# CLI command syntax

This page explains gobgp client command syntax.

## basic command pattern

```shell
gobgp <subcommand> <object> opts...
```

gobgp has the following subcommands.

- [global](#1-global-subcommand)
- [neighbor](#2-neighbor-subcommand)
- [policy](#3-policy-subcommand)
- [vrf](#4-vrf-subcommand)
- [monitor](#5-monitor-subcommand)
- [mrt](#6-mrt-subcommand)

## 1. global subcommand

### 1.1 Global Configuration

#### syntax

```shell
# configure global setting and start acting as bgp daemon
% gobgp global as <VALUE> router-id <VALUE> [listen-port <VALUE>] [listen-addresses <VALUE>...] [mpls-label-min <VALUE>] [mpls-label-max <VALUE>]
# delete global setting and stop acting as bgp daemon (all peer sessions will be closed)
% gobgp global del all
# show global setting
% gobgp global
```

### 1.2. Operations for Global-Rib - add/del/show -

#### - syntax

```shell
# add Route
% gobgp global rib add <prefix> [-a <address family>]
# delete a specific Route
% gobgp global rib del <prefix> [-a <address family>]
# delete all locally generated routes
% gobgp global rib del all [-a <address family>]
# show all Route information
% gobgp global rib [-a <address family>]
# show a specific route information
% gobgp global rib [<prefix>|<host>] [longer-prefixes|shorter-prefixes] [-a <address family>]
# show table summary
% gobgp global rib summary [-a <address family>]
```

#### - example

If you want to add routes with the address of the ipv4 to global rib:

```shell
% gobgp global rib add 10.33.0.0/16 -a ipv4
```

If you want to remove routes with the address of the ipv6 from global rib:

```shell
% gobgp global rib del 2001:123:123:1::/64 -a ipv6
```

```

#### Example

If you want to add the import policy to neighbor(10.0.0.1):

```shell
% gobgp neighbor 10.0.0.1 policy import add policy1 policy2 default accept
```

You can specify multiple policy to neighbor separated by commas.

`default <policy action>` means the operation `{accept | reject}` in the case where the route does not match the conditions of the policy.

## 3. policy subcommand

### 3.1. Operations for PrefixSet - add/del/show -

#### Syntax

```shell
# add PrefixSet
% gobgp policy prefix add <prefix set name> <prefix> [<mask length range>]
# delete a PrefixSet
% gobgp policy prefix del <prefix set name>
# delete a prefix from specific PrefixSet
% gobgp policy prefix del <prefix set name> <prefix> [<mask length range>]
# show all PrefixSet information
% gobgp policy prefix
# show a specific PrefixSet
% gobgp policy prefix <prefix set name>
```

#### Example

If you want to add the PrefixSet:

```shell
% gobgp policy prefix add ps1 10.33.0.0/16 16..24
```

A PrefixSet it is possible to have multiple prefix, if you want to remove the PrefixSet to specify only PrefixSet name.

```shell
% gobgp policy prefix del ps1
```

If you want to remove one element(prefix) of PrefixSet, to specify a prefix in addition to the PrefixSet name.

```shell
% gobgp policy prefix del ps1 10.33.0.0/16
```

### 3.2. Operations for NeighborSet - add/del/show -

#### Syntax

```shell
# add NeighborSet
% gobgp policy neighbor add <neighbor set name> <neighbor address/prefix>
# delete a NeighborSet
% gobgp policy neighbor del <neighbor set name>
# delete a neighbor from a NeighborSet
% gobgp policy neighbor del <neighbor set name> <address>
# show all NeighborSet information
% gobgp policy neighbor
# show a specific NeighborSet information
% gobgp policy neighbor <neighbor set name>
```

#### Example

If you want to add the NeighborSet:

```shell
% gobgp policy neighbor add ns1 10.0.0.1
```

You can also specify a neighbor address range with the prefix representation:

```shell
% gobgp policy neighbor add ns 10.0.0.0/24
```

A NeighborSet is possible to have multiple address, if you want to remove the NeighborSet to specify only NeighborSet name.

```shell
% gobgp policy neighbor del ns1
```

If you want to remove one element(address) of NeighborSet, to specify a address in addition to the NeighborSet name.

