Re: Eigrp

i think you might be off on the eigrp metric:

EIGRP Metric = 256*((K1*Bw) + (K2*Bw)/(256-Load) +
K3*Delay)*(K5/(Reliability + K4)))

So usually K1 and K3 = 1 simplifying it to

EIGRP Metric = 256*(Bw + Delay)

For the solution to your AD issue which has changed your AD due to
summarization, you could use the 'distance' command under eigrp process to
change AD.

With IOS 12.4T, I also beleive you could use a 'distribute-list in' tied to
route map that matches that route and changes AD to 170 and type external.
