how does vrrp protocol work?

The Virtual Router Redundancy Protocol (VRRP) is a computer networking protocol that provides for automatic assignment of available Internet Protocol (IP) routers to participating hosts. This increases the availability and reliability of routing paths via automatic default gateway selections on an IP subnetwork.

The GVRP is an IEEE 802.1Q-compliant method for facilitating automatic (dynamic) VLAN membership configuration. GVRP-enabled switches can exchange VLAN configuration information with other GVRP-enabled switches. Policy rules or other network management methods can determine who is admitted to a VLAN.

GigE Vision Control Protocol (GVCP) packets are always received by Wireshark because they are passed through the eBUS Universal Pro driver from the NIC manufacturer's driver, and up to the network stack. ... However, the performance improvements gained by using the eBUS Universal Pro driver are removed by doing so.

Ivrs/Account id/(RAPDRP) is Customer Id works for RADDRP that is for urban area only. This is a 10 digit number as shown in above figure.

In control plane terms, HSRP with vPC is active/passive. This is because only the primary switch responds to ARP requests. ... In a non-vPC deployment, the active HSRP router will have a G flag (Gateway) listed. When a vPC enabled Nexus uses HSRP, both sides get the G flag, allowing both sides to forward traffic.

No matter we connect the cameras to the computer or NVR, we should use the UDP protocol, rather than using TCP/IP. Unfortunately, based on my experience, most video management software/clients and NVRs use the TCP/IP to communicate with network cameras by default.

By nature of the Rapid-PVST protocol being based on RSTP, this also means that Arista switches are backward-compatible with Cisco switches utilizing their proprietary Per-VLAN Spanning Tree Plus (PVST+) protocol.

Virtual Routing and Forwarding (VRF) is a key component of Layer 3 MPLS VPNs. It enables PE routers to appear to be many routers to the customer edge (CE) routers. ... This unique separation of routing tables allows PE routers to store routes and forward packets even if the customers are using identical addressing.

The implementation of vxlan for the linux bridges works encapsulating traffic in multicast UDP messages that are distributed using IGMP. In order to enable that the TCP/IP traffic is encapsulated through these interfaces, we will create a bridge and will attach the vxlan interface to that bridge.

AVRCP (Audio/Video Remote Control Profile) - definition. AVRC is a Bluetooth profile that allows remote control of media playback on other devices. Supported functions are play, pause, stop, next, and previous.

The primary difference between HSRP versus VRRP would be that HSRP is proprietary to Cisco and can only be used on Cisco devices. VRRP is a standards based protocol and is vendor independent allow some flexibility when choosing network devices.

First Hop Redundancy Protocol (FHRP) IP routing redundancy is designed to allow for transparent fail-over at the first-hop IP router. Both HSRP and VRRP enable two or more devices to work together in a group, sharing a single IP address, the virtual IP address.

MSDP uses TCP as its transport protocol. Each multicast tree needs to have its own RP. All of the RPs are peers (directly or through other MSDP peers).

The basic difference between ARP and RARP is that ARP when provided with the logical address of the receiver it obtains the physical address of the receiver whereas in RARP when provided with the physical address of the host, it obtains the logical address of the host from the server.
