will an ASBR between 2 EIGRP AS's auto-redistribute?

If I have a single router with int F0 assigned an ip of 1.1.1.1 and int F1 assigned an IP of 1.1.1.2 with the following EIGRP config...

RouterA:

router eigrp 1

network 1.1.1.1 0.0.0.0

no auto-summary

redistribute static

redistribute connected

router eigrp 2

network 2.2.2.2 0.0.0.0

no auto-summary

redistribute static

redistribute connected

...will EIGRP automatically redistribute between ASs or does this automatically happen.

In either case I would imagine that all routes advertised by RouterA would be advertised with an AD of 170. Is this correct?

Thanks much!

Hi,

No, the redistribution won't be done automatically.

The AD of normal EIGRP is 90 (not the redistributed), and the external route (from redistribution) is 170, and EIGRP summary route is 5.

HTH please do rate all helpful replies,

re AD: Correct, so in this case all routes would be advertised with an AD of 170.

The metrics will be pulled in between the two processes, once you've configured redistribution. You can override this using the default metric command under router eigrp, or using the metric keyword on the redistribution command.

The automatic reditribution that you are talking about is the case when you have routers running IGRP & EIGRP with same AS.

e.g. IGRP 100 & EIGRP 100 will redistribute automaticaly.

Actually, if you manually redistribute between two EIGRP processes, the receiving process will pull the metrics from the sending process. This hasn't always been true, but it is true in current code. IGRP is gone--pulled from the code.
