Local Director 416 and IP Multicast

We are experiencing issues where a Local Director 416, running 4.2.3 code is duplicating a multicast stream received on it's private interface out it's public interface.

The LD interfaces are not secured as there is bridged traffic flowing through it.

Sniffs of the ports on the LD show a single order of packets going in, and an identical packet for every original received packet (two packets out for every one in). The duplicate packets have identical timestamps, IDs, etc.

Anyone ever see this and know of a solution?

Thanks!

Re: Local Director 416 and IP Multicast

This is not expected behavior with the LD.

I did see one bug (CSCdw87752) regarding the LD duplicating multicast packets in 4.2.3. The scenario was slightly different. In the bug, the LD was duplicating multicast packets from a Checkpoint Firewall. That bug is fixed in version 4.2.4. I think it is likely that this fix will also fix your issue.

Let me know if that works or not...
