Autoconfiguring level 2 visibility between subnets in a shared network?

[Gonzalo HIGUERA DÍAZ]

Hello.

I was wondering the following: given that a shared-network statement
group subnets that share a broadcast domain (or am I wrong here?),
wouldn't it be useful if a lease obtained for a host in one of those
subnets carried would include information about the rest of the
link-local subnets? In this way, a DHCP-enabled host in
192.168.22.0/24 would be able to talk at level 2 to hosts in
192.168.33.0/24 (asuming both subnets were defined in a shared-network
and really had level 2 visibility). Am I foolish for wanting such an
option, is the DHCP protocol or its implementations the limiting
factor, or have I just not been looking well enough?
