     1  # CLI command syntax
     2  
     3  This page explains gobgp client command syntax.
     4  
     5  ## basic command pattern
     6  
     7  ```shell
     8  gobgp <subcommand> <object> opts...
     9  ```
    10  
    11  gobgp has the following subcommands.
    12  
    13  - [global](#1-global-subcommand)
    14  - [neighbor](#2-neighbor-subcommand)
    15  - [policy](#3-policy-subcommand)
    16  - [vrf](#4-vrf-subcommand)
    17  - [monitor](#5-monitor-subcommand)
    18  - [mrt](#6-mrt-subcommand)

    22  ### 1.1 Global Configuration
    23  
    24  #### syntax
    25  
    26  ```shell
    27  # configure global setting and start acting as bgp daemon
    28  % gobgp global as <VALUE> router-id <VALUE> [listen-port <VALUE>] [listen-addresses <VALUE>...] [mpls-label-min <VALUE>] [mpls-label-max <VALUE>]
    29  # delete global setting and stop acting as bgp daemon (all peer sessions will be closed)
    30  % gobgp global del all
    31  # show global setting
    32  % gobgp global
    33  ```
    34

    39  ```shell
    40  # add Route
    41  % gobgp global rib add <prefix> [-a <address family>]
    42  # delete a specific Route
    43  % gobgp global rib del <prefix> [-a <address family>]
    44  # delete all locally generated routes
    45  % gobgp global rib del all [-a <address family>]
    46  # show all Route information

   225  ```
   226  
   227  #### Example
   228  
   229  If you want to add the PrefixSet:
   230  
   231  ```shell
   232  % gobgp policy prefix add ps1 10.33.0.0/16 16..24
   233  ```
   234  
   235  A PrefixSet it is possible to have multiple prefix, if you want to remove the PrefixSet to specify only PrefixSet name.
   236  
   237  ```shell
   238  % gobgp policy prefix del ps1
   239  ```
   240  
   241  If you want to remove one element(prefix) of PrefixSet, to specify a prefix in addition to the PrefixSet name.
   242

   245  ```
   246  
   247  ### 3.2. Operations for NeighborSet - add/del/show -
   248  
   249  #### Syntax
   250  
   251  ```shell

   253  % gobgp policy neighbor add <neighbor set name> <neighbor address/prefix>
   254  # delete a NeighborSet
   255  % gobgp policy neighbor del <neighbor set name>
   256  # delete a neighbor from a NeighborSet
   257  % gobgp policy neighbor del <neighbor set name> <address>
   258  # show all NeighborSet information
   259  % gobgp policy neighbor
   260  # show a specific NeighborSet information
   261  % gobgp policy neighbor <neighbor set name>
   262  ```
   263  
   264  #### Example
   265  
   266  If you want to add the NeighborSet:
   267  
   268  ```shell
   269  % gobgp policy neighbor add ns1 10.0.0.1
   270  ```
   271  
   272  You can also specify a neighbor address range with the prefix representation:
   273  
   274  ```shell
   275  % gobgp policy neighbor add ns 10.0.0.0/24
   276  ```
   277  
   278  A NeighborSet is possible to have multiple address, if you want to remove the NeighborSet to specify only NeighborSet name.
   279  
   280  ```shell
   281  % gobgp policy neighbor del ns1
   282  ```
   283  
   284  If you want to remove one element(address) of NeighborSet, to specify a address in addition to the NeighborSet name.
   285

   288  ```
   289  
   290  ### 3.3. Operations for AsPathSet - add/del/show -
   291  
   292  #### Syntax
   293  
   294  ```shell
   295  # add AsPathSet
   296  % gobgp policy as-path add <aspath set name> <as path>
   297  # delete a specific AsPathSet
   298  % gobgp policy as-path del <aspath set name>
   299  # delete an as-path from a AsPathSet
   300  % gobgp policy as-path del <aspath set name> <as path>
   301  # show all AsPathSet information
   302  % gobgp policy as-path
   303  # show a specific AsPathSet information
   304  % gobgp policy as-path <aspath set name>

