Chapter 20 Configuring VRRP
Configuring VRRP
Configuring VRRP Groups
You can create a VRRP group, assign the virtual IP address, and enable the group.
You can configure one virtual IPv4 address for a VRRP group. By default, the master VRRP router drops
the packets addressed directly to the virtual IP address because the VRRP master is only intended as a
next-hop router to forward packets. Some applications require that Cisco NX-OS accept packets
addressed to the virtual router IP. Use the secondary option to the virtual IP address to accept these
packets when the local router is the VRRP master.
Once you have configured the VRRP group, you must explicitly enable the group before it becomes
active.
BEFORE YOU BEGIN
Ensure that you are in the correct VDC (or use the switchto vdc command).
Ensure that you configure an IP address on the interface (see the “Configuring IPv4 Addressing” section
on page 2-7.
