rtpSessionInverseTable

table
.1.3.6.1.2.1.87.1.2 · 1 row entry · 1 columns
Open in standard view 
Maps rtpSessionDomain, rtpSessionRemAddr, and rtpSessionLocAddr
TAddress pairs to one or more rtpSessionIndex values, each
describing a row in the rtpSessionTable.  This makes it possible
to retrieve the row(s) in the rtpSessionTable corresponding to a
given session without having to walk the entire (potentially
large) table.
rtpSessionInverseEntry entry .1.3.6.1.2.1.87.1.2.1
Each entry corresponds to exactly one entry in the
rtpSessionTable - the entry containing the tuple,
rtpSessionDomain, rtpSessionRemAddr, rtpSessionLocAddr
and rtpSessionIndex.

created.

can be returned from a tree walk.  When rtpSessionIndex is

rtpSenderSSRC values may be returned.
