Robert,

The PIC+FPC performs fragmentation when doing IP in IP encapsulation for
packets that exceed the path's MTU. No reassembly is performed by the
Juniper.

The Juniper tunnel PIC is a good solution if you have encapsulated traffic
with high bit rates and/or lots of tunnels.

Regards,
Mike

I'm not positive. I think not, though.

Although that is done at the FPC level and not the PIC level so it is
possible that it is done. If you are a customer you can send the question
to support@juniper.net and get the real answer.
