摘要:
A given router in the core of a label-switching network identifies a group of routers to receive common label binding information for later routing packets along respective paths through the label-switching network. One way to identify which of multiple routers to include as a member of the group to receive the same label information is to analyze egress policies associated with downstream routers in the label-switching network. Based on this analysis, the given router identifies group members as routers having a substantially same egress policy as each other. The given router then allocates memory resources to store a common set of label information to be distributed to each member in the group of routers having the same egress policy. After populating the memory resources with label information, the given router distributes a common set of label information to each router in the group of routers.
