Here is a network scenario. The customer wishes to run OSPF on the network and
the design should meet his requirements...

                                2 Mbps
                              -------------
  Server Farm ---- A 2 Mbps B
                              -------------
                           | | | |
                           | | | |
                           | | | |
                           | | | | (all 2Mbps links)
                           | | | |
                           | | | |
                           | | | |
                           | | | |

                            1 2

Description: A and B are two main sites with dual 2 Mbps links in between. All
branch sites (1,2,3,4 and so on) have reundant 2 Mbps links to both A and B.

Requirement: Sites 1 and 2 (branches) access the server farm at A through the
direct 2 Mbps link. When this link is saturated to 75%, they should shift to
the other 2 Mbps link and forward the traffic to the server farm through B.

Is this somehow possible while running OSPF in the network??? The customer
does not want to run EIGRP or any other properiatary protocol.

Any suggestions???

Rizwan Afzal.
