More Information
Summary:Described herein are systems and methods that provide for auto-discovery of VXLAN tunnel endpoints (VTEPs) using a protocol-independent multicast (PIM) bootstrap router (BSR). In one or more embodiments, a node may be configured via PIM messaging in which nodes of a network provide their candidate-rendezvous point (RP) advertisements send their information of candidate-RP to multicast group information to an elected BSR. The elected BSR consolidates the candidate-RP to multicast group information and propagates this information to nodes through PIM messages to all PIM routers in the network. In one or more embodiments, a node uses this information in combination with its local configuration mapping of VNIDs-to-multicast-group information to generate a remote VTEP-IP-(RP)-to-VNID mapping, which can be used to auto configure the node's VXLAN with remote-VTEP and VNI profiles in static VXLAN deployments.
