Abstract

The present invention provides a label processing method, routing information delivery method and device, wherein the label processing method includes: the first edge device receives the label used to identify the routing information advertised by the second edge device; when determining the above label and When the tags assigned by the first edge device conflict, the first edge device compares the first identification information used to identify the first edge device with the second identification information used to identify the second edge device; the first edge device according to The comparison results perform a process of adjusting the label assigned by the first edge device. The present invention solves the problems of cumbersome adjustment of the label pool and high error rate caused by manually configuring the label pool in order to avoid label conflicts in the related art, thereby achieving the adjustment of labels by the edge device without manual intervention , avoiding the effect of cumbersome adjustment of the tag pool and high error rate due to the need to manually configure the tag pool.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a label processing method, a method and device for issuing routing information. Background technique [0002] The Internet technology in the related technologies is becoming more and more mature and the scale is also increasing. Multicast technologies such as interactive network TV IPTV, conference TV, and multicast virtual private network (VPN for short) are used more and more widely. The public network carries multicast streams in various forms, which can well realize the transmission of multicast streams. The user network is connected to the public network, and through the public network, multicast, Multipoint extensions for Label Distribution Protocol (Multipoint extensions for Label Distribution Protocol, referred to as mLDP), Point-to-multipoint Traffic Engineering (Point-to-multipoint Traffic Engineering, referred to as P2MP TE) and other methods can realize the...
