Abstract
A system may include a first border network device located between a first network domain and a third network domain, and a first edge network device in the first network domain, where the first edge network device may be configured to receive a packet. The packet may be directed to a second edge network device in a second network domain. The first edge network device may also be configured to add a second label to the packet that identifies a second border network device located at the border of a second network domain and the third network domain. The third network domain may be located between the first network domain and the second network domain. The first edge network device may additionally be configured to add a first label to the packet that identifies the first border network device, and route the packet to the first border network device.
