[c-nsp] OSPF Authentication

[Hudson Delbert J Contr 61 CS/SCBN]

hopefully, your bdr election runs as you expect .... NOT....

no, i think segment by segment is much better as it will segmetize the
election process
as the segments that have the auth configured will not be able to comm with
others...
this can get tricky as i've had to do this very thing before and its not as
easy as rob
seems to think...of course i USED to have comcast cable...the operative
words being 'used to'...

You could go around to all your routers and configure your keys on the
interfaces. There will be no interruption as you are just configuring keys
not enabling the authentication. Then after all the routers have their keys
configured, enable authentication, their will be a small disruption, but
this is why you have maintainence windows :)
