Wouldn't it make more sense to filter in bound default?  or use a single
static default if you where worried about that?

Protection against learning a bad default route through whatever routing
protocol they are learning, since these two routes would be more specific
than any typical default route.  They probably got burned learning a default

Hi,

I have seen a few operators adding static routes like:
0.0.0.0/1 some next-hop and
128.0.0.0/1 some next-hop.

Why would anyone want to add such static routes? What does 0.0.0.0/1
mean. Note that the netmask is 1 and not 0.

Thanks,
Glen
