RFC 3768 Title: Virtual Router Redundancy Protocol (VRRP) Author(s): R. Hinden, Ed. Status: Standards Track Date: April 2004 Mailbox: bob.hinden@nokia.com Pages: 27 Characters: 59969 Obsoletes: 2338 I-D Tag: draft-ietf-vrrp-spec-v2-10.txt URL: ftp://ftp.rfc-editor.org/in-notes/rfc3768.txt This memo defines the Virtual Router Redundancy Protocol (VRRP). VRRP specifies an election protocol that dynamically assigns responsibility for a virtual router to one of the VRRP routers on a LAN. The VRRP router controlling the IP address(es) associated with a virtual router is called the Master, and forwards packets sent to these IP addresses. The election process provides dynamic fail over in the forwarding responsibility should the Master become unavailable. This allows any of the virtual router IP addresses on the LAN to be used as the default first hop router by end-hosts. The advantage gained from using VRRP is a higher availability default path without requiring configuration of dynamic routing or router discovery protocols on every end-host. This document is a product of the Virtual Router Redundancy Protocol Working Group of the IETF. This is now a Draft Standard Protocol. This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited. This announcement is sent to the IETF list and the RFC-DIST list. Requests to be added to or deleted from the IETF distribution list should be sent to IETF-REQUEST@IETF.ORG. Requests to be added to or deleted from the RFC-DIST distribution list should be sent to RFC-DIST-REQUEST@RFC-EDITOR.ORG.

When a VRRP Master comes up, Section 6.4.1 Initialize, o Broadcast a gratuitous ARP request containing the virtual router MAC address for each IP address associated with the virtual router. Also Section 6.4.2 Backup - If the Master_Down_Timer fires, then: o Send an ADVERTISEMENT o Broadcast a gratuitous ARP request containing the virtual router MAC address for each IP address associated with the virtual router - Is it the MAC braodcasted is Virtual MAC associated with the Virtual IP address ?? or Physical MAC associated with Virtual IP physical interface . If the Client host is holding Virtual MAC associated with the Virtual IP.. there is no need to send the GARP message in the first place. I beleive the virtual MAC is calculated from the Virtual IP address, something similar to Multicast MAC calculation form multicast address. During ARP form the Client Host to the Router on virtual IP, ARP replies with the virtual MAC for the virtual IP and not the physical MAC associated with the virtual ip address. In that case, we needn't bother about the GARP and any intermediate routers between the VRRP router and client host. Because, some cases routers will block boardcast packets to get propagated on other subnet, here GARP is a broadcast packet.

I guess we should have been more consistent in using the term VMAC throughout the spec since that's well defined and less ambiguous. so ARP packet 'sender harware address' =3D VMAC and 'sender protocol address' =3D VIP. > If the Client host is holding Virtual MAC associated > with the Virtual IP.. > there is no need to send the GARP message in the > first place.=20 your interpretation is correct; within the vrrp protocol there is absolutely no requirement / reliance on ARP. that was part of the [often controversial] design decision to go with VMAC. the whole gratuitous ARP thing is more related to smoothing initial transition from non-VRRP operation to VRRP. if you've deployed your network and have hosts with the default router physical=20 IP+MAC mapping in place and then you switch on VRRP operation the gratuitous ARP is to hopefully speed the switchover of those hosts. within the VRRP spec it was just easier to say 'always send gratuitous ARP when a Master comes up' than to try and figure out some robust mechanism to detect just the case of the first Master transition when VRRP is first enabled on the LAN. cheers,danny =09 =09 __________________________________ Do you Yahoo!?

L2 switches that partition=20 station learning cache and other state per-VLAN have no issues. L2 switches that use a global station learning cache across all VLAN don't like this VRRP feature. in those deployment the administrator needs to assign a different VRID to virtual routers across all VLANs. =09 =09 __________________________________ Do you Yahoo!?

I'm not sure what you mean by 'there is always a problem' when vrrp is deployed with L2 switch/bridge? I did mention the one confirmed problem I've heard of=20 related to L2 switch implementing multiple logical L2=20 (VLANs) within a single switch. but for the standard=20 L2 switch/bridge implementing a single LAN across all=20 ports there should be no significant issues and correct protocol operation has been demonstrated in many real deployments. there is an interaction with station learning cache on vrrp=20 master failover if the routers are connected to different ports. but that update is covered by the=20 vrrp protocol (via heartbeat using MAC.src=3DVMAC) and I wouldn't classify it as a 'problem'. =20 I've heard rumors of issues/interactions related to mostly non-standardized vendor 'value added features'. e.g. locking a port down to a specific MAC address for security/access control. some rumors about=20 interactions with spanning tree loop detection when a=20 MAC changes port. etc. but I'm not sure if those have been confirmed/documented? =09 =09 __________________________________ Do you Yahoo!?

In your diagram, the virtual MAC is still (and always) calculated from the VRID. It is pretty much normal that different IP addresses are mapped to the same MAC. Note that MAC is used for L2 encapsulation, but not for IP forwarding. When forwarding an IP packet, the host/router needs to find out the next-hop interface, next-hop IP address, etc from its routing table. After the next-hop IP address (in this diagram, it will be either IP-A or IP-C)is found, the MAC address is used for the encapsulation in the L2 header, and then the IP packet is forwarded out of the next-hop interface. Hope it helps.
