There was lot of fuzz about dual-homing feature in R4 CN. Today finally we made a plan to implement it. But guess what, it ‘s extremely over rated. What is dual-homing? ……In short we can say that with dual-homing we provide a backup MSCS for 1 or more MGWs. Thats all we need to say.
- This Active/standby (backup) mechanism will not work if there is connectivity loss between MGW & MSCS.
- Also if one of the peer entity’s connectivity with currently active MSCS goes down, it will not be automatically accessible from standby MSCS.
All in all poor Active/Standby or backup mechansim.
