is_bfd_block
-

Choices:
- no_use ←
- true
- false

If the value is true, peers are enabled to inherit the BFD function from the peer group. If the value is false, peers are disabled to inherit the BFD function from the peer group.

is_bfd_enable
-

Choices:
- no_use ←
- true
- false

If the value is true, BFD is enabled. If the value is false, BFD is disabled.

is_ignore
-

Choices:
- no_use ←

- false

If the value is true, the session with a specified peer is torn down and all related routing entries are cleared. If the value is false, the session with a specified peer is retained.

is_log_change
-

Choices:
- no_use ←
- true
- false

If the value is true, BGP is enabled to record peer session status and event information. If the value is false, BGP is disabled from recording peer session status and event information.

is_single_hop
-

Choices:
- no_use ←
- true
- false

If the value is true, the system is enabled to preferentially use the single-hop mode for BFD session setup between IBGP peers. If the value is false, the system is disabled from preferentially using the single-hop mode for BFD session setup between IBGP peers.

key_chain_name - |  | Specify the Keychain authentication name used when BGP peers establish a TCP connection. The value is a string of 1 to 47 case-insensitive characters.
local_if_name - |  | Name of a source interface that sends BGP packets. The value is a string of 1 to 63 characters.
min_hold_time - |  | Specify the Min hold time of a peer or peer group.

mpls_local_ifnet_disable
-

Choices:
- no_use ←
- true
- false

If the value is true, peer create MPLS Local IFNET disable. If the value is false, peer create MPLS Local IFNET enable.

multiplier - |  | Specify the detection multiplier. The default value is 3. The value is an integer ranging from 3 to 50.
peer_addr - / required |  | Connection address of a peer, which can be an IPv4 or IPv6 address.

prepend_fake_as
-

Choices:
- no_use ←
- true
- false

prepend_global_as
-

Choices:
- no_use ←
- true
- false

Add the global AS number to the Update packets to be advertised.

pswd_type
-

Choices:
- null
- cipher
- simple

Enable BGP peers to establish a TCP connection and perform the Message Digest 5 (MD5) authentication for BGP messages.

remote_as - / required |  | AS number of a peer. The value is a string of 1 to 11 characters.

route_refresh
-

Choices:
- no_use ←
- true
- false

If the value is true, BGP is enabled to advertise REFRESH packets. If the value is false, the route refresh function is enabled.

## Notes

Note

- This module requires the netconf system service be enabled on the remote device being managed.

- Recommended connection is `netconf`.

- This module also works with `local` connections for legacy playbooks.

## Examples
