module: bigip_message_routing_peer
short_description: Manage peers for routing generic message protocol messages
description:
- Manage peers for routing generic message protocol messages.
version_added: 2.9
options:
name:
description:
- Specifies the name of the peer to manage.
type: str
required: True
description:
description:
- The user defined description of the peer.
type: str
type:
description:
- Parameter used to specify the type of the peer to manage.
- Default setting is C(generic) with more options added in future.
type: str
choices:
- generic
default: generic
auto_init:
description:
- If C(yes), the BIGIP will automatically create outbound connections to the active pool members in the
specified C(pool) using the configuration of the specified C(transport_config).
- For auto-initialization to attempt to create a connection, the peer must be included in a route that is attached
to a router instance. For each router instance that the peer is contained in, a connection will be initiated.
- The C(auto_init) logic will verify at C(auto_init_interval) if the a connection exists between
the BIG-IP and the pool members of the pool. If a connection does not exist, it will attempt to reestablish one.
type: bool
auto_init_interval:
description:
- Specifies the interval that attempts to initiate a connection occur.
- The default value upon peer object creation, that supplied by the system is C(5000) milliseconds.
- The accepted range is between 0 and 4294967295 inclusive.
type: int
connection_mode:
description:
- Specifies how the number of connections per host are to be limited.
type: str
choices:
- per-blade
- per-client
- per-peer
- per-tmm
number_of_connections:
description:
- Specifies the distribution of connections between the BIG-IP and a remote host.
- The accepted range is between 0 and 65535 inclusive.
type: int
pool:
description:
- Specifies the name of the pool that messages will be routed towards.
- The specified pool must be on the same partition as the peer.
type: str
ratio:
description:
- Specifies the ratio to be used for selection of a peer within a list of peers in a ltm route.
- The accepted range is between 0 and 4294967295 inclusive.
type: int
transport_config:
description:
- The name of the ltm virtual or ltm transport-config to use for creating an outgoing connection.
- The resource must exist on the same partition as the peer object.
type: str
partition:
description:
- Device partition to create peer object on.
type: str
default: Common
state:
description:
- When C(present), ensures that the peer exists.
- When C(absent), ensures the peer is removed.
type: str
choices:
- present
- absent
default: present
notes:
- Requires BIG-IP >= 14.0.0
