In this case, the LMA provides the same IP address to iWAG 2 to enable the mobile node to maintain the
same IP address after roaming. The LMA sends a Proxy Binding Revocation Indication (PBRI) message to
iWAG 1 to delete the binding for the mobile node.
This call flow covers the following:
•
Session roaming from iWAG 1 to another iWAG 2
•
PMIP tunnel creation between LMA and iWAG 2
•
Assigning same IP address to the MN after roaming
•
Session termination
