Marc,
I will ask what kind of Sup720 (3B, 3BXL)you are running??? From your
description, you seem to be running Layer 3 to the access which means
that you will have the OSPF Load balancing across the Uplinks which
means you have 20Gbps Uplinks; If not I would recommend considering
that, Secondly you watch the interfaces utilization and Processor
(which I will believe is still moderate). If you require more
Bandwidth on the Uplinks, Consider Etherchannel (With the hope you
still have free 10GE Ports or slot to insert another module). You may
as well add more DFCs on the Cards to Increase the performance and
take advantage of the distributed architecture of Sup720. Having VSS
will eliminate complexities like Spanning tree blocked ports and HRSP,
but will require you to change your Supervisor engines...
