Hi, The establishment of a wireless Layer 2 link precedes data packets. When a host roams to a new AP to establish a wireless link, the AC responds to the new AP request by sending the binding entries currently in effect from the previous AP to the new AP.
If the binding migration fails, it triggers the host to come back online, thus re-establishing the binding entries. We will add the description in the new version. -- Lin He > -----Original Messages----- > From: Sunanzhi <sunan...@h3c.com> > Sent Time: 2023-06-08 18:40:25 (Thursday) > To: "int-area@ietf.org" <int-area@ietf.org> > Cc: > Subject: Re: [Int-area] New Version Notification for draft-bi-intarea-savi-wlan-00.txt > > > How to consider the timeliness of binding table item migration caused by roaming?
