del-mfc ...

[Nidhi Bhaskar <bhaskar@scf-fs.usc.edu>]

Hi, 

I have a question on deleting the mfc entries in ns... I am using ns2.1b2.

>From what I can tell, the node proc del-mfc just resets all the slots
in the replicator corresponding to a src,grp pair. The
mcast-classifier is still able to find a slot corresponding to this
replicator. Resulting in no cache misses after you have installed
and then deleted an mfc entry.

Is there some way (already present) that allows deleting
this entry completely, such that it will cause a cache-miss upcall
when packets for the source/group pair are received again?

If not, then given that the replicator calls "drop" is there some way
I can get the incoming interface of the packet that caused "drop" to
be called and use that info to call new-group from there ? Is there
any reason why I shouldn't do this?


Thanks,

Nidhi
