Access: read-only
Description: The value used to create the Tie-Break Mask for calculating multicast trees.
What is ieee8021EcmpTopSrvEntryTieBreakMask?
This read-only object, 0 to 15, holds the tie-break mask value used when calculating multicast distribution trees for this backbone service, advertised by ISIS-SPB. An admin inspects this to understand which of several possible equal-cost multicast trees this service instance has been assigned to via the tie-break algorithm. Two backbone services showing different tie-break mask values indicates ISIS-SPB deliberately spread their multicast trees across different equal-cost paths for load distribution.
