I have a problem....we have link to distribution switch...which was working fine...but now it is flapping continously...and ospf is flooding the network.My question is how to stop the ospf flooding?

Hello Nishant,
if you have a multi-area OSPF domain the ABR node can:
a) create one or more summary routes to hide the flapping routes
area x range x.y.z.0 mask m1.m2.m3.m4
b) eventually you could implement a filter between areas at ABR using area filter-list command
inside a single area you cannot filter the ospf LSA updates.
the only thing you can do until the link is not stable again is to passive the flapping link
router ospf 10
passive-interface gx/y
Hope to help
