I searched the archives and found no solution or explanation on this problem. All i am trying to do is delete a route (multicast) from the route table on windows xp.
I am able to do it on my home PC (running win 2K) but am unable to delete a route on my office PC (though i have admin privileges for my machine).
I am a novice at networking.
Here’s the route table.
===========================================================================
Interface List
0x1 … MS TCP Loopback interface
0x2 …00 13 72 a1 a9 f7 … Broadcom NetXtreme 57xx Gigabit Controller - Pac
ket Scheduler Miniport
To support IP multicasting, an additional route is defined on the host. The route (added by default) specifies that if a datagram is being sent to a multicast host group, it should be sent to the IP address of the host group through the local interface card, and not forwarded to the default gateway.
This is added by the system to support multicast, so I don’t think you can ever delete it.
Search the MSDN for “224.0.0.0” and you will find information about IPv4 multicast routing.
Good luck,
Thomas F. Divine

Hi all,
I searched the archives and found no solution or explanation on this
problem. All i am trying to do is delete a route (multicast) from the
route table on windows xp.

this problem. All i am trying to do is delete a route (multicast)
from the route table on windows xp.
I am trying to delete this because i have created my own adapter interface and i want that do handle all my multicast traffic. Unfortunately, the METRIC for my interface comes up with 50 and that of the default is 20 and hence all traffic is routed by my NIC multicast interface.
I am unable to chang the metric value either on the default or on my interface.
It’s really frustrating. I know that i am using the ROUTE.EXE with proper parameters but XP just keeps saying “The route specified was not found” all the time.
Have you tried using the IP Helper APIs to manipulate the route table?
(Search IPHLPAPI on MSDN).
Multicast traffic gets some special treatment (it can go to multiple
interfaces, for instance) and you may still not achieve what you are trying
to do even if you get the route metrics balanced I your favor.
If you really want to ‘steal’ all of the multicast traffic from every other
interface in the system and ‘switch’ it to your NIC, you might need to
rethink the approach and consider an IM driver (or Light Weight Filter on
Vista) which deals with the traffic on the interfaces at the MAC layer.
Good Luck,

Thanks Thomas.
Just out of curiosity, why?
