My recommendation:
1. Connect 6509 by multiple gigabit links. Run GEC + ISL.
2. Use the MSFC on 6509 to route between VLANs.
3. Use MHSRP to load-balance active VLANs on all the MSFCs.
4. Use 4003 for L2 switching. May have multiple VLANs per switch and routed by the
6509.
5. Each 4003 has 2 gigabit uplinks (with ISL) to both 6509. This provides
redundancy. To prevent looping, run spanning tree per vlan.
I have several clients using such a design. Hope this help.
Cheers,
YY

Subject: A design problem of switched network
Now I want to design a lan for a company, i want to use 2 6509s as core
switches for redundancy ,several 4003 as distribution switches .Each 4003
connect to 6509 seperately ,2 6509 connect to a pix which links to
internet.
What puzzled me is how to deal with these 2 6509s.Do they need to be
connected with GEC technology and apply HSRP on them ?If they don't have
links ,which link should a 4003 choose to visit internet?
Thanks,
Frank
