R0106-HP MSR Router Series MPLS Command Reference(V7)

197
sending back a message that includes the Message_ID_ACK object. If the sender does not receive a
Message_ID_ACK within the retransmission interval (Rf), it retransmits the message when Rf expires and
sets the next transmission interval to (1 + delta) × Rf. The sender repeats this process until it receives the
Message_ID_ACK before the retransmission time expires or it has transmitted the message three times.
The initial value of Rf is configured by the rsvp reduction retransmit interval command. The delta value
is configured by the rsvp reduction retransmit increment command.
After the summary refresh is enabled, RSVP maintains the path and reservation states by sending Srefresh
messages rather than standard refresh messages. The Srefresh message sending interval is configured by
the refresh interval command.
