Re: [M3UA] Receving ASP ACTIVE in DOWN State

Yes. So returning Down Ack will ensure the state correction in such cases
also.

Hi Santhana


What do you mean by correcting the peer's state if it is wrong? Are you
trying to say that ASP is in some different state than its state on its
associated SG.

Thanks

Hi Brian/Amir
	Thanks for your opinion and quoting from RFC.
	
	But sending a DOWN ACK in this case would correct the peer's
state also in case if it is wrong. And the message also fits this
scenario. 

4.3.4.2  In ASP DOWN procedures: 5th para "If the ASP receives an ASP
Down Ack message without having sent an ASP Down message, the ASP should
now consider itself to be in the ASP-DOWN state."

	So if a DOWN Ack is sent back then the state can be corrected in
the peer. In spite of it, if we send an ERROR message the peer may just
log the error message. May not take a defined action based on this
error. The Layer Management has to sense the error and correct the state
somehow.

	By this I felt sending DOWN ACK would be better. 

	Please comment. 

Regards
Santhanakrishnan
