<p>The present invention discloses a method for multi-domain inter-domain routing maintenance, which includes: when a node joins, searching an extra-domain routing node corresponding to said newly joined node in the other domains outside the domain where the newly joined node locates, and establishing an inter-domain routing path from the newly joined node to the extra-domain routing node, wherein the extra-domain routing node is the node whose node identifier in the domain where said extra-domain routing node locates complies with the preset inter-domain routing establishment rule with the node identifier of the newly joined node; and the nodes in the other domains establish or adjust the inter-domain routing paths to the domain where the newly joined node locates according to the inter-domain routing establishing rule. The present invention can reduce the inter-domain routing maintenance cost.</p> |
