Advertising default route with BGP

If you want to announce the default route which is statically routed then you have to add following commands to the working BGP configuration:

ip route 0.0.0.0 0.0.0.0 192.168.1.1
router bgp 65001
network 0.0.0.0
default-information originate

when you then clear the ip bgp routing softly (so the current connecting will not be broken)

clear ip bgp soft in
clear ip bgp soft out

you should see that the default route is will be advertised:

sh ip bgp summary
sh ip bgp neighbors IP.ADDRESS advertised-routes
