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.
Hewlett-Packard recommends that you do not use more than one redundancy protocol (VRRP, VRRPE, or SRP)
on the same device.
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)
based on RFC 2338 or VRRP-Extended, HP’s
enhanced implementation of VRRP
Disabled
Note: nly one of the
protocols can be
enabled at a time.

VRRP or
VRRPE router
The HP routing switch’s active participation as a
VRRP or VRRPE router. abling 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
ID (VRID)
The ID of the virtual router you are creating by
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.
