BGP "default-information originate" command

[parisdooz12]

Hi,

I have a doubt about the use of the "default-information originate" command in BGP.

Imagine I have in a BGP AS. I don't receive default route from outside.

So I configure a static route to go out of my AS (ip route 0.0.0.0 0.0.0.0 10.0.0.1), then I redistribute this route in my BGP process through the "redistribute static" command.

My question in this cas is: do I need the command "default-information originate" to announce the default route to other routers?

router bgp 65400

[...]

redistribute static

default-information originate

!

ip route 0.0.0.0 0.0.0.0 10.0.0.1

Thanks by advance.

Hi,

You are not allowed to redistribute network 0.0.0.0, so redistribute statc will not include the route 0.0.0.0

You need to use

default-information originate

The way you are configured is correct

Hi,

redistributing static does not work.

But

router bgp 65400

network 0.0.0.0

!

ip route 0.0.0.0 0.0.0.0 10.0.0.1

does.
