Abstract: In example implementations, a method is provided. The method detects, by a processor, an assignment of a master router role for a virtual router redundancy protocol (VRRP), a protocol independent multicast (PIM) designated router (DR) role for a PIM protocol, and a querier router role for an internet group management protocol (IGMP) to different routers in a network. A communication procedure is initiated to identify which routers of the routers are assigned to the master router role, the DR role and the querier router role. The master router role, the DR role and the querier router role are then automatically aligned to a single router of the routers via an ordered communication exchange.

Abstract: Some examples relate to managing multicast scaling. In an example, a network device may receive a message to join an IP multicast group. The network device may determine whether a hardware filter is available on the network device to process the received message. In response to the determination that the hardware filter is not available on the network device to process the received message, a current state of an IP multicast protocol associated with the message may be changed to an error state on the network device, wherein in the error state, further messages to join the IP multicast group that are received by the network device are discarded by the network device.

Abstract: Examples relate to selectively processing network packets. In one example, a computing device may receive, by the networking device, a network packet from a user device operating on the network; determine that the network packet is a search packet, the search packet specifying a particular service associated with a server device; provide a network controller with a query for the particular service; receive, from the network controller, an indication that the particular service is not provided by server devices operating on the network; and determine, based on the receipt of the indication, not to process the search packet.
