Enabling the DvR-leaf-mode boot flag before you configure a node as a DvR Leaf, automatically removes all existing non-DvR configuration on the node such as platform VLANs and their IP address configuration, CLIP configuration, routing protocol configuration and VRF configuration. The gateway IPv4 address, if configured, is also removed.
You cannot configure SPB-PIM GW on a Leaf node. The configuration is supported only on a DvR Controller.
You cannot configure Microsoft NLB on a Leaf node.
You cannot configure Fabric Extend on a Leaf node.
You cannot configure the VXLAN Gateway on a Leaf node.
You cannot configure a T-UNI on a Leaf node.
You cannot configure IPv4 multicast on a Leaf node. The configuration is supported only on a DvR Controller.
You can configure only one instance of vIST on a Leaf node pair. Also, you cannot configure vIST on Leaf nodes from different domains.
You cannot configure platform VLANs on a Leaf node. Only configuration of SPBM B-VLANs is supported.
You cannot configure IP Shortcuts and IP Multicast over Fabric Connect on Leaf nodes. This configuration is pushed from the DvR Controllers in the domain.
You must manually configure an I-SID on a Layer 2 VSN, on the Leaf node. This configuration is not pushed from a DvR Controller.
DvR-enabled VLAN/ISIDs are for host connectivity only; you cannot connect a router to a DvR-enabled VLAN/ISID and use dynamic or static routing. Use a non-DvR VLAN/ISID instead to connect an external router.
