Due to high cpu usage problem, I'm switch to CHR.

Before that, I installed ROS 6.38.1 in a VM of VMware Workstation, and VRRP worked well.

And I change to use CHR 6.38.1 and also install VM on same VMware Workstation.

Basically the ROS VM and CHR VM are same, but on CHR, VRRP cannot be ready.

What's the problem?

OK, I figured out the problem. The CHR doesn't support IPv6, so I have to use IPv4 for VRRP and set fake ip address on VRRP.
