[c-nsp] Ip unnumbered on 3750

Hi All

I was playing around with an ip unnumbered config for our Dist-layer.

I got a working config on a 3560 ie

int loopback 10
ip address x.x.x.x y.y.y.y

Vlan x
ip unnumbered loopback 10

Vlan x1
ip unnumbered loopback 10

Vlan x2
ip unnumbered loopback 10

The same wont work on 3750 which gives the following when inputing the
"ip unnumbered" command.

Point-to-point (non-multi-access) interfaces only

My question is, is there a work around for this or will 3750 never
support "ip unnumbered" on multi-access interfaces?

Best regards
