Configuration This Module augments the "/rt:routing/rt:routing-instance:" with a BIER container. This Container defines all the configuration parameters related to BIER for this particular routing-instance. The BIER configuration contains global routing-instance configuration and interface configuration. The global routing-instance configuration includes BIER transport type, AF, MT. The interface configuration includes name and bfd. 4. Control plane configuration This Module augments routing-protocol configuration with BIER. This Module supports ISIS ([I-D.ietf-bier-isis-extensions])and OSPF ([I-D.ietf-bier-ospf-bier-extensions]) as control plane for BIER. 5. States It proposes mt-id, subdomain and other information, such as bier- mapping-information. Chen, et al. Expires January 7, 2016 [Page 4] Internet-Draft BIER YANG July 2015 6. Notification This Module includes bfr-id-collision, bfr-zero, sub-domain-id- collision. 7.
