Hello all:
I know there have been plenty of off topics running round. I have a pretty
on topic question/confusion about redistribution. I have a very good
fundamental understanding of protocols. I would also argue that I do
understand basic redistribution and can perform it with ease. It is in some
of the more complex environments with mutual redistribution and
multiple redistribution into 3 igps. That really throws me. I have been
working in a self built GNS3 lab that has enough IGP touch points to throw
some nasty routing loops in the network.
http://cisco-voyage.blogspot.com/
Why don't we work on staying on topic and share thoughts about this. Look
at the diagram. What would be required to have stalbe/full/reachbility to
all interfaces in my little network if required to mutually redistribute
all IGPs on R1 (EIGRP,RIP,OSPF), R2 (RIP,OSPF), R3 (OSPF,EIGRP) and also
redistribute connected? Can you come up with appropriate filtering?
Also, instead of just stating ' you can tag in R1' etc. lets see
configurations. I have this running in GNS3. Could open a webex all weekend
and we can do what this group is intended for... CCIE Lab study :)
Regards,
Marc

So I have been starting to redistribute and now seeing this on R1:
