Do Not Advertise Communities to Neighbors

By default, communities are sent to BGP peers. To suppress the advertisement of communities to a neighbor, remove all communities. When the result of an export policy is an empty set of communities, the community attribute is not sent. To remove all communities, first define a wildcard set of communities (here, the community is named wild):



[edit policy-options]
community wild members "* : *";

Then, in the routing policy statement, specify the community delete action:



[edit policy-options]

policy-statement policy-name {


term term-name {
then community delete wild;
}


}

To suppress a particular community from any AS, define the community as community wild members "*:community-value".
