Erick,
While BGP conditional advertisement is implemented with the
'advertise-map' and 'non-exist-map' options of the 'neighbor' command, I
was referring to using 'advertise-map' with the 'aggregate-address'
command. So aren't we talking about different things?
I only referred to the 'neighbor' command with the 'unsuppress-map'
option as a means to selectively undo what had been done with an
'aggregate-address suppress-map' command, for a specific neighbor.
But I may have parroted bogus information anyway. After revisiting it,
'advertise-map' with the 'aggregate-address' command allows you to set
the conditions to advertise the aggregate.
Thanks for keeping me on my toes...
Regards,
Mas

Mas Kato,
Correction. The advertise-map has nothing to do with
AS-SET or summarization. It is conditional
advertisement. It uses 2 route-maps (advertise and
non-exist) and if a route goes away then it will
announce another route.
