Hi Les, *[LES:] Even a modest sized N = 100 (which is certainly not a high number) > leads to 10000 BFD sessions. N= 500 => 250,000 sessions. Etc.* > > Are you doing N^2 ? Why ? All you need to keep in mind is number of those sessions per PE so in worst case (N-1) - here 99 and 499.
And as we already established, configuration is optional as you can use auto config.
