Hi Drew,
-----Original Message----- <SNIP> One idea I had was to use the black diamond as a layer2 switch and then use the GSR to do the routing, but that seems kind of round-about.
Why does this seem round-about? Depending on the line cards and IOS revision you are running in that GSR it could be a really good solution. Black Diamonds in general are not a favorite in the network community right now (re PAIX) but turning into a layer2 only device probably will get you the performance/stability that you need at least until you max-out that layer of your network. It seems like your design is very much a vanilla hosting setup, using small blocks of IP's and isolating each server on its own vlan are great practices. You will find it rather easy to migrate to the above setup because of the way you have done things. Again make sure the line cards and IOS that you use can support the # of vlans and ARP entries that you currently support in your BD setup. _Scott
