Syntax: primary-ip-address < ip-address | lowest >
Specifies the virtual IP address to designate as the source for
VRRP advertisements from the VR. If there is only one virtual
IP address configured on the VR, the default setting (lowest)
is sufficient. Where there are multiple virtual IP addresses in
the same VR and you want to designate an advertisement
source other than the lowest IP Address, use this command.
For an Owner VR, the primary IP address must be one of the
virtual IP addresses configured on the VR. For a Backup VR,
the primary IP address must be in the same subnet as one of
the virtual IP addresses configured on the VR. In addition, the
primary IP address for a Backup VR must be one of the IP
addresses configured on the VLAN on which the VR is config­
ured.
The VR instance must be disabled (the default VR state) when
using this command.
(Default: lowest)
Note: It is common in VRRP applications to have only one
virtual IP address per VR. In such cases, the protocol
uses that address as the source IP address for VRRP
advertisements, and it is not necessary to specify an
address.
