Advertise Default Route with BGP

If you are used to using the “Default-Information Originate” command with OSPF or EIGRP to easily advertise a default route, you might be surprised to find that solely applying that command within BGP does not advertise a default route.  You must also use “Redistribute Static” in conjunction with “Default-Information Originate”.  Your BGP config would look something like this:

router bgp 65000
 no synchronization
 bgp log-neighbor-changes
 redistribute static
 neighbor 10.10.10.10 remote-as 65010
 default-information originate
 no auto-summary

Both commands are needed whether you are using eBGP or iBGP
