IF there is a one to one correspondence between Entity and Session how will
the entity be initialised. Should'nt each entity be configured initially
with Label range, Label space, Targetted peer address etc, so that this info
will be used for peer discovery and session establishment.The LdpId used in
the PDU is that of the entity which should have been configured.If this is
so then how can the number of sessions(hence entities) be known apriori,
since this is as a result of peer discovery.
 Also, in the Entity Table the Enity Index is given as optional for
implementations, what is the reason for this?


Does it mean that we start of with an Enity configuration intially and for
each new peer discovered and sesssion established the Entity Table is
updated.


Thanks in advance,
Regards,
Vijay

No, the entity and the peer is one-to-one.

Just because it's indexed this way, using the ldpId and
the peers ldp id in the index it doesn't automatically imply
a one to many relationship.

On the contrary, the ldp session table is augmenting the
ldp peer table and it's specifically a one-to-one relationship
between entity and session, e.g. section 3.1 Overview
"A table is used to configure potential LDP
Sessions, where each row in the table initiates an LDP Session.  This
is the mplsLdpEntityTable"
