RIPv2 - Suppress static route being advertised

[mickd08]

Hello,

Per below, I am advertising a route to a loopback interface (1.1.1.1).

The issue I am having is that the default route is also being advertised which I want to suppress.

I do not have default-route-originate configured.

Sep 21 07:22:25.177: RIP: build update entries
*Sep 21 07:22:25.177: 0.0.0.0/0 via 0.0.0.0, metric 1, tag 0 (Can I prevent this line being sent)
*Sep 21 07:22:25.177: 1.1.1.1/32 via 0.0.0.0, metric 1, tag 0
*Sep 21 07:22:54.760: RIP: sending v2 update to 224.0.0.9 via FastEthernet4 (192.168.10.1)

Is there a way I can suppress the default route being sent ?

Hello,

post the full config of your router as well as the output of 'show ip route'...

Per the trailing bug report below, I have discovered that the problem is with the Cisco IOS we are using.

I have confirmed this by issuing the command default-information originate and then negating the command with no default-information originate. Once done I no longer see the default route being advertised.

Is there a way I can ensure that these 2 commands are always written in the startup-config?  I realize that I can modify the startup-config in a text editor and then copy it to the router, but then if a write command is issued to the router, those two commands will disappear from the config.

no default-information originate
no auto-summary

Cisco BUG CSCvd13306

"no default-information originate" doesn't work unless "default-information originate" is added first

Symptom:

Even without "default-information originate" command default route is seen in RIP database.

Conditions:
Issue is seen with c2900-universalk9-mz.SPA.156-2.T1.bin. It is not seen in c2900-universalk9-mz.SPA.155-3.M5.bin

Workaround:
None
