Description

when executing `route show' on my MP system, I will get varying results.
Additionally, it will print all temporary route entries as well, even for hosts
outside the local network.

Its because its dumping the route table for a particular cpu (whichever
one it happens to be running on). Any fixed routes should always show
the same, but temporary routes are not replicated (if I remember properly)
because this allows the TCP stack, which is cpu-localized based on IP
addresses, to cache routes locally and not bloat the route table for
every cpu.

So, if you see different static routes there's a problem, but if you see
different temporary routes it should be ok.

i think this is still confusing. route show needs to cycle all cpus and merge
the routes.

grab. The plan is:
If -c is not specified, then we merge the per-cpu routing entries.
If -c is supplied, current behaviour will be kept.

Hi Sephe,

Not sure but I believe you've done some work related to this, is that possible?

Cheers,
