enabled and Down if the virtual router is disabled.
Priority Displays the priority of the virtual router. A higher priority will increase the probability
that this router will become the Master router of the group. A lower priority will
increase the probability that this router will become the backup router. The lower the
number, the higher the priority.
Master IP Address Displays the IP address of the Master router for the VRRP function.
Critical IP Address Displays the critical IP address of the VRRP function. This address will judge if a
virtual router is qualified to be a master router.

IP Multicast
Controlling Multicast Routing on the Switch includes setting up IGMP for IP interfaces, PIM and DVMRP. This chapter
describes how to set these up. For an explanation of how these protocols function, read Appendix C.
IGMP Interface Settings
IGMP for IP interfaces function the same way they do for individual ports or VLANs in Layer 2. Most of the parameters
are the same as well, except instead of configuring for VLANs you are setting up IGMP for different subnets (IP
interfaces).
The IGMP interface links are located in the IP Multicast subfolder in the Layer 3 IP Networking configuration folder.
