    Abstract: 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.

    Abstract: Presented herein are techniques for redacting mirrored network packets prior to providing the mirrored packets to an intended recipient application, such as a third-party analysis application. More specifically, a multi-destination packet redaction device obtains mirrored network traffic that comprises one or more mirrored network packets. The multi-destination packet redaction device filters the mirrored network traffic to determine an intended recipient application of the one or more mirrored network packets and applies a redaction process to redact one or more portions of at least one of the one or more mirrored network packets. The redaction process is customized based on one or more attributes of the intended recipient application.

    Abstract: The techniques describe example network systems providing core-facing designated forwarder (DF) election to forward multicast traffic into an EVPN of a core network. For example, a first PE device of a plurality of PE devices participating in an EVPN comprises one or more processors operably coupled to a memory, wherein the one or more processors are configured to: determine that a first multicast traffic flow has started for the first PE device; in response, send a source-active (SA) route to indicate the first multicast traffic flow has started for the first PE device; receive, from a second PE device, a second SA route that indicates that a second multicast traffic flow has started for the second PE device; and perform an election of a core-facing DF from among the first PE device and second PE device, wherein the core-facing DF is configured to forward the multicast traffic into the EVPN.
