2) 44.24.221.0/24 will not be configured to have an
IPIP gateway as
it is being announced directly on the Internet.
Networks announced via BGP to the Internet without an IPIP gateway
entry won't be reachable from within 44net including the AMPRGW. This
has been explained and discussed several times over here, BGP
announced network must also have an IPIP gateway entry in to be
reachable from Internet AND 44net. This means that you will have to
provide a non-44net IP address as IPIP endpoint.
