Configuring VRRP and VRRPE
Master and Backups
•VRRP – The “Owner” of the IP address of the VRID is the default Master and has the highest priority (255). The precedence of the Backups is determined by their priorities. The default Master is always the Owner of the IP address of the VRID.
•VRRPE – The Master and Backups are selected based on their priority. You can configure any of the routing switches to be the Master by giving it the highest priority. There is no Owner.
•SRP – You can configure one Primary Router and one Backup Router. There is no Owner. You must define the virtual IP address (the one you are backing up) on both the Primary Router and the Backup Router.
NOTE: If your HP routing switches already are using SRP and you do not need redundancy with devices that cannot use SRP, you do not need to reconfigure your routers to use VRRP or VRRPE.
VRRP and VRRPE Parameters
Table 12.1 lists the VRRP and VRRPE parameters. Most of the parameters and default values are the same for both protocols. The exceptions are noted in the table.
Table 12.1: VRRP and VRRPE Parameters
Parameter | Description | Default | See page... |
|
|
|
|
Protocol | The Virtual Router Redundancy Protocol (VRRP) | Disabled | |
| based on RFC 2338 or | Note: Only one of the | |
| enhanced implementation of VRRP | ||
| protocols can be |
| |
|
|
| |
|
| enabled at a time. |
|
|
|
|
|
VRRP or | The HP routing switch’s active participation as a | Inactive | |
VRRPE router | VRRP or VRRPE router. Enabling the protocol does |
| |
| not activate the routing switch for VRRP or VRRPE. |
| |
|
|
| |
| You must activate the device as a VRRP or VRRPE |
|
|
| router after you configure the VRRP or VRRPE |
|
|
| parameters. |
|
|
|
|
|
|
Virtual Router | The ID of the virtual router you are creating by | None | |
ID (VRID) | configuring multiple routers to back up an IP interface. |
| |
| You must configure the same VRID on each router |
| |
|
|
| |
| that you want to use to back up the address. |
| |
| No default. |
