 Let’s assume a member would like to use BGP as number 65111 which is already in use by a different member.  In this case Deutsche Boerse will assign a free AS number to that member (in our example 65200) If the member is not willing to use the free AS number he has to use bgp local-as, no-prepend and replace-as.  Let’s assume a member would like to use BGP as number 65111 which is already in use by a different member.  In this case Deutsche Boerse will assign a free AS number to that member (in our example 65200) If the member is not willing to use the free AS number he has to use bgp local-as, no-prepend and replace-as.
