[Ndn-interest] Same LSDB in entire network?

[Lan Wang (lanwang)]

Tanusree,

Every node in NLSR maintains an LSDB (i.e. the topology of the entire network) since NLSR is a link-state routing protocol.  If the network has converged, all the LSDBs should be the same.  Every LSA is signed by its originator and can be verified using a trust model to make sure that the LSA is indeed originated by that origin router.  This is a security benefit provided by NDN’s data-centric security model.  Is this what you mean by “this synchronization of same LSDB in the entire network helps in security"?

Hi all,
One thing I could not be sure about that whether all the nodes in the network have the common LSDB? If so, all the nodes have the idea of topology of the entire network? If NLSR is concerned, so this synchronization of same LSDB in the entire network helps in security also?
