The transmission of CSNPs on a LAN is done by the "Designated 
IS", so at least one of your two routers can be silent
	
A CSNP includes information on which part of the LSP DB it 
covers.   Thus the reciever will not set SRM bits for LSPs 
that fall outside the scope of a CSNP.

Subject: [Isis-wg] Multiple CSNPs problem

Hello all,
Kindly clarify the following :
In a broadcast circuit consider 2 Intermediate Systems having the same
contents in their respective LSP databases. At every CSNP interval each
needs to transmit CSNP with the set of LSPs in its database. Considering the
number of LSPs in the database, there may be more than one CSNP required to
be transmitted. If the number of LSPs in the database is more then more than
one CSNP is required to be transmitted. In this case first CSNP contains
only a portion of the LSPs in its database. If this CSNP is received by
other Intermediate system, it sets the SRM flags for the LSPs which are not
listed in the CSNP received. Kindly clarify this.
Thanks and regards
Sivakumar A
