Re: understanding redistribution

If you redistribute protocol X into protocol Y, protocol X's routes can't
go into protocol Z from protocol Y. You need to also redistribute
protocol X directly into protocol Z to get protocol X's routes into
protocol Z. This may not be easy to follow but it's important to
understand.

The reason behind this is that redistribution is done from the RIB
(routing table) and not done directly between routing protocols. If you
redistribute protocol X into protocol Y then Y will get protocol X's
dynamic routes that are in the RIB (show ip route X) and for IPv4, by
default, the connected interfaces that protocol X is enabled on (i.e.
network statement, ip ospf 1 area 0, etc)

So in your case if you didn't redistribute say static into BGP but are
redistributing static into EIGRP, BGP will not get the static routes that
are redistributed into EIGRP when EIGRP is redistributed into BGP.
