VRRP Virtual Router configuration
Virtual Router commands are used for configuring virtual routers for this switch. A virtual router is defined by its virtual router ID and an IP address. On each
Virtual routers are disabled by default.
The following table describes the Virtual Router Configuration commands. Table 148 Virtual Router Configuration commands
Command | Description |
|
|
Defines the virtual router ID. This is used in conjunction with addr (below) to | |
| define a virtual router on this switch. To create a pool of |
| routing devices which can provide redundancy to each other, each |
| participating VRRP device must be configured with the same virtual router: |
| one that shares the same virtual router ID and address |
| combination. |
| The vrid for standard virtual routers (where the virtual router IP address is |
| not the same as any virtual server) can be any integer between 1 and 250. |
| The default value is 1. |
| All virtual router ID values must be unique within the VLAN to which |
| the virtual router’s IP interface belongs. |
| Command mode: Router VRRP |
|
|
[no] | Defines the IP address for this virtual router using dotted decimal notation. |
address <IP address> | This is used in conjunction with the vrid (above) to configure the same |
| virtual router on each participating VRRP device. The default address is |
| 0.0.0.0. |
| Command mode: Router VRRP |
|
|
Selects a switch IP interface. If the IP interface has the same IP address as | |
interface | the address option above, this switch is considered the “owner” of the |
| defined virtual router. An owner has a special priority of 255 (highest) and |
| will always assume the role of master router, even if it must preempt another |
| virtual router which has assumed master routing authority. This preemption |
| occurs even if the preemption option below is disabled. |
| The default value is 1. |
| Command mode: Router VRRP |
|
|
Defines the election priority bias for this virtual server. This can be any | |
priority | integer between 1 and 254. The default value is 100. |
| During the master router election process, the routing device with the highest |
| virtual router priority number wins. If there is a tie, the device with the |
| highest IP interface address wins. If this virtual router’s IP address is the |
| same as the one used by the IP interface, the priority for this virtual router |
| will automatically be set to 255 (highest). |
| When priority tracking is used, this base priority value can be modified |
| according to a number of performance and operational criteria. |
| Command mode: Router VRRP |
|
|
Defines the time interval between VRRP master advertisements. This can be | |
timers advertise | any integer between 1 and 255 seconds. The default value is 1. |
