Configure edge-safeguard and bpdu-restrict only on CIST for MSTP?

    Have an example MSTP configuration below.

    My questions is do I need to enable edge-safeguard and bpdu-restrict on each of the edge
    ports in all the STP domains or just the CIST (S0) as per below, and would this make any difference if the edge device was for example an IP phone and therefor be carrying vlans that are in two different MSTI's?

    configure mstp region Highgate
    configure stpd s0 delete vlan default ports all
    disable stpd s0 auto-bind vlan default
    disable stpd s0
    configure stpd s0 mode mstp cist
    create stpd s1
    configure stpd s1 mode mstp msti 1
    enable stpd s1 auto-bind vlan Unused1-MSTI1
    enable stpd s1 auto-bind vlan Unused2-MSTI1
    create stpd s2
    configure stpd s2 mode mstp msti 2
    enable stpd s2 auto-bind vlan Unused1-MSTI2
    enable stpd s2 auto-bind vlan Unused2-MSTI2
    configure stpd s0 ports link-type edge 1:1-47 edge-safeguard enable bpdu-restrict
    configure stpd s1 ports link-type edge 1:1-47 edge-safeguard enable bpdu-restrict
    configure stpd s2 ports link-type edge 1:1-47 edge-safeguard enable bpdu-restrict
    configure stpd s0 ports link-type point-to-point 1:48
    configure stpd s1 ports link-type point-to-point 1:48
    configure stpd s2 ports link-type point-to-point 1:48

    Many thanks in advance.
