RE: BGP Default-information originate

Don't confuse this command with the "neighbor x.x.x.x default-originate"
command.

This "default-information originate" command per the doc cd
"the default-information originate command requires an explicit
redistribution of the route 0.0.0.0"

With this example...

The following router configuration mode example configures BGP to
redistribute OSPF into BGP:

router bgp 164

 default-information originate

 redistribute ospf 109

then we have the "neighbor x.x.x.x default-information originate" command...

and per the doc cd (and my own using it in prod) "This command does not
require the presence of 0.0.0.0 in the local router".

Get good at using the doc cd for your answers...

Just like a refrigerator full of red bull and grey goose, its "tough to go
all night and not stop" without a willing drunk milf or a fully
Reference-able guide...

 Guys,

 

Need more Help.

 

Questioning about command default-information originate in BGP

I have search all my e-book, bgp book, no good explanation about
default-information originate in bgp configuration.

 

For exmaple if I have command like this :

 

Router bgp 200

default-information originate

 

When I insert this command into my BGP process, it doesn't effect anything.
My neighbor don't receive any default.

 

So I am thingking maybe it's like ospf default-information originate, when
your router doesn't have a default route, it's not gonna advertise a default
route to it's neighbor.

 

So I guess I insert a static default-route but nothing happens either.

 

Could anyone give me explanation when this command take effect

 

Thanks Guys, really appreciate your help

 

 

Regards
