It depends. If networks 1,2,3,&4 are all subnets of a major network then EIGRP will advertise the major network unless you turn some knobs. Chuck recently pointed out that from IOS 12.0 subnets could be advertised with the "network a.b.c.d wildcard mask" line. If network 4 is its own network then it shouldn't be an issue.
Here's an added goodie. Quoted from the Cisco Press book "EIGRP Network Design Solutions" "The passive-interface default command is implemented in IOS 12.0 and gives you a nice way of configuring routing processes that are supposed to run over a small number of interfaces. In previous IOS versions, you had to configure all the other interfaces as passive." > -----Original Message----- > From: Cisco Nuts [mailto:[EMAIL PROTECTED]] > Sent: Thursday, January 30, 2003 12:01 PM > To: [EMAIL PROTECTED] > Subject: OSPF to Eigrp redistribution??
