 2001::1/96    1212::1 2001::2/96    1212::2

After configuring the loopback address, you can SSH to the switch over the management, in-band, or loopback interface using the following syntax:

CLI (network-admin@switch1) > ssh network-admin@<mgmt/inband/loopback ip-address>

Then from CLI, execute the shell command to access the switch shell:

CLI (network-admin@switch1) > network-admin@switch:~$
