| Description | The (conceptual) table listing group ranges and MSDP peers
used when deciding where to send an SA Request message, when
required. If SA Requests are not enabled, this table may be
empty.
In order to choose a peer to whom to send an SA Request for
a given group, G, the subset of entries in this table whose
(msdpRequestsPeerType, msdpRequestsPeer) tuple represents a
peer whose msdpPeerState is established are examined. The
set is further reduced by examining only those entries for
which msdpPeerRequestsGroupAddressType equals the address
type of G. The entries with the highest value of
msdpRequestsGroupPrefix are considered, where the group G
falls within the range described by the combination of
msdpRequestsGroup and msdpRequestsGroupPrefix. (This
sequence is commonly known as a 'longest-match' lookup.)
Finally, if multiple entries remain, the entry with the
lowest value of msdpRequestsPriority is chosen. The SA
Request message is sent to the peer described by this row. |
