The Cisco Enterprise NFVIS supports multiple IP addresses per interface. A Secondary IP feature can be configured on the WAN
interface, as an additional IP to reach the software. Set the external routes for Secondary IP to reach the NFVIS. Routers
configured with secondary addresses can route between the different subnets attached to the same physical interface.
To access secondary IP through ISRv, the WAN physical port is removed from wan-br similar to single IP.
To configure Secondary IP:
Configure Secondary IP
nfvis(config)# system settings wan secondary ip address 220.127.116.11 255.255.255.0
This feature is used to set the source interface for packets with source IP address, generated by NFVIS using the default
Prerequisites for configuring Source Interface
IP must be one of the configured IP addresses in system settings.
The source-interface IP address can be one of the following:
Source-interface configuration must be applied if the WAN IP is static.
For DHCP, Source-interface IP is accepted but cannot be applied. The configuration takes effect once you switch from DHCP
To configure Source Interface:
Configure source-interface ip
nfvis(config)# system settings source-interface 18.104.22.168
The Secondary IP and Source Interface related errors are logged in show log /var/log/nfvis_config.log file.
