Multicast and Routing Guide K/KA/KB.15.15
Dynamic priority change operating notes
• There are no backward compatibility issues with the VRRP dynamic priority change feature.
If a VRRP router has an older firmware version that does not have the dynamic priority change
feature, it will not have the needed configuration options.
• The VR's operating VLAN cannot be configured as a tracking VLAN for that VR.
• Ports that are part of a trunk cannot be tracked.
• A port that is tracked cannot be included in a trunk.
• Trunks that are tracked cannot be removed; you are not able to remove the last port from the
trunk.
• LACP (active or passive) cannot be enabled on a port that is being tracked.
• If a VLAN is removed or a port becomes unavailable, the configuration is retained and they
are tracked when they become available again.
• After the owner VR relinquishes control of its IP address, that IP address becomes unavailable
to all other applications and routing protocols such as RIP and OSPF .
• To avoid operational issues, HP recommends that VRRP is not run on the same interface/VLAN
with other routing protocols, such as RIP and OSPF.
