Changing Vr Advertisement Interval And Source Ip Address - HP ProCurve 6200yl Multicast And Routing Manual

Virtual Router Redundancy Protocol (VRRP)
Configuring VRRP
6-22
Reconfiguring the Priority for a Backup. When you configure a Backup
in a VR, it is given a default priority of 100. This command is intended for use
where it is necessary to establish a precedence among the Backup routers on
the same network or subnet in a given VR.
Syntax: priority < 1 - 254 >
Used in a VR context of a VLAN where the router is configured
as a Backup. This command changes the Backup's priority
and is used to establish the precedence of a Backup where there
are multiple Backups belonging to the same network or subnet.
Also, the VR instance must be disabled (the default VR state)
when using this command.
Note: An Owner is automatically assigned the highest prior­
ity, 255, which cannot be changed unless the Owner status is
reconfigured to Backup.
(Range: 1 - 254, where 1 is the lowest precedence; Default: 100)

Changing VR Advertisement Interval and Source IP Address

The advertisement interval is used in one of two ways, depending on whether
a VRRP router is operating as a Master or a Backup.
Syntax: advertise-interval < 1 - 255 >
■ When a VRRP router is operating as Master, this value
specifies the interval at which the router sends an
advertisement notifying the other VRRP routers on the
network or subnet that a Master is active.
■ When a VRRP router is operating as a Backup, it uses
this value to calculate a timeout interval ( 3 x advt­
interval).
The VR instance must be disabled (the default VR state) when
using this command.
(Range: 1 - 255 seconds; Default: 1 second)
For information on advertisements and advertisement inter­
vals, see "Function of the VRRP Advertisement" on page 6-9
Note: All VRRP routers belonging to the same VR must be
configured with the same advertisement interval. As
required in RFC 3768, if a locally configured advertise­
ment interval does not match the interval received in an
inbound VRRP packet, then the VR drops that packet.
