[c-nsp] 7600, DFC's and MPLS

[Kristofer Sigurdsson]

Hi,

Now, I'm not very experienced with the 7600 platform, so bear with me. :)

I have two questions regarding the use of MPLS on the Sup720-3BXL.  From
what I can
gather, I can use MPLS on LAN ports using this supervisor.  However, if I
use DFC3 cards
on 67xx modules, bringing the forwarding decision to the line card, can I
still use MPLS?  Can the
line card, equipped with a DFC3, make forwarding decisions based on MPLS?

Also, SIP modules.  Any points on using those as opposed to OSMs for
non-ethernet WAN interfaces?  Better, worse?

Thanks,
Kristofer
