[c-nsp] iBGP not propogating route to 0/8

[Justin Shore]

I just noticed that my RTBH setup is not propagating one of my BOGON 
routes.  Specifically it's not propagating 0.0.0.0/255.0.0.0 (0/8).  The 
static is set up just like all my other RTBH routes complete with the 
appropriate tag:

ip route 0.0.0.0 255.0.0.0 Null0 tag 66 name BOGON
ip route 1.0.0.0 255.0.0.0 Null0 tag 66 name BOGON
etc...

A quick check of my advertised routes on my trigger router shows that 
I'm not advertising the prefix.

    Network          Next Hop            Metric LocPrf Weight Path
*> 1.0.0.0          0.0.0.0                  0    500  32768 i
*> 2.0.0.0          0.0.0.0                  0    500  32768 i


The trigger router is in a full mesh with the border routers and core 
routers.  The trigger also peers with each access edge router (which 
also have 2 iBGP peers with their local core routers).

The route-map simply matches each static by it's tag, sets the origin, 
local-pref and assigns a community.

route-map static-to-bgp permit 10
  description Tag 66 sends traffic to Null0
  match tag 66
  set local-preference 500
  set origin igp
  set community 65001:66 no-export

...plus a couple more for other tags.

I can't think of any reason why this prefix wouldn't be advertised.  Any 
ideas?  I noticed it today because I have customers trying to hit 0/8 
IPs (0.4.24.200 for example) that my egress ACLs are catching.

Thanks
