% gobgp neighbor 10.0.0.1 policy import add policy1 policy2 default acceptYou 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.

% gobgp policy prefix add ps1 10.33.0.0/16 16..24A PrefixSet it is possible to have multiple prefix, if you want to remove the PrefixSet to specify only PrefixSet name.
% gobgp policy prefix del ps1If you want to remove one element(prefix) of PrefixSet, to specify a prefix in addition to the PrefixSet name.
% gobgp policy prefix del ps1 10.33.0.0/16# add NeighborSet

% gobgp policy neighbor
# show a specific NeighborSet information
% gobgp policy neighbor <neighbor set name>If you want to add the NeighborSet:
% gobgp policy neighbor add ns1 10.0.0.1You can also specify a neighbor address range with the prefix representation:
% gobgp policy neighbor add ns 10.0.0.0/24A NeighborSet is possible to have multiple address, if you want to remove the NeighborSet to specify only NeighborSet name.
% gobgp policy neighbor del ns1If you want to remove one element(address) of NeighborSet, to specify a address in addition to the NeighborSet name.
% gobgp policy prefix del ns1 10.0.0.1# 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>If you want to add the AsPathSet:
% gobgp policy as-path add ass1 ^65100You can specify the position using regexp-like expression as follows:
- From:
^65100means 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_6500165100_[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.
% gobgp policy as-path del ass1If you want to remove one element(as path) of AsPathSet, to specify an as path in addition to the AsPathSet name.
% gobgp policy as-path del ass1 ^65100# add 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>If you want to add the CommunitySet:
% gobgp policy community add cs1 65100:10You 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.
% gobgp policy neighbor del cs1If you want to remove one element(community) of CommunitySet, to specify a address in addition to the CommunitySet name.
% gobgp policy prefix del cs1 65100:10# 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>If you want to add the ExtCommunitySet:
% gobgp policy ext-community add ecs1 RT:65100:10Extended community set as <SubType>:<Global Admin>:<LocalAdmin>.
If you read the RFC4360 and 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.
% gobgp policy neighbor del ecs1If you want to remove one element(extended community) of ExtCommunitySet, to specify a address in addition to the ExtCommunitySet name.
