The value of tmnxBsxTransitIpPolicySeenIp specifies
whether or not to initiate dynamic transit subscriber creation when
traffic is detected on a parent SAP or Spoke SDP.
When tmnxBsxTransitIpPolicySeenIp and tmnxBsxTransitIpPolicyRadius
are both enabled a RADIUS Access Request message is sent to the RADIUS
server. The RADIUS server must respond with a transit subscriber
create message.
When tmnxBsxTransitIpPolicySeenIp and tmnxBsxTransitIpPolicyAutoCreate
are both enabled a transit subscriber will be dynamically created for
each IP address without a policy server.
The use of Seen IP to learn transit subscribers is mutually exclusive
with the use of DHCP for this purpose.
