[nsp] Virtual Interface Question

[Siva Valliappan]

turn on keepalives  :)
depending on how fast you want the virtual-access interface to be dropped
vs the load on sending keepalives, you can play with keepalive values.
if you set the keepalive interval to 30 seconds (default is 10), it should
drop within 5x30 = 2 min and 30 seconds.  there may be some AAA tricks
you can do as well to ensure that an earlier session is pulled down
when a new session comes in.  but i don't dabble very much in AAA.
