they could do this:
ip route 1.2.0.0 255.255.0.0 Null0
router ospf 1
redistribute static
or configure ospf to only distribute a summary. If they upgrade to an IOS
version dated this decade they can filter announcements with a route-map
(it is of course advisory for you to do the same), they can build a filter
that only allows routes of with a length of /16 to pass through.
Redistributing from a customer into BGP is dangerous. I'd do the following
on your router instead:
ip route 1.2.0.0 255.255.0.0 Serial0
router bgp 1234
redistribute static subnets
Then, the route gets advertised if their leased line is up, and only flaps
if their leased line goes down, and not if their (or your) OSPF process
goes belly-up, or one of the subnets making up the supernet summary flaps.
Take care,
--
