Abstract
In some implementations, a network device may receive, from a first other network device, a route that includes a label, a prefix, and a next-hop identifier. The network device may generate, based on receiving the route, a composite tunnel attribute that includes an identifier of the network device and a label allocated by the network device. The network device may modify, based on generating the composite tunnel attribute, the route to cause the composite tunnel attribute to be included in the route. The network device may send, based on modifying the route, the route to a second other network device.
Claims20
A method, comprising:
- receiving, by a network device and from a first other network device, a route that includes a label, a prefix, and a next-hop identifier;
- generating, by the network device and based on receiving the route, a composite tunnel attribute that includes an identifier of the network device and a label allocated by the network device;
- modifying, by the network device and based on generating the composite tunnel attribute, the route to cause the composite tunnel attribute to be included in the route;
- sending, by the network device and based on modifying the route, the route to a second other network device;
- and
- modifying, by the network device, traffic, that includes the allocated label, to cause:
- the allocated label to be removed from the traffic, and
- another label included in another composite tunnel attribute to be included in the traffic.
A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:
- one or more instructions that, when executed by one or more processors of a network device, cause the network device to:
- receive a route that includes a label, a prefix, and a next-hop identifier;
- modify, based on receiving the route, the route to cause a composite tunnel attribute to be included in the route,
- wherein the composite tunnel attribute includes an identifier of the network device and a label allocated by the network device;
- send, based on modifying the route, the route to another network device;
- and
- modify traffic, that includes the allocated label, to cause:
- the allocated label to be removed from the traffic, and
- another label included in another composite tunnel attribute to be included in the traffic.
A network device, comprising:
- one or more memories;
- and
- one or more processors to:
- receive, from a first other network device, a route that includes a label, a prefix, and a next-hop identifier;
- modify the route to cause a composite tunnel attribute comprising a label allocated by the network device to be included in the route;
- send, based on modifying the route, the route to another network device;
- and
- modify traffic, that includes the allocated label, to cause:
- the allocated label to be removed from the traffic, and
- another label included in another composite tunnel attribute to be included in the traffic.
