Like these:
205.229.60.30 205.229.48.10 255.255.255.255 UGH 0 0 10 eth0
205.229.60.1 205.229.48.10 255.255.255.255 UGH 0 0 9 eth0

The aggregator code in ComOS is Drain Bamaged. This pool should be
advertised as 205.229.60.0/27. Perhaps the PM needs some Cisco features
like being able to nail a route to null0, and then use redistribute
commands and route-maps to tell the router what you want to export into
OSPF.
With just one PM, this isn't a big deal. If I had a stack of PM's
instead of 160 ports in 3 linux boxes running gated, I'd probably be a bit
more concerned about the routing table bloat.
