I had a similar problem in 5.0Ap36:
customer has a full "C" network block, max is announcing via OSPF
Destination Gateway IF Flg Pref Met Use Age
10.165.218.0/24 10.165.218.1 wan8 rGT 50 1 62855 12588
10.165.218.0/24 10.165.218.1 wan8 *SG 120 7 23 1320416
10.165.218.1/32 10.165.218.1 wan8 rT 50 1 106 12818
10.165.218.1/32 10.165.218.1 wan8 *S 120 7 3 1320646
In configuring my ciscos for BGP I had a static route
for 10.165.218.0/24 pointing to null0 with a metric of 250.
the same route was configured on all the cisco border routers,
all were redistributing static->OSPF.
after a few days/hours the /24 route would disappear from the max,
and only the /32 would remain, thus blackholing the traffic at the cisco.
disconnecting and reconnecting the link brought the route back.
after removing the static route on my ciscos the problem vanished,
with the downside of flapping the BGP route if their link went down.
havn't tested again with 6.0 beta.
