The MIB module describes generic Ipsec Endpoint Pair information
of RapidStream system. Mainly, the information
obtained from this MIB is used to constructed topological
view of IPSec security gateways that are connected by
An IPSec Endpoint Pair is a pair of security gateways that
are connected with 0 or more IPSec SA's in tunnel mode.
It contains information of aggregated information
of tunnel mode SA's between two security gateways.
An IPSec Endpoint Pair is identified by a pair of IP addresses.
Therefore, if an IPSec security gateway X has 2 external
IP addresses while IPsec secruity gateway Y has 3 external
IP addresses, there are potentially 6 IPsec Endpoint Pairs
between X and Y.
