But the standby edge FIB table or the show ip forwarding command still shows the IP and is not removed from the FIB table.

After edge is disconnected and post HA failover, the disconnected edge interface IP address is removed from the active edge routing information base (RIB)/forwarding information base (FIB).

This vNIC is used by the dynamic routing protocol running on the DLR Control VM to communicate with the other routers to advertise and learn routes.

The point above holds true until a dynamic routing protocol is configured on the DLR, when the IP address will be removed along with the ARP filter and replaced with the “Protocol IP” address specified during the dynamic routing protocol configuration.

There is an ARP filter applied for this vNIC’s MAC address that makes it happen.

Note that the IP address seen on this interface is the same as the DLR’s LIF however, the DLR Control VM will not answer ARP queries for the LIF IP address (in this case, 192.168.10.2/29).

Interface vNic_2 is an Uplink type therefore, it is represented as a “real” vNIC.

Having the “Internal” type is a requirement, or HA will fail.

On an ESG, the operator can manually assign one of its vNICs as HA, or leave it as default for the system to choose automatically from available “Internal” interfaces.

This appears as two IP addresses, 169.254.1.1/30 (auto-assigned for HA), and 10.10.10.1/24, manually assigned to the HA interface.

The output above was taken from a DLR deployed with HA enabled, and the HA interface is assigned an IP address.Interface vNic_0 in this example is the HA interface.

It is a single “pseudo-interface” that is configured with all IP addresses for all DLR’s “Internal” LIFs. Interface “VDR” does not have a VM NIC (vNIC) associated with it.Interface vNic_2 is up, line protocol is up Input packets 582249, bytes 37339072, dropped 49, multicast packets 0 Interface vNic_0 is up, line protocol is up Output errors 0, aborted 0, carrier 0, fifo 0, heartbeat 0, window 0 Input errors 0, length 0, overrun 0, CRC 0, frame 0, fifo 0, missed 0 Input packets 0, bytes 0, dropped 0, multicast packets 0 The DLR Control VM’s interfaces can be displayed as follows:Īuto-duplex (Full), Auto-speed (2460Mb/s) The “VDR” interface is a pseudo-interface that does not correspond to a vNIC. The “VDR” interface is displayed for all LIFs of “Internal” type.The purpose of the Forwarding Table is to show which DLR interface is chosen as the egress for a given destination subnet.The major output of DLR Control VM’s lifecycle is the DLR routing table, which is a product of Interfaces and Routes.Ĭodes: O - OSPF derived, i - IS-IS derived, B - BGP derived,Ĭ - connected, S - static, L1 - IS-IS level-1, L2 - IS-IS level-2, Note that unlike on the ESXi hosts, this table does not include any directly connected subnets because this information is provided by the LIF configuration.ĭLR Control VM has LIFs and routing/forwarding tables. The “routes” shows the routing table sent to this Controller by this DLR’s Control VM.The “interface-summary” displays the LIFs that the Controller learned from the NSX Manager.In a correctly functioning environment, this list would include all hosts from all clusters where the DLR exists. The “instance” sub-command of the “show control-cluster logical-routers” command displays list of hosts that are connected to this Controller for this DLR Instance.Nsx-controller # show control-cluster logical-routers routes 1460487509 Nsx-controller # show control-cluster logical-routers instance 1460487509
