rip and Null0 being advertised with metric 16

I am working a lab from the BSCI lab manual...

Trying to summarize some routes with RIP...

lab guide says do this:

ip route 192.168.48.0 255.255.252.0 null0
router rip
redistribute static

However the summarized route is not appearing in the other router, only on the locally configured device.

When I debug the rip protocol I see that the summarized route is being advertised with a metric of 16 so of course it will not make it into the routing table of the other router.

So I tried doing this:

router rip
version 2
redistribute static route-map stat_to_rip
passive-interface Loopback0
passive-interface Loopback48
passive-interface Loopback49
passive-interface Loopback50
passive-interface Loopback51
passive-interface Loopback70
network 172.16.0.0
network 192.168.48.0
network 192.168.49.0
network 192.168.50.0
network 192.168.51.0
network 192.168.70.0
no auto-summary
!

route-map stat_to_rip permit 10
set metric 1

but the metric is still showing up as 16 on the same device...

Does anyone see an error in my config or know of a work around?

Thanks

another interesting tidbit:

Routing entry for 192.168.48.0/22, supernet
Known via "static", distance 1, metric 0 (connected)
Redistributing via rip
Advertised by rip route-map stat_to_rip
Routing Descriptor Blocks:
* directly connected, via Null0
Route metric is 0, traffic share count is 1

and debug out put shows this:

*Mar 1 01:56:49.099: 192.168.48.0/22 via 0.0.0.0, metric 16, tag 0

very odd....

Post the complete config of the router you are working on.
"redistribute static route-map stat_to_rip" Do you not think this is a long winded approach?
You could have just used "redistribute static metric 1" or
router rip
default-metric 1
redistribute static

You do understand the reason behind making the static route to null?

I was working on this for a while and found some other examples suggesting I try this method

I also tried both of these methods:

You could have just used "redistribute static metric 1" or
router rip
default-metric 1
redistribute static

Unfortunately I lost the previous config I was working on, so I need to re-lab it and I will post the new lab tomorrow (or later tonight).

Here is the running config of the problem router....

I have tried (shown below)

router rip
default-metric 1
redistribute static

and (not shown, nothing more than the line below, which the lab states is the correct method)

redistribute static

and (also not shown)

redistribute static metric 1

none of them are working to change the metric of the static route....

Man do you ever sleep?

Do you see anything wrong with my configuration?

I see a few lines that you have that I don't, but I am not certain they are needed to make this work. I will try one more time and see if I can get this to work. The only thing I can think of is that I am using GNS3/dynamips... Perhaps I would be better off if I setup some real routers for this one.

I've got a touch of insomnia

,but going to bed in 1 hr.I pasted your config in complete, any additionals are ios defaults.I used dynamips too.

Well, I just rebuilt my entire config with 7200 ios instead of 3640... And

BINGO!!!!

So it is a bug with the 3640 ios or a bug with that IOS and dynamips.... Go figure....
