Hi, does this also apply to IPv6 routing protocols? I remember having
ran into a problem a while ago because as I remember it was not
redistributing connected interfaces running the protocol
automatically... I might be wrong... ;)

Bear in mind that there is no double redistribution on the same router.
For example, let say you have OSPF and RIP running on a router. OSPF is
running on E0/1. RIP is running on E0/0. As part of your OSPF
configuration, you are redistributing connected into OSPF.
However, you are using a route-map to only redistribute your loopback
into OSPF. Here's the diagram:
(OSPF) E0/1----- R1 -----E0/0 (RIP)
|
Lo0
Now, when you redistribute RIP into OSPF, E0/0's network will not show
up in your OSPF domain. OSPF will pick up all of the routes from sh ip
route rip (step one from Brian's explanation). Then, it skips the
second step of bringing in the connected interfaces that RIP is enabled
on, because you are already redistributing connected.
Connected interfaces are only brought into a protocol once.

with IP 1.1.1.1, then 1.1.1.0 will appear as directly connected in the
ROUTING table. When we redistribute OSPF into another routing protocol,
does it include 1.1.1.0 also in the redistribution?
