i'll see if i can recreate the problem inhouse in my copious free-time ;)
would appreciate it if you can open a TAC case on this issue so that
we don't lose track of it. i believe you can still use RBE,
but use RBE with the un-numbered version. that would work for you:
i.e.
if you want all your users on 10.1.1.1/24 subnet
int loop 0
ip address 10.1.1.1 255.255.255.0
int atm 2/0.1 point
ip unnumbered loop 0
ip helper-address <blah>
! use ip helper if you want to tie DHCP to RBE unnumbered
! this way we will automatically install a host route to each subscriber
! as they come up
atm route-bridged ip
pvc 2/32
.
.
.
ip route 10.1.1.2 255.255.255.255 atm 2/0.1
ip route 10.1.1.3 255.255.255.255 atm 2/0.2
! you only need the host routes if you are not going to tie RBE to DHCP
would this work in your scenario?
thank you