   307  #### Example
   308  
   309  If you want to add the AsPathSet:
   310  
   311  ```shell
   312  % gobgp policy as-path add ass1 ^65100
   313  ```
   314  
   315  You can specify the position using regexp-like expression as follows:
   316  
   317  - From: `^65100` means the route is passed from AS 65100 directly.
   318  - Any: `_65100_` means the route comes through AS 65100.
   319  - Origin: `_65100$` means the route is originated by AS 65100.
   320  - Only: `^65100$` means the route is originated by AS 65100 and comes from it directly.
   321  
   322  Further you can specify the consecutive aspath and use regexp in each element as follows:
   323  
   324  - `^65100_65001`
   325  - `65100_[0-9]+_.*$`
   326  - `^6[0-9]_5.*_65.?00$`
   327  
   328  An AsPathSet it is possible to have multiple as path, if you want to remove the AsPathSet to specify only AsPathSet name.
   329  
   330  ```shell
   331  % gobgp policy as-path del ass1
   332  ```
   333  
   334  If you want to remove one element(as path) of AsPathSet, to specify an as path in addition to the AsPathSet name.
   335  
   336  ```shell
   337  % gobgp policy as-path del ass1 ^65100
   338  ```
   339  
   340  ### 3.4. Operations for CommunitySet - add/del/show -
   341  
   342  #### Syntax
   343  
   344  ```shell

   346  % gobgp policy community add <community set name> <community>
   347  # delete a specific CommunitySet
   348  % gobgp policy community del <community set name>
   349  # delete a community from a CommunitySet
   350  % gobgp policy community del <community set name> <community>
   351  # show all CommunitySet information
   352  % gobgp policy community
   353  # show a specific CommunitySet information
   354  % gobgp policy community <community set name>
   355  ```
   356  
   357  #### Example
   358  
   359  If you want to add the CommunitySet:
   360  
   361  ```shell
   362  % gobgp policy community add cs1 65100:10
   363  ```
   364  
   365  You can specify the position using regexp-like expression as follows:
   366  
   367  - `6[0-9]+:[0-9]+`
   368  - `^[0-9]*:300$`
   369  
   370  A CommunitySet it is possible to have multiple community, if you want to remove the CommunitySet to specify only CommunitySet name.
   371  
   372  ```shell
   373  % gobgp policy neighbor del cs1
   374  ```
   375  
   376  If you want to remove one element(community) of CommunitySet, to specify a address in addition to the CommunitySet name.
   377  
   378  ```shell
   379  % gobgp policy prefix del cs1 65100:10
   380  ```
   381  
   382  ### 3.5. Operations for ExtCommunitySet - add/del/show -
   383  
   384  #### Syntax
   385  
   386  ```shell
   387  # add ExtCommunitySet
   388  % gobgp policy ext-community add <extended community set name> <extended community>
   389  # delete a specific ExtCommunitySet
   390  % gobgp policy ext-community del <extended community set name>
   391  # delete a ext-community from a ExtCommunitySet
   392  % gobgp policy ext-community del <extended community set name> <extended community>
   393  # show all ExtCommunitySet information
   394  % gobgp policy ext-community
   395  # show a specific ExtCommunitySet information
   396  % gobgp policy ext-community <extended community set name>
   397  ```
   398  
   399  #### Example
   400  
   401  If you want to add the ExtCommunitySet:
   402  
   403  ```shell
   404  % gobgp policy ext-community add ecs1 RT:65100:10
   405  ```
   406  
   407  Extended community set as `<SubType>:<Global Admin>:<LocalAdmin>`.
   408  
   409  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.
   410  
   411  You can specify the position using regexp-like expression as follows:
   412  
   413  - `RT:[0-9]+:[0-9]+`
   414  - `SoO:10.0.10.10:[0-9]+`
   415  
   416  However, regular expressions for subtype can not be used, to use for the global admin and local admin.
   417  
   418  A ExtCommunitySet it is possible to have multiple extended community, if you want to remove the ExtCommunitySet to specify only ExtCommunitySet name.
   419
