You obviously don't know what you are talking about! Does Juniper need to be in every space to compete with Cisco? The short answer is no. Do they need to be in the Enterprise Switching space to compete with Cisco, for sure. Anyone that has half a brain isn't going to use a single vendor for an enterprise network unless they really don't know what they are doing (which is the case these days). If your enterprise uses Cisco over Riverstone or Juniper for WAN Opt. or Cisco over Juniper or Nokia for Firewalls or SSL VPN, then you are living under a rock. Bottom line is that a single vendor network is not the best network. So crawl out from under your rock and use Cisco, Juniper, Nortel, Avaya, Extreme, Foundry, F5, Force10, Riverstone where it makes sense. BTW I would take Juniper support over Cisco's any day of the week despite my escalation via CCIE.
