Hi Authors, I have query regarding “The ESADI (End Station Address Distribution Information) Protocol” as per “draft-ietf-trill-esadi-00” According to draft in Section 5.2<http://tools.ietf.org/html/draft-ietf-trill-esadi-00#section-5.2>Forgetting End Station Addresses If RBridge RBn participating in the TRILL ESADI protocol for VLAN-x is no longer appointed forwarder for VLAN-x on any port where it is providing end station service, it ceases to participate in ESADI after sending a final ESADI-LSP nulling out its ESADI-LSP information. Above will remove/flush the learned L2 entries for that ESADI Rbridge for that vlan and also remove the neighbor ESADI instance entry. Q) What does “nulling out” its ESADI-LSP information mean? Does it means removing the macs and sending an empty MAC Reachability TLV or does it mean that the ESADI LSP wont contain any MAC Reachability TLV at all? Q) In case if ESADI rbridge is AF for a vlan-x and the only End Station which was connected earlier, is removed now, then what will be sent in ESADI-LSP to flush L2 entries for that vlan-x, will it be without MAC Reachability TLV? Please bear in mind that the RBridge has not lost AF for that particular vlan, but has no End Station to send in MAC Reachability TLV. Please let me know for an ESADI RBridge how to distinguish between 1> when to remove learned L2 entries and 2> when to remove ESADI instance neighbor on receiving ESADI-LSP? Thanks, Abhinav
