Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. A networking device comprising:
one or more processors; and
one or more non-transitory computer-readable media storing computer-executable instructions that, when executed by the one or more processors, cause the one or more processors to:
receive a first route advertisement from a first edge node in a Layer-2 (L2) fabric, the first route advertisement indicating a first route extending from a first host in the L2 fabric, wherein the first edge node is configured for asymmetric integrated routing and bridging (IRB);
receive a second route advertisement from a second edge node in a L2/Layer-3 (L3) fabric, the second route advertisement indicating a second route to reach a second host in the L2/L3 fabric, wherein the second edge node is configured for symmetric IRB;
based at least in part on satisfying a tunnel adjacency rule that allows the first edge node to initiate L2 tunnel adjacency with another L2 edge node, re-originate the first route, to result in a first modified route, such that the networking device is included as a hop in the first modified route extending from the first host in the L2 fabric;
re-originate the second route, to result in a second modified route, such that the networking device is included as a hop in the second modified route to reach the second host in the L2/L3 fabric; and
distribute the second modified route into the L2 fabric.
