Is HSRP compatible with VRRP?
VRRP is based on Cisco’s proprietary Hot Standby Router Protocol (HSRP) concepts. The protocols, while similar in concept, are not compatible. An ARP request to an HSRP or VRRP virtual IP address will be replied to with the virtual MAC address, so that hosts can send traffic to the active group member.
What is the difference between VRRP and HSRP?
Hot Standby Router Protocol (HSRP) is a CISCO proprietary protocol used to provide redundancy in a network. Virtual Router Redundancy Protocol (VRRP) is an open standard protocol used to provide redundancy in a network. VRRP is a network layer protocol.
Is HSRP a Layer 2 protocol?
Hot Standby Router Protocol (HSRP) is a Cisco proprietary protocol that allows several routers or multilayer switches to appear as a single gateway IP address. It provides redundancy for the layer 3 functions in our networks. They use ARP to acquire the layer 2 address of the default gateway.
Why would you choose to use VRRP instead of HSRP?
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.
What is VSS in Nexus?
VSS (Virtual Switching System) Compared to the vPC feature of the Nexus, the unified control plane aspect of VSS mode allows for the full system capabilities to be used on a multi-chassis EtherChannel, so L3 EtherChannels, MPLS awareness, full QoS capabilities, and other features are usable across both of the systems.
Which behavior can be expected when the HSRP version is changed from 1 to 2?
Which behavior can be expected when the HSRP version is changed from 1 to 2? A. No changes occur because the standby router is upgraded before the active router.
What is valid HSRP virtual MAC address?
Virtual MAC address : MAC address is generated automatically by HSRP. The first 24 bits will be default CISCO address (i.e. 0000.0c). The next 16 bits are HSRP ID (i.e. 07.ac). The next 8 bits will be the group number in hexadecimal.
What’s the difference between a VRRP and a HSRP?
With HSRP, each interface must have an IP address that is separate from the HSRP group address. VRRP lets you share the Master’s interface IP address. On Cisco devices, VRRP is configured to preempt by default, whereas HSRP is not configured to preempt by default.
Which is better VRRP or GLBP redundancy protocols?
VRRP is an IETF standard (RFC 3768) so it is supported by all router vendors. If you have a mixed vendor environment (e.g Cisco, Juniper etc) than its better to use VRRP. All protocols support more than 2 routers in a group. All protocols support tracking.
Is the VRRP protocol compatible with IPv6?
No support for IPv6 on the original VRRP implementation. However, VRRPv3 (RFC 5798) now supports it. If your network contains only Cisco devices, then I suggest to use HSRP. It works pretty well and is well supported.
Which is better for load balancing GLBP or HSRP?
GLBP is the only one which provides load balancing of traffic among the devices in the group. HSRP and GLBP are Cisco proprietary. VRRP is an IETF standard (RFC 3768) so it is supported by all router vendors. If you have a mixed vendor environment (e.g Cisco, Juniper etc) than its better to use VRRP.
