Routing domain identifier assignment in logical network environments

A non-transitory computer-readable storage medium that includes a set of instructions which, in response to execution by a processor of a computer system, cause the processor to implement a method to assign a routing domain identifier in a logical network environment that includes one or more logical distributed routers and one or more logical switches, wherein the method comprises:

• obtaining network topology information specifying how the one or more logical distributed routers are connected with the one or more logical switches;
• selecting, from the one or more logical switches, a particular logical switch for which routing domain identifier assignment is required, wherein the particular logical switch is distributed on multiple hosts in the logical network environment;
• identifying, from the one or more logical distributed routers, a particular logical distributed router that is connected with the particular logical switch based on the network topology information, wherein the particular logical distributed router is distributed on the multiple hosts in the logical network environment;
• assigning the particular logical switch with the routing domain identifier which is associated with a routing domain of the particular logical distributed router, wherein the routing domain identifier uniquely identifies the particular logical distributed router from one or more other logical distributed routers in the routing domain;
• and
• using the routing domain identifier in a communication between a management entity and each host, of the multiple hosts, that supports the particular logical switch and the particular logical distributed router.

A computer system configured to assign a routing domain identifier in a logical network environment that includes one or more logical distributed routers and one or more logical switches, the computer system comprising:

• a processor;
• and
• a non-transitory computer-readable medium having stored thereon instructions that, in response to execution by the processor, cause the processor to:
• obtain network topology information specifying how the one or more logical distributed routers are connected with the one or more logical switches;
• select, from the one or more logical switches, a particular logical switch for which routing domain identifier assignment is required, wherein the particular logical switch is distributed on multiple hosts in the logical network environment;
• identify, from the one or more logical distributed routers, a particular logical distributed router that is connected with the particular logical switch based on the network topology information, wherein the particular logical distributed router is distributed on the multiple hosts in the logical network environment;
• assign the particular logical switch with the routing domain identifier which is associated with a routing domain of the particular logical distributed router, wherein the routing domain identifier uniquely identifies the particular logical distributed router from one or more other logical distributed routers in the routing domain;
• and
• use the routing domain identifier in a communication between a management entity and each host, of the multiple hosts, that supports the particular logical switch and the particular logical distributed router.
