Hi Satish,

Sorry for the unicast - I wasn't paying attention to what I clicked to
reply.

Is there a reason that you have to match a tag?  If you're trying to set
up something automated, you'll probably need to get more comfortable
with BGP first.  If you just want to be able to have your upstream peer
drop traffic to a single /32 of yours on occasion (DDOS filling your
pipe, for example) you might be better off starting with a static access
list or prefix list to identify the IP you want to advertise.
