Claim 6:
7. A system comprising:
one or more processors; and
one or more computer-readable media storing computer-executable instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
receiving, at a first router of a first network domain associated with a multi-domain network and from a second router of a second network domain associated with the multi-domain network, a first border gateway protocol (BGP) advertisement packet including a first BGP large community associated with a first next hop node associated with the second router and a second BGP large community associated with a second next hop node associated with the second router;
receiving, at the first router and from a third router of the second network domain, a second BGP advertisement packet including a third BGP large community associated with a third next hop node associated with the third router and a fourth BGP large community associated with a fourth next hop node associated with the third router;
receiving, at the first router and from a first tenant node of the first network domain, a request to send a data packet to a second tenant node of the second network domain;
determining, by the first router and based at least in part on the first BGP advertisement packet and the second BGP advertisement packet, a route for sending the data packet from the first tenant node to the second tenant node; and
sending the data packet from the first router and to one of the second router or the third router based at least in part on the route.
