Hello everyone,
I'm exploring OpenWrt since a while and I've that the system has two different implementations of IP aliases.
The first one is documented here and it creates a new interface for each alias.
Example:
config interface 'lan'
option device 'br-lan'
option proto 'static'
option ipaddr '192.168.100.238'
option netmask '255.255.255.0'
option gateway '192.168.100.1'
config interface 'alias1'
option proto 'static'
option device 'br-lan'
option ipaddr '192.168.100.235'
option netmask '255.255.255.0'
The second one is not documented (at least I didn't find any wiki page about it) and it's something like this:
config interface 'lan'
option device 'br-lan'
option proto 'static'
option gateway '192.168.100.1'
list ipaddr '192.168.100.238/24'
list ipaddr '192.168.100.235/24'
Please note that ipaddr
has changed type from option
to list
.
My question is: what is the correct way to setup an alias?
What are the pro and cons of each implementation?
Thank you in advance!
