Abstract
Techniques described herein relate to a method for generating a table for forwarding traffic between networks that are implemented using different types of control planes. In one or more embodiments, the method comprises: receiving a first route advertisement for a first network; extracting a first next hop identifier-multiprotocol label switching (MPLS) label combination; receiving another route advertisement for the first network; and in response to determining that a local label has not been assigned to the first next hop identifier-MPLS label combination: generating a first entry and adding the first entry to a forwarding table of the gateway device.
