Does a Teredo client send keepalive packets to Teredo Relays to maintain a mapping in the NAT ...

["John Spence" <jspence@native6.com>]

I apologize if this is in the spec - I could not find it.  I see
the Teredo client sends keepalive packets to the Teredo Server to
maintain it's address.    Does the client send keepalives towards
active Relay's to maintain the mapping for active sessions?  Of
if a sessions through a Relay goes quiet for 2 or 3 minutes is
the session considered ended?

Thanks.
