CPU utilization on a software based router is not linear, said in a
different way, even when CPU hits 100% it can still forward
significantly faster.

Not all IOS versions have 802.1q subinterfaces in the ifTable, 12.0S and

Even though Amsterdam (and AMS-IX) is a major hub for european
connections, most worked as usual, though some Dutch destinations has
higher than normal delay and packet loss.

nge, causing a new next-hop interface for
100k routes, will cause processes (probably CEF related) to run for so
long, that you will loose your BGP keepalives, thus loose sessions, and
everything will go *BOOM* - so please be nice and don't do that without
real testing.

So basicly 12.0(22)S is what would have been 12.0(22)ST if they hadn't
renumbered.
The "old" S train will be recieving bug fixes as 12.0(21)S1 S2 S3 etc.
for a limited period of time.
So be carefull when you go from 12.0(x)S, x

's not always { an option | done | ... }.
If A and B exchange say 200 Mbps of traffic, moving to a PNI is for sure
a option, but if both have GigE connections to the shared infrastruture
with spare capacity, both can expect the IX to handle that traffic.

ithm, you will have problems.
A large IX in Europe have this exact problem on their Foundry swiches,
which doesn't support round robin, and is currently forced to moving for
10 GigE due to this very fact.
