    Default 6th Edition - Page 437 Redistribution of static route

    Hi there,

    could anybody explain how the missing subnet (10.1.3.0) could find the way back in the routing-tables?

    1. The static-entry with permanent-option keeps it alive in the routing-table of R3
    2. ...?

    But how goes this on? There's no redistribution configured for static-routing, only for translation RIP<->EIGRP.
    "...and it's doing that because we deployed our redistribution command." <- this is confusing me.



    Thanks a lot

    I'm sorry for asking again, but I would appreciate to get a response to this.
    Isn't there anybody out who could help me with that?

    Did I miss any part or understand wrongly?

    Thanks in advance

    I don't have the book with me, but the permanent command keeps the static route in the table regardless if the link is up or not.
    So if the 10.1.3.0 was configured as a static with the permanent command, it will always be in the routing table regardless if that route is non-existent.
    let me know if that answered your question.

    I agree.
    But in the books' situation this route is only permanent @R3 router. And as the output from R1 shows, it gets distributed across the routers through EIGRP.

    Maybe I need to start with some more basic questions (just searched in the book, but didn't find the answer):
    --> In general, which networks will a routing protocol consider for sending out? Does the origin makes any difference? (Direct, Static, RIP, EIGRP, ...) Or will it take the complete routing-table as is, regardless of the origin?
    --> As far I understood, a routing protocol will only take the directly connected networks and the entries of its own type and forward them. So I would need a redistribution to get a static network considered by EIGRP?

    Sorry for asking this, but I currently have some trouble with my test-environment to reproduce this...

    Thanks,
    ronny

    Sorry, but it still rankles.
    Could anybody give me a hint to the right direction?

    thanks
