Abstract
In some examples, a stitching border network device includes a border tunnel endpoint to connect over a first tunnel to a first network device of a first physical domain, and over a second tunnel to a second network device of a second physical domain. A controller assigns a first broadcast group that includes the stitching border network device and the first network device of the first physical domain, and assigns a second broadcast group that includes the stitching border network device and the second network device of the second physical domain.
Claims18
A stitching border network device comprising:
- a border tunnel endpoint to connect over a first tunnel to a first network device of a first physical domain, and over a second tunnel to a second network device of a second physical domain;
- a memory to store conditional information relating to creation of broadcast groups, and
- a controller to:
- receive a control message from the first network device,
- based on matching a parameter in the control message to the conditional information, assign a first broadcast group comprising the stitching border network device and the first network device of the first physical domain, and
- assign a second broadcast group comprising the stitching border network device and the second network device of the second physical domain, wherein the border tunnel endpoint is to:
- receive broadcast traffic over the first tunnel from the first network device in the first broadcast group, and
- forward the broadcast traffic over the second tunnel to the second network device in the second broadcast group.
A non-transitory machine-readable storage medium storing machine-readable instructions that upon execution cause a stitching border network device comprising a border tunnel endpoint to:
- receive a first control message associated with a first tunnel between a first physical domain and the border tunnel endpoint of the stitching border network device;
- apply conditional information based on matching a parameter value in the first control message to assign the first tunnel to a first broadcast group;
- receive a second control message associated with a second tunnel between a second physical domain and the border tunnel endpoint of the stitching border network device;
- apply the conditional information based on matching a parameter value in the second control message to assign the second tunnel to a second broadcast group different from the first broadcast group;
- and
- store, in a memory, tunnel broadcast group assignment information useable by the border tunnel endpoint to forward broadcast traffic between the first tunnel and the second tunnel.
A method comprising:
- storing, by a stitching border network device, conditional information related to creation of broadcast groups;
- receiving, at the stitching border network device, a first value of a parameter associated with a first tunnel between a first physical domain and a border tunnel endpoint of the stitching border network device;
- assigning, by the stitching border network device based on matching the first value of the parameter to the conditional information, the first tunnel to a first broadcast group;
- receiving, at the stitching border network device, a second value of the parameter associated with a second tunnel between a second physical domain and the border tunnel endpoint of the stitching border network device;
- assigning, by the stitching border network device based on matching the second value of the parameter to the conditional information, the second tunnel to a second broadcast group different from the first broadcast group;
- and
- forwarding, by the border tunnel endpoint, broadcast traffic between the first tunnel and the second tunnel based on the assignment of the first tunnel to the first broadcast group and the assignment of the second tunnel to the second broadcast group.
