LNS/LAC profile

Hello there

I want to use LNS. but the operator wants us to connect with 4 ip on the LAC side. for example

10.1.1.1.1 password 1111
10.1.1.1.2 password 1111
10.1.1.1.3 password 1111
10.1.1.1.4 password 1111

how can i make this definition. also can i make more than one definition on the LNS side. like based on a profile.

There is an example of LNS/LAC PPPoE over L2TP — VyOS 1.5.x (circinus) documentation
