[c-nsp] BGP v4 multicast

All,

Just a quick question; what's the best syntax for causing an eBGP 
session with v4 multicast AF to originate routes?

We have:

router bgp 65000
   neighbor 192.168.1.1 remote-as 65001
   address-family ipv4
     neighbor 192.168.1.1 activate

   address-family ipv4 multicast
     neighbor 192.168.1.1 activate

The "ipv4" family gets it routes from other iBGP peers, however none of 
them have (or can support) the "v4 multicast" AF; can I do this:

   address-family ipv4 multicast
     neighbor 192.168.1.1 activate
     network 10.2.0.0 netmask 255.255.0.0
     network 10.3.0.0 netmask 255.255.0.0

...and will it originate 10.2.0.0/16 & 10.3.0.0/16 via multicast to the 
eBGP peer? Is this recommended?
