What protocol does HSRP use?
HSRP is an application layer protocol. HSRP version 1 uses UDP port number 1985 and multicast address 224.0. 0.2 and version 2 uses UDP port 1985 and 224.0. 0.102 as multicast address.
What does Eigrp RTP do?
EIGRP uses Reliable Transport Protocol (RTP) to ensure that packets are delivered in order and to ensure that routers receive specific packets. A sequence number is included in each EIGRP packet.
How does VRRP protocol work?
VRRP enables hosts on a LAN to make use of redundant routing platforms on that LAN without requiring more than the static configuration of a single default route on the hosts. The VRRP routing platforms share the IP address corresponding to the default route configured on the hosts.
What is RTP routing?
The Real-time Transport Protocol (RTP) is a network protocol for delivering audio and video over IP networks. RTP typically runs over User Datagram Protocol (UDP). RTP is used in conjunction with the RTP Control Protocol (RTCP).
What is RTP and dual in EIGRP?
“Reliable Transport Protocol (RTP) is responsible for guaranteed, ordered delivery of EIGRP packets to all neighbors. It supports intermixed transmission of multicast or unicast packets. For efficiency, only certain EIGRP packets are transmitted reliably.
What is the use of VRRP?
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.
How do I configure HSRP protocol?
To achieve basic HSRP configuration, you need to do the following:
- Configure normal IP address on interface (cannot be the same as HSRP virtual IP)
- Bring interface up (no shutdown)
- Configure HSRP group and virtual IP address using the standby command.
What is AVG and AVF in Glbp?
GLBP concepts : The Actual Virtual Gateway (AVG) provides virtual Mac addresses to all the other routers operating GLBP of the same group. The remaining routers are Actual Virtual Forwarder (AVF).
What is HSRP v2?
HSRP, HSRP version 2. Hot Standby Routing Protocol (HSRP) is Cisco standard of providing redundancy for IP host configured in a LAN network with default gateway address.It enables a set of router interfaces to work together to present the appearance of a single virtual router or default gateway to the hosts on a LAN.
What is HSRP (HSRP)?
HSRP (Hot Standby Router Protocol) is a Cisco proprietary First Hop Redundancy Protocol (FHRP). HSRP first hop redundancy mechanism provides alternative path as a proactive action for any failure on a device. In this lesson, we will learn the protocol and in the following lessons, we will also learn HSRP Configuration.
What is the UDP port number for HSRP?
HSRP is an application layer protocol. HSRP version 1 uses UDP port number 1985 and multicast address 224.0.0.2 and version 2 uses UDP port 1985 and 224.0.0.102 as multicast address. preempt has to be enabled manually.
What is HSRP (hot standby Router Protocol)?
HSRP (Hot Standby Router Protocol) is a Cisco proprietary First Hop Redundancy Protocol (FHRP). HSRP first hop redundancy mechanism provides alternative path as a proactive action for any failure on a device.
What is the HSRP version 2 packet format?
HSRP version 2 uses the new IP multicast address 224.0.0.102 to send hello packets instead of the multicast address of 224.0.0.2, which is used by version 1. HSRP version 2 packet format includes a 6-byte identifier field that is used to uniquely identify the sender of the message. Typically, this field is populated with the interface MAC address.
