redistributing localy injected routes [20060510]

Hi Group,

I have 3 questions regarding redistribution.

Q1.

2 steps:
1. Make an interface part of an IGP via the network statement
2. Redistribute that IGP into another IGP via another link.

In some occasions this will work. For example RIP -> OSPF. Because rip
sees the routes part of the network statement as redistributed from
connected.

I have seen it working for OSPF -> EIGRP as well.

Why doesn't it work for others? Ie. what rule prohibits this.

Q2.

Why doesn't a redistribute RIP to OSPF to EIGRP on the same router work?

Q3.

This merely sums up the questions above I guess. When redistributing, does
the redistribution process go from database to database directly or via
the general routing table? For example does a OSPF proces redistributes
EIGRP routes from the EIGRP topology or from the EIGRP routes in
the routing table?

thanks,

Koen
