FREEVRRPD(8) NetBSD System Manager's Manual FREEVRRPD(8) NNAAMMEE ffrreeeevvrrrrppdd - Virtual Redundancy Router Protocol Daemon SSYYNNOOPPSSIISS ffrreeeevvrrrrppdd [--FF] [--ff _c_o_n_f_i_g___f_i_l_e] [--cc _c_h_r_o_o_t___d_i_r_e_c_t_o_r_y] DDEESSCCRRIIPPTTIIOONN ffrreeeevvrrrrppdd is a RFC2338 compliant daemon, you can use VRRP protocol with multiple interfaces and multiple VRID. For each VRID defined in the con- figuration file, ffrreeeevvrrrrppdd create a thread for managing a poll of one or multiple virtual IP addresses. Thios daemon work only in IPv4 environ- nement and not in IPv6 yet. you can eliminate all point of failures of your network with this util- ity. When ffrreeeevvrrrrppdd is started, it reads /usr/local/etc/freevrrpd.conf file and go to background. All options are defined in this file. For more informations, you can read comments on this file or go to configuration section. ffrreeeevvrrrrppdd iiss ccoommppaattiibbllee wwiitthh FFrreeeeBBSSDD,, NNeettBBSSDD aanndd OOppeennBBSSDD.. List of functionnalities : ++oo Support of multiples VRID ++oo Master announce state by sending multicast packets via BPF device ++oo Changing routes and IP in 3 seconds ++oo Doing gratuitous ARP requests to clean the ARP cache of all hosts ++oo Election between differents SLAVE servers with differents priorities ++oo Same host can be a SLAVE and MASTER at the same time for different VRID ++oo Autmatic downgrade to SLAVE state if a MASTER is up again ++oo Support of plain text authentication described in RFC2338 ++oo Support netmask for virtual IP addresses CCOONNFFIIGGUURRAATTIIOONN ffrreeeevvrrrrppdd reads configuration data from /usr/local/etc/freevrrpd.conf (or the file specified with -f on the command line). The file contains key- word-argument pairs, one per line. Each VRID definition is define by the [VRID] keyword. Lines statring with '#' and empty lines are interpreted as comments. The possible keywords and their meanings are as follows (note that key- words and arguments are cas-sensitive): sseerrvveerriidd This keyword is followed by a decimal number between 1 and 255 and represent the group identifier (Virtual Router Identifier). iinntteerrffaaccee This keyword is followed by an interface name where multicast VRRP annonce on the specified serverid group will be sent. uusseeVVMMAACC Specifies wheter Virtual MAC adress (like 00:5E:00:...) is per- mitted. The default is ``yes''. Note that disabling useVMAC is a RFC infragment but must be necessary for some specific cases. If disabled, ``sendgratuitousarp'' must be enabled. pprriioorriittyy This keyword can be followed by a decimal number between 0 to 255. a priority of 255 mean a MASTER server. a priority between 0 to 254 is a BACKUP priority. Note that 0 is the minimal BACKUP priority and 254 is the higher. If the VRID MASTER fail, tha higher BACKUP priority will become MASTER. aaddddrr Specifies all Virtual IP adresses separated by commas of the cor- responded VRID. a VIP syntax will be: ``xxx.xxx.xxx.xxx/yy'' or ``device:xxx.xxx.xxx.xxx/yy.'' ``xxx.xxx.xxx.xxx'' represent the IP adress and ``yy'' is a netmask in CIDR format. device is an optional device where VIP will be setted. mmoonniittoorreeddcciirrccttuuiiss Specifies whether NIC monitoring is enabled. This option use a special ioctl for getting carrier, duplex and health of the net- work card. The default is ``yes''. Note that your NIC driver must support mii bus functionnality. Some old drivers cannot use this option and must be disabled. MMCCCClleeaarrEErrrroorrssCCoouunntt This keyword can be followed by a decimal number that represent the number of concurrent valid checks (monitored circuits) before nberrors flag will be resetted at 0. The default is ``3600''. Note that the default value mean that 30 concurrent checks ok on a NIC by monitored circuits will reset the error counter for this NIC. If a value of mmaasstteerrssccrriipptt This keyword can be followed by a script name with an absolute path and will be executed during MASTER transition state. bbaacckkuuppssccrriipptt This keyword take same argument as ``masterscript'' except that this script is executed during BACKUP transition state. vvrriiddssddeepp This keyword can be followed by a list of VRID in decimal format separated by commas and depends from this one. If this VRID become BACKUP, all VRIDs specified will become BACKUP too. ppaasssswwoorrdd This keyword can be followed by a password for authenticate VRRP packets on a specific VRID. Note that the password will be transmitted in clear with this method.

If you want to stop freevrrpd, you can use kill [PID] and not kill -9 [PID], then it can delete virtual IP addresses and routes properly on shutdown.
