Example:

i own 1.2.0.0/16 and have specific /24 networks behind it.
1.2.3.0/24, 1.2.4.0/24, 1.2.5.0/24.
On my border router, i would advertise 1.2.0.0/16 to my service provider via BGP. I would add a static route:
ip route 1.2.0.0 255.255.0.0 null0

Also to prepare for the future, i would implement BGP at the edge and move to a faster converging IGP (such as OSPF) for the interior of your network.]]> http://www.dslreports.com/forum/Re-Config-Default-route-routing-loop-23307613 Sat, 07 Nov 2009 19:16:53 EDT http://www.dslreports.com/forum/Config-Default-route-routing-loop-23306349 http://www.dslreports.com/forum/Config-Default-route-routing-loop-23306349 Sat, 07 Nov 2009 13:05:40 EDT
