Abstract: A method for discovering context using a dataplane programmability protocol. The method includes establishing communication with a network device via a dataplane programmability protocol, sending a context monitoring request, via the dataplane programmability protocol, to cause the network device to perform context monitoring, and in response to the context monitoring request, receiving a context update, via the dataplane programmability protocol, from the network device.

Abstract: According to some embodiments, an Ethernet Virtual Private Network (EVPN) includes a first router configured as an Internet Group Management Protocol (IGMP) version 3 querier and a second router configured as an IGMP version 2 querier. The second router is configured to receive a Selective Multicast Ethernet (SMET) route message generated by the first router. The SMET route message includes an IGMP version 3 join request from a receiver, and the IGMP version 3 join request includes an address of a multicast source device. The second router is further configured to convert the IGMP version 3 join request of the SMET route message to an IGMP version 2 join request. The second router is further configured to send multicast traffic from the multicast source device to the receiver via the first router.

Abstract: In an example method, an instruction to begin monitoring incoming traffic of a multicast data flow is received by a router. The instruction is received from a downstream router. The example method further includes monitoring incoming traffic of the multicast data flow. At least partly in response to determining that an expected amount of the incoming traffic of the multicast data flow is being received at the router, reporting to a network administrator device, a location of the router in the multicast data flow. Further, at least partly in response to determining that an expected amount of the incoming traffic of the multicast a data flow is not being received, sending, by the router and to an upstream router, an instruction to begin monitoring incoming traffic of the multicast data flow.

Abstract: A communication pathway between a plurality of network nodes within a network is established. A DIS election operation is executed to determine a first network node among the plurality of network nodes as the DIS for the network and creating a first pseudo node for the first network node, and with each network node of the plurality of network nodes, determining whether the connectivity between the first network node and the other network nodes of the plurality of network nodes within the network is in a synchronous state with the adjacencies with the other network nodes of the plurality of network nodes within the network.
