Configuring the SoO attribute
After you configure the SoO attribute for a BGP peer or peer group, BGP adds the SoO attribute into the
route updates received from the BGP peer or peer group. In addition, before advertising route updates
to the peer or peer group, BGP checks the SoO attribute of the route update against the configured SoO
attribute. If they are the same, BGP does not advertise the route updates to the BGP peer or peer group.
