Juniper users,
We've been asked to make a change the clear bgp neighbor command
to make the neighbor or all argument mandatory. The root cause
is the severe impact of clear bgp neighbor and the increasing
accidental use of this command
Hello,
I'm currently looking at an EX4500 setup that had a few problems
related to multicast/broadcast packets going to the CPU (and sometimes
preventing required packets like LACP reaching the CPU) of the switch.
I assume this was because the queue between PFE and CPU was full (is
there a way to
low TTL on the multicast frames will cause this..
Also the multicast destination addresses will do this too if they're in
224.0.0.0/24

Chris, can you elaborate on why low TTL on multicast frames will cause high CPU?
Sebastien, as Chris pointed out anything in the 224.0.0.0/24 will hit the CPU,
but so will a few other ranges that fall into the Link-Local block. This is a
good guide someone else on the list forwarded me a few
Seems like there are several people interested in the responses to this thread.
I’ll check with anyone who responds and post a summary of the information if
allowed by the responders. That being said I haven’t received many responses
at all.
My gut says this is as much a product of Space
I agree. It’s more likely that you had an increase in packets that the switch
would process normally than the switch getting bored and suddenly deciding to
read packets off the wire. If there is an IP interface on the network that the
broadcast/multicast packets traverse, the switch must read

There's no inherent reason
I agree. I could even add a few. A big one is control. I had a supervisor
once who now works for juniper ironically say he didn’t like tools because he
didn’t want to start forgetting the commands. I asked if he was ok with all of
engineering using prod routers as a practice ground. He
