Claim 16:
17. A 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 (IRM);
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;
establishing a segregated tunnel domain that complies with one or more tunnel adjacency rules;
re-originating the first route, to result in a first modified route of the segregated tunnel domain that includes the interfacing component as a hop in the first modified route extending from the first host in the L2 fabric;
re-originating the second route, to result in a second modified route of the segregated tunnel domain that includes the interfacing component as a hop in the second modified route to reach the second host in the L2/L3 fabric;
receiving data traffic from the first edge node via the first modified route; and
forwarding the data traffic to the second edge node via the second modified route.
