Thanks,
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 suff=
icient. 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 Lin=
ux boxes within the organisation. So things like package management, syslo=
g 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 bac=
k into the mix having dropped the full routing table requirement.
Regards,
Adel
