Failover how much complexity will it add?

I've taken your advice and decided to reconsider my requirement for a full routing table.  I believe I'm being greedy and a partial table will be sufficient.  With regards to Linux/BSD, its not the CLI of quagga that will be an issue, rather the sysadmin and lack of supporting infrastructure for Linux boxes within the organisation.  So things like package management, syslog servers, monitoring, understanding of security issues etc.  I don't want to leave them with a linux/bsd solution that they won't be able to maintain/manage effectively when I am gone.

Thanks for your comments.  Look forward to hearing which solutions come back into the mix having dropped the full routing table requirement.
