PIM sparse multicast problem in Cisco/HP campus network
Our campus network uses Cisco 6500/SUP720
at the core, and HP Procurve 5400zl for
building routers.
Multicast streams across campus will
drop for 1 second, every minute,
as the Cisco sees a prune from HP,
and then a join 1 second later.
Here are the logs from Cisco:
*Mar 4 00:21:49.849: PIM(0): Received v2 Join/Prune on GigabitEthernet1/0/24 from 10.0.0.2, to us
*Mar 4 00:21:49.849: PIM(0): Join-list: (*, 239.255.100.100), RPT-bit set, WC-bit set, S-bit set
*Mar 4 00:21:49.849: PIM(0): Update GigabitEthernet1/0/24/10.0.0.2 to (*, 239.255.100.100), Forward state, by PIM *G Join
*Mar 4 00:21:49.849: PIM(0): Prune-list:(10.0.3.2/32, 239.255.100.100) RPT-bit set
*Mar 4 00:21:49.849: PIM(0): Prune GigabitEthernet1/0/24/239.255.100.100 from (10.0.3.2/32, 239.255.100.100) - deleted
*Mar 4 00:21:50.848: PIM(0): Received v2 Join/Prune on GigabitEthernet1/0/24 from 10.0.0.2, to us
*Mar 4 00:21:50.848: PIM(0): Join-list: (10.0.3.2/32, 239.255.100.100), S-bit set
*Mar 4 00:21:50.848: PIM(0): Add GigabitEthernet1/0/24/10.0.0.2 to (10.0.3.2, 239.255.100.100), Forward state, by PIM SG Jon
This happens in the production net, and
in a little lab environment with a Cisco 3750
and HP 3500yl, and 2 laptops.
Here are the configs from our lab setup:
http://ist.uwaterloo.ca/~ykolomiy/multicast-lab-configs.txt
(note we've tested it in production with
K.12.43, and it didn't help)
We have a case open with HP.
Any advice on workarounds, or whether you
have seen this before, would be greatly
appreciated.
