Appendix B. Sample custom interface template: multiple bonded interfaces The following template is a customized version of /usr/share/openstack-tripleo-heat-templates/network/config/bond-with-vlans/ceph-storage.yaml . It features multiple bonded interfaces to isolate back-end and front-end storage network traffic, along with redundancy for both connections. For more information, see Section 4.3, "Configuring multiple bonded interfaces for Ceph nodes" . It also uses custom bonding options, 'mode=4 lacp_rate=1' , see Section 4.3.1, "Configuring bonding module directives" . /usr/share/openstack-tripleo-heat-templates/network/config/bond-with-vlans/ceph-storage.yaml (custom)
