Hi,

How can stop the ip summary-address eigrp from generating a
null route. I want the summary address to point to an
interface and not have the detailed being advertised.

I thought that:

ip summary-address eigrp 1 192.168.3.0 255.255.255.128 255

would do it with a distance of 255 but...

Here is the interface:

interface Serial0
 ip address 192.168.3.130 255.255.255.224
 no ip directed-broadcast
 ip summary-address eigrp 1 192.168.3.0 255.255.255.128 255
 service-module 56k clock source internal
end

Here is the EIGRPs

router eigrp 1
 redistribute ospf 10 metric 10000 20000 255 1 1
 redistribute eigrp 2
 passive-interface FastEthernet0
 network 192.168.3.0
 no auto-summary
!
router eigrp 2
 redistribute ospf 10 metric 10000 20000 255 1 1
 redistribute eigrp 1
 network 172.16.0.0
 network 192.168.4.0
 no auto-summary
!

This is from Doyle route redistribution Chapter 11, EIGRP
<==> OSPF

I get the following in the routing table of Robinson, the
one doing the redistribution:

c1720#r 192.168.3.0
Routing entry for 192.168.3.0/24, 7 known subnets
  Attached (2 connections)
  Variably subnetted with 3 masks
  Redistributing via ospf 10, eigrp 1, eigrp 2
