NETGEAR 8800 User Manual • A maximum of 128 VRID instances are supported on the router. • Up to seven unique VRIDs can be configured on the router. VRIDs can be re-used, but not on the same interface. • VRRP and the Spanning Tree Protocol (STP) can be simultaneously enabled on the same switch. • When VRRP and BOOTP/DHCP relay are both enabled on the switch, the relayed BOOTP agent IP address is the actual switch IP address, not the virtual IP address. • It is possible to assign multiple virtual IP addresses to the same VRID for a VRRP VR. In this case, you must meet the following conditions: • Multiple virtual IP addresses must be on the same subnet. • The switch cannot own any of the multiple IP addresses. For example, if you have a VLAN named v1 configured with IP addresses 1.1.1.1/24 and 2.2.2.2/24, the following configurations are allowed: • VRRP VR on VLAN v1 with VRID 99 with virtual IP addresses 1.1.1.2 and 1.1.1.3 • VRRP VR on VLAN v1 with VRID 99 with virtual IP addresses 1.1.1.98 and 1.1.1.99 Using the VLAN v1 configuration described above, the following configurations are not allowed: • VRRP VR on VLAN v1 with VRID 99 with virtual IP addresses 1.1.1.1 and 2.2.2.2 (the IP addresses are not on the same subnet). • VRRP VR on VLAN v1 with VRID 99 with virtual IP addresses 1.1.1.1 and 1.1.1.99 (the switch owns IP address 1.1.1.1). VRRP Configuration Parameters Table 56 lists the parameters that you can configure on a VRRP router. Table 56. VRRP Configuration Parameters Parameter vrid priority Description This is the virtual router identifier and is a configured item in the range of 1 to 255. This parameter has no default value. For more information, see the create vrrp vlan vrid command. This priority value to be used by this VRRP router in the master election process. A value of 255 is reserved for a router that is configured with the virtual router IP address. A value of 0 is reserved for the master router to indicate it is releasing responsibility for the virtual router. The range is 1 to 254. The default value is 100. For more information, see the configure vrrp vlan vrid priority command. 586 | Chapter 19. VRRP
