I received a new allocation from arin, a /22 and today i went to add it to 
my 3750.

I did the following....

router bgp xxxxxx
 network 204.xxx.132.0 mask

ip prefix-list routes_to_upstream seq 10 permit 204.xxx.132.0/22 le 32

when i do a sh ip bgp i dont see the /22.  I though maybe it was because the 
space had not been carved up and assigned to anything yet so i assigned a 
/29 from it to a vlan.  Still doesnt show up.

Any idea whats going on here?