```shell
% gobgp policy prefix del ns1 10.0.0.1
```

### 3.3. Operations for AsPathSet - add/del/show -

#### Syntax

```shell
# add AsPathSet
% gobgp policy as-path add <aspath set name> <as path>
# delete a specific AsPathSet
% gobgp policy as-path del <aspath set name>
# delete an as-path from a AsPathSet
% gobgp policy as-path del <aspath set name> <as path>
# show all AsPathSet information
% gobgp policy as-path
# show a specific AsPathSet information
% gobgp policy as-path <aspath set name>
```

#### Example

If you want to add the AsPathSet:

```shell
% gobgp policy as-path add ass1 ^65100
```

You can specify the position using regexp-like expression as follows:

- From: `^65100` means the route is passed from AS 65100 directly.
- Any: `_65100_` means the route comes through AS 65100.
- Origin: `_65100$` means the route is originated by AS 65100.
- Only: `^65100$` means the route is originated by AS 65100 and comes from it directly.

Further you can specify the consecutive aspath and use regexp in each element as follows:

- `^65100_65001`
- `65100_[0-9]+_.*$`
- `^6[0-9]_5.*_65.?00$`

An AsPathSet it is possible to have multiple as path, if you want to remove the AsPathSet to specify only AsPathSet name.

```shell
% gobgp policy as-path del ass1
```

If you want to remove one element(as path) of AsPathSet, to specify an as path in addition to the AsPathSet name.

```shell
% gobgp policy as-path del ass1 ^65100
```

### 3.4. Operations for CommunitySet - add/del/show -

#### Syntax

```shell
# add CommunitySet
% gobgp policy community add <community set name> <community>
# delete a specific CommunitySet
% gobgp policy community del <community set name>
# delete a community from a CommunitySet
% gobgp policy community del <community set name> <community>
# show all CommunitySet information
% gobgp policy community
# show a specific CommunitySet information
% gobgp policy community <community set name>
```

#### Example

If you want to add the CommunitySet:

```shell
% gobgp policy community add cs1 65100:10
```

You can specify the position using regexp-like expression as follows:

- `6[0-9]+:[0-9]+`
- `^[0-9]*:300$`

A CommunitySet it is possible to have multiple community, if you want to remove the CommunitySet to specify only CommunitySet name.

```shell
% gobgp policy neighbor del cs1
```

If you want to remove one element(community) of CommunitySet, to specify a address in addition to the CommunitySet name.

```shell
% gobgp policy prefix del cs1 65100:10
```

### 3.5. Operations for ExtCommunitySet - add/del/show -

#### Syntax

```shell
# add ExtCommunitySet
% gobgp policy ext-community add <extended community set name> <extended community>
# delete a specific ExtCommunitySet
% gobgp policy ext-community del <extended community set name>
# delete a ext-community from a ExtCommunitySet
% gobgp policy ext-community del <extended community set name> <extended community>
# show all ExtCommunitySet information
% gobgp policy ext-community
# show a specific ExtCommunitySet information
% gobgp policy ext-community <extended community set name>
```

#### Example

If you want to add the ExtCommunitySet:

```shell
% gobgp policy ext-community add ecs1 RT:65100:10
```

Extended community set as `<SubType>:<Global Admin>:<LocalAdmin>`.

If you read the [RFC4360](https://tools.ietf.org/html/rfc4360) and [RFC7153](https://tools.ietf.org/html/rfc7153), you can know more about Extended community.

You can specify the position using regexp-like expression as follows:

- `RT:[0-9]+:[0-9]+`
- `SoO:10.0.10.10:[0-9]+`

However, regular expressions for subtype can not be used, to use for the global admin and local admin.

A ExtCommunitySet it is possible to have multiple extended community, if you want to remove the ExtCommunitySet to specify only ExtCommunitySet name.

```shell
% gobgp policy neighbor del ecs1
```

If you want to remove one element(extended community) of ExtCommunitySet, to specify a address in addition to the ExtCommunitySet name.

```shell
% gobgp policy prefix del ecs1 RT:65100:10
```

% gobgp policy large-community del <set name> <large community>
# show all LargeCommunitySet information
% gobgp policy large-community

% gobgp policy large-community add l0 :100$
% gobgp policy large-community del l0 100:100:100
% gobgp policy large-community add l0 200:100:100
