Looking for a snippet of technical advice...

I'm involved in a project looking at how we might set up a large
SMDS-based IP network.  One of the issues is whether we run multiple
Logical IP Subnets (LISs) or one large LIS.  Before you say anything I'm
not looking for advice on that at the moment! RFC 1209 recommends that
IP-over-SMDS equipment should allow multiple LISs on the same SMDS
interface using different E.164 group addresses (thus allowing a router
between LISs to use a single i/f).  Some of my colleagues who met Cisco
people recently say that the Cisco folk said that's what Cisco does. 

Unfortunately there's no trace of this in the manual: I have the 9.1
Router Products Configuration and Reference and have also looked at the
Errata and 9.1(1) and 9.1(2) release notes but none shows any method of
setting multiple group addresses.  Is this an undocumented feature or is
it planned for a future release? If the latter then which and when?

For what it's worth the command to set the group address is

   smds multicast ip <smds-group-addr>

I'd have expected

   smds multicast ip <smds-group-addr> [<ip-net> <mask>]
