Hello Darek,
I didn't cacth it. Where is the redistribution in your configs?
Where is the other eigrp process? Please clarify me.
If you do NOT avoid to using 'auto-summary' in your eigrp domain,
summarization will be proceeded only for external networks which
received by this router. Otherwise, you need to switch off
summarization and do it on some interfaces with 'ip summary-address
eigrp...'. It is more preferable method of using EIGRP as IGP in your
network, because BGP does not allow summarizated routes being
redistributed to it without explicit 'network ...' parameter.
DK> Hi,
DK> I'm playing with EIGRP redistribution between two domains and with
DK> address summarization.
DK> I have two concerns.
DK> 1. Doyle on page 726 says:
DK> ... You might expect this route to be suppressed by the summary address
DK> of 192.168.0.0/16. However,
DK> 192.168.4.0/24 is internal to EIGRP 2 process domain; the summarization
DK> applies only to routes being redistributed into the process domain...
DK> I'm trying to reproduce this behavior but it doesn't work this way for
DK> me! When I create summary within domain the more specific routes get
DK> suppressed.
DK> I use IOS 12.0.16
DK> Any ideas?
DK> 2. Admin Distance table specifies AD of summary EIGRP route = 5
DK> How can I observe it in routing table ??? All summary routes show AD=90
DK> beyond the point where they got summarized and like:
DK> 10.10.248.0/21 is a summary, 00:21:22, Null on the router which
DK> summarizes
