If you are using two different IP addresses for the DvR VLAN and the DvR GW IP, you must first configure a gateway IPv4 address and then configure an IP interface for the VLAN before you enable DvR on a Layer 2 VSN (VLAN). Both the VLAN IP address and the gateway IPv4 address must be in the same subnet.
If you use same IP address for VLAN interface and DvR GW IP, you can use the command ip address {A.B.C.D/X} dvr-one-ip.
For more information, see Enable DvR on a Layer 2 VSN (VLAN) and Configure a Single IP Address for All DvR Controllers on a VLAN Subnet.
You cannot configure IPv4 VRRP on a DvR-enabled VLAN.
You cannot configure RSMLT on a DvR-enabled VLAN.
You cannot configure SPB-PIM Gateway (SPB-PIM GW) on a DvR VLAN.
You cannot configure dynamic routing protocols, such as OSPF, RIP, BGP, IPv6 OSPFv3, IPv6 RIPng, IPv6 MLD, and IPv6 PIM-GW on a DvR-enabled VLAN.
You can configure DvR on a VLAN that has configured IPv6 interface. You must first delete the IPv6 interface, configure DvR, and then reconfigure IPv6 interface.
A DvR VLAN is a VLAN configured on a DvR Controller with a VLAN IP address, a VLAN/I-SID, the DvR gateway IP address, and DvR enabled. This Layer 3 configuration for the DvR VLAN (the DvR gateway IP address and this DvR subnet) is pushed to the DvR Leaf nodes. The DvR gateway IP address must be the same address across all DvR Controllers for that DvR VLAN.
You cannot configure an IPv6 interface on a DvR-enabled VLAN from a subnet that is used as next-hop in a IPv6 static route.
You cannot configure an IPv6 address on a DvR-enabled VLAN from a subnet used as an IPv6 BGP Peer.
DvR-enabled VLAN/I-SIDs are for host connectivity only; you cannot connect a router to a DvR-enabled VLAN/I-SID and use dynamic or static routing. Use a non-DvR VLAN/I-SID instead to connect an external router.
