Title:
ルート通知方法及び電子機器
Document Type and Number:
Japanese Patent JP7433483
Kind Code:
B2
Abstract:
The present disclosure provides route notifying methods and electronic devices. In this embodiment, respective ASBRs connected with a second AS in a first AS notify network reachability information (carrying a BIER Path Attribute, where the BIER Path Attribute at least includes BFR IDs of respective BFRs in the first AS) corresponding to a same BFR group prefix to the second AS; when receiving the network reachability information notified by the ASBR in the first AS, the ASBR in the second AS continues to notify a BIER route of the same BFR group prefix in the first AS in the second AS (carrying the BFR IDs of respective BFRs in the first AS), such that a device in the second AS receives a plurality of routes of the same prefix of the first AS and selects one of the plurality of routes as an optimal route based on a route optimization method, thereby reducing BIER route calculation complexity and ensuring subsequent packet forwarding.
