Issue with floating static route

Question:

 am having issues with my WS-C3560X-48T-L  floating static route - this must be something easy but I am not "seeing" it today... :-)

I have a few hundred prefixes from the 10.0.0.0/12 range in my BGP table and I want to be able to advertise another range (192.168.1.0/27) when any element of the 10.0.0.0/12 aggregate is present in the routing table. Example: If 10.1.1.1/32 is present, then advertise 192.168.1.0/27. My current problem is that the floating static doesn't kick in, even when the locally originated aggregate is present. Looks like the floating static doesn't like following another static route that is pointing to Null0 (which gets dynamically originated by the aggregate). Currently the floating static only kicks in when a prefix is present in the routing table that has zeros in all of the last three octets, i.e. 10.0.0.0/12 , 10.0.0.0/16 , 10.0.0.0/32

Any solutions / ideas to get around this?

ip route 192.168.1.0 255.255.255.224 10.0.0.0

router bgp 65000

aggregate-address 10.0.0.0 255.240.0.0

network 192.168.1.0 mask 255.255.255.224

CE1#sh ip route 10.0.0.0 255.240.0.0

Routing entry for 10.0.0.0/12

  Known via "bgp 65000", distance 200, metric 0, type locally generated

  Routing Descriptor Blocks:

  * directly connected, via Null0

      Route metric is 0, traffic share count is 1

      AS Hops 0

Answer:

Try changing the next hop address for your static route as follow:

ip route 192.168.1.0 255.255.255.224 10.0.0.1

10.0.0.1 should always be resolvable via the aggregate route (10.0.0.0/12), which should always be present WS-C3560X-48T-S Price in the RIB as long as there is a more specific route in the RIB.
