dvmrp

Hello,
      Currently I am developing dvmrp on pSOS, i have the 
following doubts,

1. How to enable multicast routing in pSOS kernel.

2. Should I write seperate routing process.

3. Should I just need to update unicast routing table, if so on 
what basis? because dvmrp(mrouted) maintains two tables, 1> 
routing table 2> forwarding table. which one should be used to 
update current unicast routing table and how.

Thanx and Regards,
gamp
