fxp multicast forwarding problems
Hi,
Whilst doing some QA work on XORP on my desktop, which has fxp0 and
msk0, fxp0 got totally hosed.
I was running PIM-SM and IGMPv2 router-mode on the box at the time.
I wonder if this is related to the problems with fxp multicast
transmission I saw back in April.
I'm a bit concerned about this as fxp is still a very widespread and
useful network chip.
I am running 7.0-RELEASE-p4/amd64.
sysctls for dev.fxp.0 are set to...

Hi Laine
What you have suggested sounds eminently reasonable. Thanks for your
advice. I'm going to give it a shot and report back.

...dev01 ~]# tshark -i br1 -f "igmp or host 239.11.12.13"
Running as user "root" and group "root". This could be dangerous.

Multicast routing
How do the Multicast routers sniff IGMP/MLD messages from the network?
I checked the XORP, pimd etc. Most of them just open a RAW socket with
protocol set to IPPROTO_IGMP. But using this the router gets the
packets addressed to 224.0.0.1 only.
How does it receive IGMPv2 and IGMPv3 membership reports sent by other hosts?
Thanks,
Sachin
