# CLI command syntax

This page explains gobgp client command syntax.



## basic command pattern
gobgp \<subcommand> \<object>  opts...

gobgp has six subcommands.
- [global](#global)
- [neighbor](#neighbor)
- [policy](#policy)
- [vrf](#vrf)
- [monitor](#monitor)
- [mrt](#mrt)


## 1. <a name="global"> global subcommand
### 1.1. 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>]
# show all Route information
% gobgp global rib [-a <address family>]
# show a specific route information
% gobgp global rib [<prefix>|<host>] [longer-prefix] [-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
```

#### - option
The following options can be specified in the global subcommand:

| short  |long           | description                                |
|--------|---------------|--------------------------------------------|
|a       |address-family |specify the ipv4, ipv6, evpn, encap, or rtc |

<br>

## 2. <a name="neighbor"> neighbor subcommand
### 2.1. Show Neighbor Status
#### - syntax
```shell
# show neighbor's status as list
% gobgp neighbor
# show status of a specific neighbor
% gobgp neighbor <neighbor address>
```

### 2.2. Operations for neighbor - shutdown/reset/softreset/enable/disable -
#### - syntax
```shell
% gobgp neighbor <neighbor address> shutdown
% gobgp neighbor <neighbor address> reset
% gobgp neighbor <neighbor address> softreset [-a <address family>]
% gobgp neighbor <neighbor address> softresetin [-a <address family>]
% gobgp neighbor <neighbor address> softresetout [-a <address family>]
% gobgp neighbor <neighbor address> enable
% gobgp neighbor <neighbor address> disable
```
#### - option
  The following options can be specified in the neighbor subcommand:

| short  |long           | description                  |
|--------|---------------|------------------------------|
|a       |address-family |specify the ipv4 or ipv6      |


### 2.3. Show Rib - local-rib/adj-rib-in/adj-rib-out -
#### - syntax
```shell
# show all routes in [local|adj-in|adj-out] table
% gobgp neighbor <neighbor address> [local|adj-in|adj-out] [-a <address family>]
# show a specific route in [local|adj-in|adj-out] table
% gobgp neighbor <neighbor address> [local|adj-in|adj-out] [<prefix>|<host>] [longer-prefix] [-a <address family>]
```

#### - example
If you want to show the local rib of ipv4 that neighbor(10.0.0.1) has：
```shell
% gobgp neighbor 10.0.0.1 local -a ipv4
```

#### - option
The following options can be specified in the neighbor subcommand:

| short  |long           | description                  |
|--------|---------------|------------------------------|
|a       |address-family |specify the ipv4 or ipv6      |


### 2.4. Operations for Policy  - add/del/show -
#### Syntax
```shell
# show neighbor policy assignment
% gobgp neighbor <neighbor address> policy { in | import | export }
# add policies to specific neighbor policy
% gobgp neighbor <neighbor address> policy { in | import | export } add <policy name>... [default { accept | reject }]
# set policies to specific neighbor policy
% gobgp neighbor <neighbor address> policy { in | import | export } set <policy name>... [default { accept | reject }]
# remove attached policies from specific neighbor policy
% gobgp neighbor <neighbor address> policy { in | import | export } del <policy name>...
# remove all policies from specific neighbor policy
% gobgp neighbor <neighbor address> policy { in | import | export } del
```

#### 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.


<br>

## 3. <a name="policy"> 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>
# 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
```
A NeighborSet it 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
```
