quote of the day... ospf auth...

you have been warned...

NOTE 
OSPF authentication is a good place for tricky CCIE lab questions—ones that can be solved in a few minutes if you know all the intricacies.

of course...  authentication can create havoc with routing protocols... and yes, the configuration for eigrp, ospf and bgp are unique to each routing protocol...

so what's the plan... you hate it so much that you love it... like frame relay, dtp, vtp, or whatever your particular hateful protocol might be...

bring the hate and you will find the love...

the devil's in the details, baby...
