Example: Configuring Multiple VRRP Owner Groups

Requirements

• 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.

Configuration

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.

Configuring multiple IPv4 owner groups

Step-by-Step Procedure

1. Create an IPv4 interface on the device
   [edit]user@host# edit interfaces ge-1/0/0 unit 0 family inet
2. Configure the first IPv4 owner group
   [edit interfaces ge-1/0/0 unit 0 family inet]user@host# set address 10.0.0.2/24 vrrp-group 2 virtual-address 10.0.0.4 accept-data
3. Configure the second IPv4 owner group
   [edit interfaces ge-1/0/0 unit 0 family inet]user@host# set address 20.0.0.2/24 vrrp-group 3 virtual-address 20.0.0.2 priority 255
4. Configure the third IPv4 owner group
   [edit interfaces ge-1/0/0 unit 0 family inet]user@host# set address 30.0.0.2/24 vrrp-group 4 virtual-address 30.0.0.2 priority 255

Configuring multiple IPv6 owner groups

Step-by-Step Procedure

1. Create an IPv6 interface on the device
   [edit]user@host# edit interfaces ge-1/0/0 unit 0 family inet6
2. Configure the inet6 address for the first IPv6 owner group
   [edit interfaces ge-1/0/0 unit 0 family inet6]user@host# set address 2001:4818:f000:20::1/64 vrrp-inet6-group 1 virtual-inet6-address 2001:4818:f000:20::1
3. [edit interfaces ge-1/0/0 unit 0 family inet6]user@host# set address 2001:4818:f000:20::1/64 vrrp-inet6-group 1 virtual-link-local-address fe80:4818:f000:20::1
4. [edit interfaces ge-1/0/0 unit 0 family inet6]user@host# set address 2001:4818:f000:20::1/64 vrrp-inet6-group 1 priority 255
5. [edit interfaces ge-1/0/0 unit 0 family inet6]user@host# set family inet6 address 2001:1000:f000:20::1/64 vrrp-inet6-group 2 virtual-inet6-address 2001:1000:f000:20::1
6. [edit interfaces ge-1/0/0 unit 0 family inet6]user@host# set family inet6 address 2001:1000:f000:20::1/64 vrrp-inet6-group 2 virtual-link-local-address fe80:1000:f000:20::1
7. [edit interfaces ge-1/0/0 unit 0 family inet6]user@host# set family inet6 address 2001:1000:f000:20::1/64 vrrp-inet6-group 2 priority 255
8. [edit interfaces ge-1/0/0 unit 0 family inet6]user@host# set family inet6 address 2001:2000:f000:20::1/64 vrrp-inet6-group 3 virtual-inet6-address 2001:2000:f000:20::2
9. [edit interfaces ge-1/0/0 unit 0 family inet6]user@host# set family inet6 address 2001:2000:f000:20::1/64 vrrp-inet6-group 3 virtual-link-local-address fe80:2000:f000:20::2
10. [edit interfaces ge-1/0/0 unit 0 family inet6]user@host# set address 2001:2000:f000:20::1/64 vrrp-inet6-group 3 priority 250

Configuring multiple IPv4 and IPv6 owner groups

Step-by-Step Procedure

1. Create an interface on the device
   [edit]user@host# edit interfaces ge-1/0/0 unit 0
2. Configure the family inet address and virtual address for the IPv4 owner group
   [edit interfaces ge-1/0/0 unit 0]user@host# set family inet address 10.0.0.1/24 vrrp-group 5 virtual-address 10.0.0.1
3. Set the priority of the IPv4 owner group to 255
   [edit interfaces ge-1/0/0 unit 0]set family inet address 10.0.0.1/24 vrrp-group 5 priority 255
4. Configure the inet6 address for the first IPv6 owner group
   [edit interfaces ge-1/0/0 unit 0]set family inet6 address 2001:4818:f000:20::1/64 vrrp-inet6-group 1 virtual-inet6-address 2001:4818:f000:20::1
5. Set the virtual link local address for the first IPv6 owner group
   [edit interfaces ge-1/0/0 unit 0]set family inet6 address 2001:4818:f000:20::1/64 vrrp-inet6-group 1 virtual-link-local-address fe80:4818:f000:20::1
6. Set the first IPv6 owner group’s priority to 255
   [edit interfaces ge-1/0/0 unit 0]set family inet6 address 2001:4818:f000:20::1/64 vrrp-inet6-group 1 priority 255
7. Configure the inet6 address for the second IPv6 owner group
   [edit interfaces ge-1/0/0 unit 0]set family inet6 address 2001:1000:f000:20::1/64 vrrp-inet6-group 2 virtual-inet6-address 2001:1000:f000:20::1
8. Set the virtual link local address for the second IPv6 owner group
   [edit interfaces ge-1/0/0 unit 0]set family inet6 address 2001:1000:f000:20::1/64 vrrp-inet6-group 2 virtual-link-local-address fe80:1000:f000:20::1
9. Set the second IPv6 owner group’s priority to 255
   [edit interfaces ge-1/0/0 unit 0]set family inet6 address 2001:1000:f000:20::1/64 vrrp-inet6-group 2 priority 255
10. Configure the inet6 address for the third IPv6 owner group
    [edit interfaces ge-1/0/0 unit 0]set family inet6 address 2001:2000:f000:20::1/64 vrrp-inet6-group 3 virtual-inet6-address 2001:2000:f000:20::2
11. Set the virtual link local address for the third IPv6 owner group
    [edit interfaces ge-1/0/0 unit 0]set family inet6 address 2001:2000:f000:20::1/64 vrrp-inet6-group 3 virtual-link-local-address fe80:2000:f000:20::2
12. Set the third IPv6 owner group’s priority to 250
    [edit interfaces ge-1/0/0 unit 0]set family inet6 address 2001:2000:f000:20::1/64 vrrp-inet6-group 3 priority 250

Verification

To verify the configuration, run the show interfaces ge-1/0/0 command, or use whichever name you assigned to the interface.
