VRRP role

This role facilitates configuring virtual router redundancy protocol (VRRP) attributes. It supports the creation of VRRP groups for interfaces and setting the VRRP group attributes. This role is abstracted for Dell EMC PowerSwitch platforms running Dell EMC SmartFabric OS10.

The VRRP role requires an SSH connection for connectivity to a Dell EMC SmartFabric OS10 device. You can use any of the built-in OS connection variables.

Role variables

  • Role is abstracted using the ansible_network_os variable that can take dellemc.os10.os10 as the value
  • If os10_cfg_generate is set to true, the variable generates the role configuration commands in a file
  • Any role variable with a corresponding state variable set to absent negates the configuration of that variable
  • Setting an empty value for any variable negates the corresponding configuration
  • os10_vrrp (dictionary) holds a dictionary with the interface name key
  • Interface name can correspond to any of the valid OS10 interface with a unique interface identifier name
  • Physical interfaces names must be in format (for example fortyGigE 1/1)
  • Variables and values are case-sensitive
Key Type Description Support
vrrp dictionary Configures VRRP commands (see vrrp.*) os10
version dictionary Configures VRRP version os10
vrrp_active_active_mode dictionary Configures VRRP active-active mode os10
delay_reload integer Configures the minimum delay timer applied after boot (0 to 900) os10
vrrp_group list Configures VRRP group commands (see vrrp_group.*) os10
vrrp_group.type string: ipv6,ipv4 Specifies the type of the VRRP group os10
vrrp_group.group_id integer (required) Configures the ID for the VRRP group (1 to 255) os10
vrrp_group.virtual_address string Configures a virtual-address to the VRRP group (A.B.C.D format) os10
virtual_address.ip string Configures a virtual ip address (A.B.C.D format) os10
virtual_address.state string: present*,absent Configures/unconfigures a virtual-address (A.B.C.D format) os10
vrrp_group.preempt boolean: true*,false Configures preempt mode on the VRRP group os10
vrrp_group.priority integer Configures priority for the VRRP group (1 to 255; default 100) os10
vrrp_group.adv_interval_centisecs integer Configures the advertisement interval for the VRRP group in centiseconds (25 to 4075; default 100) and in multiple of 25; centisecs gets converted into seconds in version 2 os10
vrrp_group.track_interface list Configures the track interface of the VRRP group (see track.*) os10
track_interface.resource_id integer Configures the object tracking resource ID of the VRRP group; mutually exclusive with track.interface os10
track_interface.interface string Configures the track interface of the VRRP group ( format) os10
track_interface.priority_cost integer Configures the priority cost for track interface of the VRRP group (1 to 254; default 10) os10
track_interface.state string: present*,absent Deletes the specific track interface from the VRRP group if set to absent os10
vrrp_group.track_interface.state string: present*,absent Deletes all track interfaces from the VRRP group if set to absent os10
vrrp_group.state string: present*,absent Deletes the VRRP group from the interface if set to absent os10

NOTE: Asterisk (*) denotes the default value if none is specified.

Connection variables

Ansible Dell EMC network roles require connection information to establish communication with the nodes in your inventory. This information can exist in the Ansible group_vars or host_vars directories, or inventory or in the playbook itself.

Key Required Choices Description
ansible_host yes Specifies the hostname or address for connecting to the remote device over the specified transport
ansible_port no Specifies the port used to build the connection to the remote device; if value is unspecified, the ANSIBLE_REMOTE_PORT option is used; it defaults to 22
ansible_ssh_user no Specifies the username that authenticates the CLI login for the connection to the remote device; if value is unspecified, the ANSIBLE_REMOTE_USER environment variable value is used
ansible_ssh_pass no Specifies the password that authenticates the connection to the remote device
ansible_become no yes, no* Instructs the module to enter privileged mode on the remote device before sending any commands; if value is unspecified, the ANSIBLE_BECOME environment variable value is used, and the device attempts to execute all commands in non-privileged mode
ansible_become_method no enable, sudo* Instructs the module to allow the become method to be specified for handling privilege escalation; if value is unspecified, the ANSIBLE_BECOME_METHOD environment variable value is used
ansible_become_pass no Specifies the password to use if required to enter privileged mode on the remote device; if ansible_become is set to no this key is not applicable
ansible_network_os yes os10, null* Loads the correct terminal and cliconf plugins to communicate with the remote device

NOTE: Asterisk (*) denotes the default value if none is specified.

Example playbook

This example uses the os10_vrrp role to configure VRRP commands at the interfaces. It creates a hosts file with the switch details and corresponding variables. The hosts file should define the ansible_network_os variable with corresponding Dell EMC OS10 name.

When os10_cfg_generate is set to true, the variable generates the configuration commands as a .part file in build_dir path. By default, the variable is set to false. It writes a simple playbook that only references the os10_vrrp role.

Sample hosts file

leaf1 ansible_host= <ip_address>

Sample host_vars/leaf1
