Hi!

Thanks. It is right.

But Why the AS 20 is the internal ?

Because this was configured first time? HoW can i control the advertisement distance ?

Thanks,

This is because you are redistributing 100 into 20 - when you look at a device configured in the AS 20 - 100 will be external as it is not in the same AS.

Hi!

I know the redistribution rules.

I do not use the redistributed command. The router distributes automatically from 20 - 100.

The question.

Why the AS 20 is default? How can i change the internal/external status (without route policy-map)?

Thanks

I would like to unterstand how the route select the default AS (internal) for aggregate routes if there are many AS. Is the first the default ?

ok - here is the thing, the last time I checked the only protocol that automatically redistributes dynamic routing protocols is IGRP into EIGRP and vice versa.

Hi!

I very thank your answers!

Unfortunetly we do not unterstand each other. May be my english is not properly.

My quetion once again.

Why the AS 20 is internal for aggregate route? I would like the change the summary-aggregate route eigrp type in the advertisements . The type will be internal In the AS 100 and external in the AS 20.

How can i do this ?

Thank once again!

Post your config (remove sensitive information) for the EIGRP/Interface config for review.

Karoly says he is not using the redistribute command. I agree with Andrew that in my experience EIGRP does not redistribute automatically. The best way to resolve this is to be able to see the config.

It might also be helpful to see the output of show ip protocol.

hi!

I remove the one of 10.42.0.0 summary-route from AS 100 because i had to install now.

Actually the show ip protocols

Karoly

Thank you for the output of show ip protocol. It clearly shows that there is redistribution between eigrp 100 and eigrp 20. The next step is that we need to see the config (at a minimum the complete config of both eigrp processes).
