Hello all,

 

We need your suggestion on the behavior of M3UA on o= verride mode in IPSP single exchange and IPSP double exchange mode.

 

Query-1<= /u>

 

In the definition of I= PSP double exchange model  (RFC section 4.3) it is mentioned that the = RKs define the traffic to be directed to the peer as in the AS-SG model. Fr= om this we conclude that the traffic to be directed to peer for AS-SG model is analogous to IPSP = ; double exchange.  

 

Is our understanding correct ?

 

/Query-1

 

Query- 2

 

As per the specifications RFC 4666 section : 4.3.4.3= ( page No : 84, 4th Paragraph) the behavior of Override mode f AS to be as= follows:

 

“In the case of an = Override mode AS, receipt of an ASP Active message

at an SGP causes the (re)= direction of all traffic for the AS to the

ASP that sent the ASP Act= ive message . Any previously active ASP in

the AS is now considered = to be in the state ASP-INACTIVE and SHOULD

no longer receive traffic= from the SGP within the AS. The SGP or

IPSP then MUST send a Not= ify message ("Alternate ASP_Active") to the

previously active ASP in = the AS and SHOULD stop traffic to/from that

ASP. The ASP receiving th= is Notify MUST consider itself now in the

ASP-INACTIVE state, if it= is not already aware of this via inter-ASP

communication with the Ov= erriding ASP.”

 

The following behavior= is clear from the specifications when SGP  or IPSP receives ASP activ= e message from an ASP.

 

1.       Previously active ASP SHOULD no longer receive traf= fic from the SGP within the AS

2.       SGP or  IPSP then MUST send a Notify message (= "Alternate ASP_Active") to the previously active ASP in the AS.

3.       SGP or IPSP should stop traffic to/from the previou= sly active ASP.  

  

 

Please share on inputs on following:

 

Is the above text in double quotes from specifica= tions(RFC 4666 section : 4.3.4.3 ( page No : 84, 4th Paragraph)), valid for= (i.e. is override mode support for which of the following configurations)<= o:p>
