IGMP and well-known addresses (GLOP)
All,
We have a fairly big network consisting of Juniper core routers and HP distribution switches. One of our TV partners distributes the mc groups with IPs in the range 233.0.0.x - 233.0.4.y. As the doc states, ProCurve switches flood all groups with 0.0 as 2. and 3. octet, due to the GLOP addressing (RFC 2770) in 233/8.
See page 57 in http://cdn.procurve.com/training/Manuals/3500-5400-6200-8200-MRG-Jan08-K_13_01.pdf
Anyone aware of this can be overridden in some way?

Re: IGMP and well-known addresses (GLOP)
You might be able to achieve this with static multicast filters (you can set up to 16):

There is a small bug that I'm aware of at the moment with this feature on the K.13.xx software - when you reboot the switch the filter gets corrupted in the configuration.
As a general courtesy, make sure to assign points to any replies you receive.

Hi,
Well - close, but no cigar.. AFAIK the filter option on ProCurve lets you define specific multicast MACs rather than ranges. Thus, I might be able to filter upto 16 addresses.
