what, and there's no authentication available in OSPF then Chuck?
I have been playing with some Foundrys (Foundries maybe?) this week (new
job, new toys ) and one specifies whether an interface is OSPF-enabled
on a per-interface basis - ie as a part of the interface config.
This makes a lot more sense to me than the somewhat indirect way under IOS -
it used to drive me mad when people used to "aggregate" an OSPF network
statement to pull in multiple interfaces - I do a statement per-interface,
whether an aggregate is avialable or not. Interesting however that Cisco
IS-IS does protocol-enabling of the interface as part of the interface
config though - is there some apocrophal (sp?) historic reason for this?
Not really making a point I suppose, just some late-night musings.
