For MSD, isn't there a case where topology.switches won't exist in the host_vars as that's managed by child fabric vs MSD?

[ccoueffe]

I just update the existing, but I agree not sure we need this related to ISN in MSD.

Before:

when: >
    (MD_Extended.vxlan.fabric.type == 'ISN' and (MD_Extended.vxlan.topology.switches is defined and MD_Extended.vxlan.topology.switches | length > 0)) or
    MD_Extended.vxlan.fabric.type == 'MSD'

Update:

 when: >
      (MD_Extended.vxlan.fabric.type == 'ISN' and
       MD_Extended.vxlan.topology.switches is defined and
       MD_Extended.vxlan.topology.switches | length > 0)
      or
      (MD_Extended.vxlan.fabric.type == 'MSD' and
       MD_Extended.vxlan.topology.child_fabrics is defined and
       MD_Extended.vxlan.topology.child_fabrics | length > 0)

Expected:

 when: >
      (MD_Extended.vxlan.fabric.type == 'MSD' and
       MD_Extended.vxlan.topology.child_fabrics is defined and
       MD_Extended.vxlan.topology.child_fabrics | length > 0)
