Define RTIMES Association Retransmits

Set the RTIMES parameter such that an association will be marked unavailable after a reasonable amount of time, based on the values of the RMODE, RMIN and RMAX parameters.

For M2PA, this should be just after M2PA T7 expires (default 1.2 sec).

For example, consider a unihomed M2PA link with RMIN set to 100 msec and RMODE is LINEAR:

Time to mark as failed = RMIN * RTIMES 1200 msec = 100 msec * 12

As long as RTIMES = 12, the association will fail at about the same time MTP3 starts changeover procedures (12 is the maximum for RTIMES).

In this case, decrease M2PA T7 slightly using the chg-m2pa-tset command to guarantee that it will expire before the association is taken down.

For M3UA connections, make this a reasonable amount of time for the network, remembering that multihomed associations could be taken down after only RTIMES/2 retransmits.
