Abstract
Some embodiments provide a novel method for assigning a unique internet protocol version 6 (IPv6) link-local address to each interface of a software router implementing a plurality of logical interfaces for a corresponding plurality of logical networks. In some embodiments, the method, for each logical interface, determines a logical network identifier for a logical network corresponding to the logical interface and generates the link-local address based on that logical network identifier (e.g., a virtual network identifier (VNI)).
Claims8
A method of assigning internal link-local IPv6 addresses for logical interfaces of different logical networks that share a same link layer address, the method comprising:
- generating a link-local address for a single port of a managed software router using the shared link layer address;
- advertising the generated address to machines connected to the logical interfaces through a logical domain;
- generating link-local IP addresses for the logical interfaces;
- and
- updating a table to include the link-local IP addresses generated for each logical interface.
