short_description: Manages a VRF for an OSPF router.
description:
- Manages a VRF for an OSPF router.
author: Gabriele Gerbino (@GGabriele)
notes:
- Value I(default) restores params default value, if any.
Otherwise it removes the existing param configuration.
options:
vrf:
description:
- Name of the resource instance. Valid value is a string.
The name 'default' is a valid VRF representing the global OSPF.
required: false
default: default
ospf:
description:
- Name of the OSPF instance.
required: true
default: null
router_id:
description:
- Router Identifier (ID) of the OSPF router VRF instance.
required: false
default: null
default_metric:
description:
- Specify the default Metric value. Valid values are an integer
or the keyword 'default'.
required: false
default: null
log_adjacency:
description:
- Controls the level of log messages generated whenever a
neighbor changes state. Valid values are 'log', 'detail',
and 'default'.
required: false
choices: ['log','detail','default']
default: null
timer_throttle_lsa_start:
description:
- Specify the start interval for rate-limiting Link-State
Advertisement (LSA) generation. Valid values are an integer,
in milliseconds, or the keyword 'default'.
required: false
default: null
timer_throttle_lsa_hold:
description:
- Specify the hold interval for rate-limiting Link-State
Advertisement (LSA) generation. Valid values are an integer,
in milliseconds, or the keyword 'default'.
required: false
default: null
timer_throttle_lsa_max:
description:
- Specify the max interval for rate-limiting Link-State
Advertisement (LSA) generation. Valid values are an integer,
in milliseconds, or the keyword 'default'.
required: false
default: null
timer_throttle_spf_start:
description:
- Specify initial Shortest Path First (SPF) schedule delay.
Valid values are an integer, in milliseconds, or
the keyword 'default'.
required: false
default: null
timer_throttle_spf_hold:
description:
- Specify minimum hold time between Shortest Path First (SPF)
calculations. Valid values are an integer, in milliseconds,
or the keyword 'default'.
required: false
default: null
timer_throttle_spf_max:
description:
- Specify the maximum wait time between Shortest Path First (SPF)
calculations. Valid values are an integer, in milliseconds,
or the keyword 'default'.
required: false
default: null
auto_cost:
description:
- Specifies the reference bandwidth used to assign OSPF cost.
Valid values are an integer, in Mbps, or the keyword 'default'.
required: false
default: null
