446 BigIron RX Series Configuration Guide53-1001810-01VRRP and VRRPE parameters17Router1 is the master for VRID 1 (backup priority = 110) and Router2 is the backup for VRID 1(backup priority = 100). Router1 and Router2 both track the uplinks to the Internet. If an uplinkfailure occurs on Router1, its backup priority is decremented by 20 (track priority = 20), so that alltraffic destined to the Internet is sent through Router2 instead.Similarly, Router2 is the master for VRID 2 (backup priority = 110) and Router1 is the backup forVRID 2 (backup priority = 100). Router1 and Router2 are both tracking the uplinks to the Internet.If an uplink failure occurs on Router2, its backup priority is decremented by 20 (track priority = 20),so that all traffic destined to the internet is sent through Router1 instead.The device configured for VRRPE can interoperate only with other device.VRRP and VRRPE parametersTable 84 lists the VRRP and VRRPE parameters. Most of the parameters and default values are thesame for both protocols. The exceptions are noted in the table.TABLE 84 VRRP and VRRPE parametersParameter Description Default See page...Protocol The Virtual Router Redundancy Protocol (VRRP) based on RFC2338 or VRRP-Extended, Brocade’s enhanced implementation ofVRRPDisabledNOTE: Only one of theprotocols can beenabled at a time.page 448page 450VRRP or VRRPErouterThe device’s active participation as a VRRP or VRRPE router.Enabling the protocol does not activate the device for VRRP orVRRPE. You must activate the device as a VRRP or VRRPE routerafter you configure the VRRP or VRRPE parameters.Inactive page 448page 450Virtual Router ID(VRID)The ID of the virtual router you are creating by configuring multiplerouters to back up an IP interface. You must configure the sameVRID on each router that you want to use to back up the address.No default.None page 448page 450Virtual Router IPaddressThis is the address you are backing up.No default.• VRRP – The virtual router IP address must be a real IPaddress configured on the VRID interface on one of the VRRProuters. This router is the IP address Owner and is thedefault Master.• VRRPE – The virtual router IP address must be in the samesubnet as a real IP address configured on the VRRPEinterface, but cannot be the same as a real IP addressconfigured on the interface.None page 448page 450VRID MAC address The source MAC address in VRRP or VRRPE packets sent from theVRID interface, and the destination for packets sent to the VRID.• VRRP – A virtual MAC address defined as00-00-5e-00-01-. The Master owns the Virtual MACaddress.• VRRPE – A virtual MAC address defined as02-E0-52--, where is atwo-octet hashed value for the IP address and is theVRID.Not configurable page 442
