Re: SG view of the ASP

Krishna,

I suppose you could try adding ASP Id to the ASP Up message and see
if the SG recognizes the ASP as one.

However, as Ille suggests, perhaps the problem is the SG's traffic
mode (rather than the AS's traffic mode).

If the SG really believes that the ASP is two distinct ASPs, it should
be sending a NOTIFY("Alternate ASP Active") from SGP1.  If it does not,
IMO it is just a bug, so, perhaps the SG does not truly support Active/
Standby mode.
