The range is from 0 to 65535.

update_source

string

Source of the routing updates.

networks

list / elements=dictionary

Specify networks to announce via BGP.

For operation replace, this option is mutually exclusive with networks option under address_family.

For operation replace, if the device already has an address family activated, this option is not allowed.

masklen

integer / required

Subnet mask length for the network to announce(e.g, 8, 16, 24, etc.).

prefix

string / required

Network ID to announce via BGP.

route_map

string

Route map to modify the attributes.

router_id

string

Configures the BGP routing process router-id value.

operation

string

Specifies the operation to be performed on the BGP process configured on the device.

In case of merge, the input configuration will be merged with the existing BGP configuration on the device.

In case of replace, if there is a diff between the existing configuration and the input configuration, the existing configuration will be replaced by the input configuration for every option that has the diff.

In case of override, all the existing BGP configuration will be removed from the device and replaced with the input configuration.

In case of delete the existing BGP configuration will be removed from the device.

Choices:

  • merge ← (default)

  • replace

  • override

  • delete
