Somewhere along the way, I'm assuming that you WANTED this to occur? ;)

If nothing else, we're seeing why tags are pretty cool to use, at least when
they're used entirely! And why redistribution, or unnecessary
redistribution can come up and bite you unexpectedly!

    Under router bgp use:
    
    Bgp redistribute-internal
    
    That may help your cause there! I assume the other routes are
    externally learned!

    As you can see I learning routes from EIGRP, but I do not understand
    what is happening with the redistribution of BGP in EIGRP on R1... I
    can not see the route 30.30.30.0/24 getting in the routing table? I
    cleared the BGP Process, The EIGRP Neighbors, clear the ip routes, etc
    :D
    
    Something wrong with my config?
    
    Thanks
    Victor.
