redistribution

Hi,

I have following problem:

I redistribute RIP with default route to iBGP. Then other side of network I have to redistribute those routes (including default route) back to RIP. Every route redistributes back to RIP except the default one. Does anyone know how to redistribute default route from iBGP to RIP?

Thanks in advance

Re: redistribution

Antonio,

You shouldn't need any special configuration to redistribute default route from IBGP-->RIP as the other IBGP routes are getting redistributed. The default route on the router you are doing IBGP-->RIP redistribution mightn't be an IBGP route. Perhaps, it's a static default route or route from another source. If you are still having issues, can you share the output of show ip route 0.0.0.0 from the router doing redistribution.

Re: redistribution

Hello Sundar,

Here is the output :

sh ip route 0.0.0.0

Routing entry for 0.0.0.0/0, supernet

Known via "rip", distance 120, metric 2, candidate default path

Redistributing via bgp X, rip

Advertised by bgp X

Last update from 11.0.0.50 on Vlan111, 00:00:12 ago

Routing Descriptor Blocks:

* 11.0.0.50, from 11.0.0.50, 00:00:12 ago, via Vlan111

Route metric is 2, traffic share count is 1

And here is the conf:

router rip

version 2

no auto-summary

redistribute bgp X metric transparent

network 11.0.0.0

router bgp X

redistribute connected

redistribute static

redistribute rip

default-information originate

no auto-summary

no synchronization

On the second router where I redistribute BGP to RIP is simmilar configuration.

Am I doing something wrong in configuration?

thanks

I forgot to send output from the second router (where I redistribute BGP back to RIP)

Re: redistribution

Antonio,

Can you post the configuration of the router redistributing iBGP into RIP.

Re: redistribution

Antonio,

Do you have "bgp redistribute-internal" configured under "router bgp x" on the router where you redistribute from iBGP to RIP?

Re: redistribution

Nevermind my last question. You probably do since the other routes are redistributed back into RIP.

Re: redistribution

Antonio,

I was about to post this information but Harold beat out in posting this info. As Harold stated, you need to configure this command under the BGP process to redistribute IBGP into IGP, RIP in your case.

router bgp xxxx

bgp redistribute-internal

Though, you indicated you see other IBGP routes being redistributed into RIP, I am guessing those all might be static/connected routes rather than IBGP routes since you are redistributing them as well.

Let us know if you have this command configured and are still having issues.

Re: redistribution

Yes I have that command, but default route is still missing in RIP-e

Re: redistribution

I had tried your setup in my lab and the default route was getting redistributed. The only difference in my setup was I had 'redistribute bgp X metric 2' under the RIP process instead of the transparent metric. Configure this and enable 'debug ip rip' and post the output here, if that doesn't help.

Moreover, can you share the full config of the router doing IBGP-->RIP redistribution and 'show ip route summary'.

Re: redistribution

What version of IOS are you running on the router redistributing iBGP into RIP?
