Support for Local Loopback IP Addresses
Netvisor ONE uses the loopback interface as an always up and available virtual interface, and you can assign it a unique IPv4 or IPv6 address. Netvisor ONE uses a loopback interface as a termination address for some routing protocols, because of the availability of the interface. Netvisor ONE 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 ONE deploys the loopback IP address as persistent in the configuration and not affected by a reboot or reset of Netvisor ONE.
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, 12.1.1.1, and the IPv6 address, 1212::1, use the following syntax:
CLI (network-admin@switch1) > switch-setup-modify loopback-ip 12.1.1.1 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
------------ ----------- ----------- ------------
150.1.1.1/24 2001::1/96 12.1.1.1 1212::1
150.1.1.2/24 2001::2/96 12.1.1.2 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:~$
