What are the two primary protocols for multicast?
Multicast protocols such as UDP/IP and RTP/IP are used to broadcast data to any number of receiving devices.
What is multicast enabled?
Multicast routing enabled and Multicast Upstream. Enable Multicast Routing option enables the multicast packets pass-through between internal and external networks while device is operating in Router mode. Multicast intercommunication is based on Internet Group Management Protocol (IGMP).
What is Netstack in Nexus?
The netstack process is a TCP/IP driver in particular – it handles the IP traffic forwarded to the supervisor.
What is multicast passthrough?
IP Multicasting occurs when a single data transmission is sent to multiple recipients at the same time. Using this feature, the Router allows IP multicast packets to be forwarded to the appropriate computers.
What are the Multicast routing protocols?
A multicast routing protocol manages group membership and controls the path that multicast data takes over the network. Examples of multicast routing protocols include: Protocol Independent Multicast (PIM), Multicast Open Shortest Path First (MOSPF), and Distance Vector Multicast Routing Protocol (DVMRP).
What type of multicast is used?
The protocol most widely used for this is Protocol Independent Multicast (PIM). It sets up multicast distribution trees such that data packets from senders to a multicast group reach all receivers which have joined the group.
What are Multicast routing protocols?
What is Netstack?
Netstack is a user-space TCP/IP stack written in Go. When you say scheduling what do you exactly mean. Mostly we don’t do any explicit scheduling but rely on the Go runtime, that said we do a few things to reduce scheduler interactions on the packet processing path to reduce latency.
How do I check CPU usage on Nexus?
Check the CPU resources utilization using the following comands in Cisco NX-OS Release. The “show system resources” command displays the high level CPU utilization for the supervisor module. The “show process cpu” command with the sort option lists all of the processes sorted by the highest CPU utilization per process.
What are multicast routing protocols?
What is Multicast routing used for?
Multicast routing is a networking method for efficient distribution of one-to-many traffic. A multicast source, such as a live video conference, sends traffic in one stream to a multicast group. The multicast group contains receivers such as computers, devices, and IP phones.
Which is Cisco NX-OS release for Nexus 7000?
Note Beginning with Cisco NX-OS Release 5.2 (1) for the Nexus 7000 Series devices, you can configure PIMv4 to run over generic routing encapsulation (GRE) tunnels including outgoing interfaces (OIFs).
What is Bidirectional Forwarding Detection in Cisco Nexus 7000?
Bidirectional Forwarding Detection for PIM. Beginning with Cisco NX-OS Release 5.0(2a), Bidirectional Forwarding Detection (BFD) allows the system to rapidly detect failures in a network. See the Cisco Nexus 7000 Series NX-OS Unicast Routing Configuration Guide, Release 5.x for more information about BFD.
How to enable multicast in Cisco NX-OS?
In Cisco NX-OS, multicast is enabled only after you enable the PIM or PIM6 feature on each router and then enable PIM or PIM6 sparse mode on each interface that you want to participate in multicast. You can configure PIM for an IPv4 network and PIM6 for an IPv6 network.
How is PIM used in a multicast router?
PIM, which is used between multicast-capable routers, advertises group membership across a routing domain by constructing multicast distribution trees. PIM builds shared distribution trees on which packets from multiple sources are forwarded, as well as source distribution trees on which packets from a single source are forwarded.
