Redistribute static command in Cisco's document???

Hi

Could anyone please describe me about redistribute static route in the following document?

“For example, if a static route is redistributed into IGRP on R5, and then IGRP subsequently redistributed into RIP on the same router (R5), the static route is not redistributed into RIP because it never got entered into the IGRP routing table. This is due to the fact that static routes have an AD of 1 and IGRP routes have an AD of 100 and the static route is installed in the routing table. To redistribute the static route into IGRP on R5, you need to use the redistribute static command under the router rip command.”

Cisco – Redistributing Routing Protocols

Document ID: 8606

http://www.cisco.com/warp/public/105/redist.html

I do not understand the last sentence that why does it use command under the router rip instead the router igrp command?

Thanks a lot,

Nitass

You actually need the redistribute static under both IGRP and RIP in this scenario.

What they mean here is that you can't expect that the static route that is redistributed into IGRP will automatically be redistributed from IGRP to RIP.

This is due to the fact that when you use the "redistribute " command under a routing process, only RIB routes owned by protocol x will be redistributed. In the above scenario the static route in the RIB is still owned by the static route process even though it is redistributed in IGRP therefore it can only be redistributed in RIP if you add a "redistribute static" command under the rip process.

Let me know if I answered your question,

I think there is a mistake in this last sentence. I think the correct would be:

"To redistribute the static route into RIP on R5, you need to use the redistribute static command under the router rip command."

I think that, because the problem in the first place is that "the static route is not redistributed into RIP" when IGRP is redistributed into RIP.
