<br>The 7600 re-badge was perhaps a step up because it at least had a more capable CPU but on both 6500 & 7600 you often needed a secret-decoder-ring to know what to do / not do in order to remain in the silicon forwarding path.<br>

<br>To be honest, I'd keep 'switches' and 'routers' separate devices. Hybrid approaches seem to be full of compromises.<br><br><br>cheers,<br><br>lincoln.<br></div></div>
