I would really try to avoid the situation. On a lan it's not so bad.
You can use the (undocumented?) netmask table.

set netmask a.b.c.d 255.255.255.255.

On a wan its gonna be difficult. One of the problems we encountered was
the relative slowness of RIP (since thats the only thing a portmaster
can speak). So, if you have multiple hops to a central radius server,
you have a problem. For this reason we only give out static IP addresses
on a LAN. If he wants to connect to another POP, he cant use the same
static address. We encourage people to use dynamic IP, static IP doesnt
scale you know :)

How many ways are there to connect? :)
