Hello Jeff, Folks @ 3000-l,

Re: OT: Routing nightmares

-----------------------------------------------------------Jeff Writes--
PS - Question for James Hofmeister most likely, does the 3K TCP stack
support IGMP?  If so what version?  (Fortunately the 3K isn't involved
yet but you never know).
------------------------------------------------------------------------

I am not sure why this topic was "OT", so I changed the title.  Jeff ask
about IGMP "Internet Group Management Protocol" and support for it on
the HP-e3k.

No, sorry.  Support for IGMP is not available on any release of the
HP-e3k and their is no current lab investigation into this
functionality.

The only network routing protocol that the HP-e3k supports is ICMP
"Internet Control Message Protocol".

Details of the functionality of ICMP and IGMP can be found in "Comer" -
Internetworking with TCP/IP (Third Edition) Volume-I by Douglas E.
Comer.

If IGMP is a requirement, the solution is to place the HP e3k's on a
isolated LAN segment and configure the HP e3k's default gateway to
point to a 2 port router on this segment to reach the primary LAN
segment.  The router will talk to all of the other routers on the
primary LAN segment with IGMP protocol.  The HP e3k will talk to the
local router port with ICMP protocol.

I hope this helps.
