Hi Abhay,
Thanks. Are OSPF control packts just forwarded by P routers on
sham link ? RFC 4577 says that Sham link is treated as OSPF demand
circuit. In case of broad cast or NBMA configured as demand circuit
hello are not supressed as per RFC 1793 section 3.2. that means hello
are also forwarded to the endpoint just as OSPF control packets by P
router on sham link?
Thanks and regards

Only sham link end point needs to be enabled in OSPF and reachable over
the multi hop
network by BGP or static means.
Means Sham Link end points must be routable over the network for it to
become UP.
