Configuring Router Priority In A Standby Group - 3Com 3C13636 Configuration Manual

3Com Router 3000 Ethernet Family
Configuration Guide
Note:
For the router, an interface can be assigned to 64 standby groups, each containing
up to 16 virtual IP addresses. When more than 14 VRRP standby groups are
present, you must enable promiscuous mode on interfaces to ensure connectivity of
direct routes, preventing packet drop when VRRP backup and load sharing are
used.
When the state of the VRRP standby group on the current router is master, its virtual
IP address in the standby group can be used as the source IP address for a GRE
channel or the local IP address for an IKE peer.

3.2.3 Configuring Router Priority in a Standby Group

In VRRP, the role that a router plays in a standby group depends on its priority. The
router with the highest priority becomes the master.
The priority is in the range 0 to 255, with a larger number indicating a higher priority.
However, the configurable range is 1 to 254. The priority 0 is reserved for special use
and 255 for the IP address owner.
Perform the following configuration in interface view.
Table 3-3 Configure the priority of the interface in the standby group
Configure the priority of the interface in
the standby group.
Restore the default value.
The priority defaults to 100. The higher the number, the higher the priority of the backup
interface.
Note:
The IP address owner has two priorities: configurable and operating. The configurable
priority is the one assigned using the vrrp vrid command and the operating priority is
always 255 and not configurable.
