1. A computer-implemented method comprising:
receiving, at an interfacing component, 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);
receiving, at the interfacing component, 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;
re-originating the first route, by the interfacing component, to result in a first modified route, such that the interfacing component is included as a hop in the first modified route extending from first host in the L2 fabric, wherein the re-originating includes applying a tunnel adjacency rule that defines one or more types of tunnel adjacencies that are permitted to be initiated by the first edge node; and
re-originating the second route, by the interfacing component, to result in a second modified route, such that the interfacing component is included as a hop in the second modified route to reach the second host in the L2/L3 fabric; and
distributing the first modified route into the L2/L3 fabric.
