Example: Configuring Multiple VRRP Owner Groups
These examples show how to configure multiple virtual router redundancy protocol (VRRP) IPv4 and IPv6 owner groups.
Requirements
This example uses the following hardware and software components:
A EX-Series, M-Series, MX-Series, or T-Series router.
Junos OS release 12.3 or later
Overview
Multiple VRRP owner groups allows users to reuse interface address identifiers (IFAs) as virtual IP addresses (VIPs). You can configure multiple IPv4 owner groups, multiple IPv6 owner groups, or a mix of IPv4 and IPv6 owner groups.

CLI Quick Configuration
To quickly configure this section of the example,
copy the following commands, paste them into a text file, remove any
line breaks, change any details necessary to match your network configuration,
and then copy and paste the commands into the CLI at the [edit] hierarchy level.
