This disclosure describes techniques for enabling interoperability between asymmetric and symmetric Integrated Routing and Bridging (IRB) modes. An interfacing component may be configured to receive a first route advertisement from a first edge node in a Layer-2 (L2) fabric. The first route advertisement may correspond to an asymmetric format route, for instance. The interfacing component may be further configured to receive a second route advertisement from a second edge node in a L2/Layer-3 (L3) fabric. The second edge node may be configured for symmetric integrated routing and bridging (IRB). The interfacing component may be configured to re-originate the first route and the second route such that the interfacing component is included as a hop in the resultant routes between the L2 fabric and the L2/L3 fabric.

This disclosure describes techniques for improving convergence of Protocol Independent Multicast assert state information in multicast groups. A method includes forwarding, by a router, a PIM join message originating from a destination host and stores distribution tree information based on the join message. The method further includes participating, by the router, in a Protocol Independent Multicast ('PIM') assert election among a plurality of routers and storing, by the router, PIM assert state information based on an outcome of the PIM assert election. The method further includes acquiring, by the router, routing information base ('RIB') convergence. The method further includes triggering by the router, or causing, by the router, another router to trigger, a PIM assert among the plurality of routers. The method further includes re-converging, by the router, with PIM assert states among the plurality of routers and storing, by the router, converged PIM assert state information.
