    Hi everyone,

    I noticed when we use APSTRA to build EBGP underlay network for VXLAN, it announces underlay leaf's   underlay loopback ip with community :DEFAULT_DIRECT_V4

    Which is defined on all leafs by APSTRA:

    set policy-options community DEFAULT_DIRECT_V4 members 1:20007
    set policy-options community DEFAULT_DIRECT_V4 members 21001:26000

    1) I observed none of the leafs and spines have BGP import policy, if there is no import policy referencing community DEFAULT_DIRECT_V4  to perform any action. then what is the point announcing routes with this community?

    Thanks and have a good day!!
