Abstract
A route processing method, implemented by a first device, includes: receiving a first route sent by a second network device, where the first route includes a first identifier; allocating, based on the first identifier, a second identifier corresponding to the first route; and sending a second route to a third network device based on the first route, where the second route includes the second identifier. The second network device is located in a first network domain, and the third network device is located in a second network domain.

A route processing method implemented by a first network device and comprising:
- receiving, from a second network device in a first network domain, first route comprising a first identifier, wherein the first identifier instructs the first network device to forward a first packet to the second network device;
- allocating, based on the first identifier, a second identifier corresponding to the first route;
- and
- sending, to a third network device in a second network domain and based on the first route, a second route comprising the second identifier,
- wherein the second identifier instructs the third network device to forward the first packet to the first network device.
A first network device comprising:
- a memory configured to store instructions;
- and
- a processor coupled too the memory, and configured to execute the instructions to:
- receive, from a second network device in a first network domain, first route comprising a first identifier, wherein the first identifier instructs the first network device to forward a first packet to the second network device;
- allocate, based on the first identifier, a second identifier corresponding to the first route;
- and
- send, to a third network device in a second network domain and based on the first route, second route comprising the second identifier,
- wherein the second identifier instructs the third network device to forward the first packet to the first network device.
A network system, comprising:
- a second network device in a first network domain using a first packet forwarding type, wherein the second network device is configured to send a first route comprising a first identifier, wherein the first identifier instructs forwarding a first packet to the second network device;
- a first network device configured to:
- receive, from the second network device, the first route;
- allocate, based on the first identifier, a second identifier corresponding to the first route;
- and
- send, based on the first route, a second route comprising the second identifier, wherein the second identifier instructs forwarding the first packet to the first network device;
- and
- a third network device in a second network domain using a second packet forwarding type, wherein the third network device is configured to receive, from the first network device, the second route.
