摘要

Systems and methods for supporting multiple LIDs for dual-port virtual routers in a high performance computing environment. In accordance with an embodiment, a dual port router abstraction can provide a simple way for enabling subnet-to-subnet router functionality to be defined based on a switch hardware implementation. A virtual dual-port router can logically be connected outside a corresponding switch port. This virtual dual-port router can provide an InfiniBand specification compliant view to a standard management entity, such as a Subnet Manager. In order to allow for packets addressed outside of a local subnet and for those packets addressed to a switch port configured as a router port within a local subnet, the subnet manager can configure the switch port configured as a router port with two or more local identifiers.
