Uplinks to the existing network may be configured as L2, L3 routed, or L3 VLAN. This section covers L3 routed uplinks.
Note: If L2 uplinks were configured in the preceding section, skip this section and go to Configure a jump host port.
Note: L3 VLAN uplink configuration is beyond the scope of this guide.
Connections, port numbers, and networks used for external management are shown in Figure 26. The External Management VLAN is VLAN 1711 on the external switches and is VLAN 1811 on the SmartFabric switches.
Figure 26. L3 routed uplinks to the external network
The point-to-point links used in this deployment are labeled A-E in Figure 27.
Figure 27. Point to Point connections
Each L3 uplink is a separate, point-to-point IP network. Table 6 details the links labeled in Figure 27. The IP addresses in the table are used in the switch configuration examples.
Table 6. L3 routed uplink IP addresses
Link label | Source switch | Source IP address | Destination switch | Destination IP address | Network |
A | External-A | 192.168.1.0 | Leaf1A | 192.168.1.1 | 192.168.1.0/31 |

This section covers the L3 routed uplink configuration with BGP.
Note: If BGP is not used, go to the Static route example.
Figure 28 shows the autonomous system numbers (ASNs) and router IDs used for the external switches and SFS leaf switches in this example. External switches share a common ASN, and all SFS leaf switches share a common ASN.
Figure 28. BGP ASNs and router IDs
Note: Using private ASNs in the data center is a best practice. Private, 2-byte ASNs range from 64512 through 65534.
In this example, ASN 65101 is used on both external switches. SFS leaf switches use ASN 65011 by default for all leafs in the fabric.
Note: If L3 uplinks are connected from SFS spine switches, the spine switches use ASN 65012 by default.
The IP addresses shown on the external network switches in Figure 28 are loopback addresses used as BGP router IDs. On the SmartFabric switches, BGP router IDs are automatically configured from the SFS default private subnet address block, 172.16.0.0/16.
Note: SFS default ASNs and IP address blocks may be changed by going to 5. Edit Default Fabric Settings in the SFS GUI.
Table 7 shows the values entered in the SFS GUI to configure the L3 uplinks for this example. The steps below the table are run once for each uplink using the values in the table.

Note: Any ports available on the leaf switches may be used as uplinks, provided they are compatible with the corresponding ports on the external switches. If leaf switch uplink ports will not use their native speeds, the interfaces must be first broken out to the correct speed before the uplinks are created. This is done using the 1. Breakout Switch Ports option on the SFS GUI home page. A breakout example is shown in the Change the port-group speed in the SFS GUI section of this guide.
To configure L3 routed uplinks with BGP, do the following using the data from Table 7:
Figure 29. SFS GUI Home Page
Figure 30. Uplink Details
Figure 31. Port Configuration
Figure 32. Network Configuration page with BGP
Repeat the steps in this section for the remaining three uplinks using the data from Table 7.
After uplink configuration, the SFS GUI Home page appears, as shown in Figure 33.
Figure 33. SFS Home page after uplinks configured
Individual uplinks created are visible on the Uplinks tab of the SFS GUI, as shown in Figure 34.
Figure 34. SFS L3 uplinks created
This section shows L3 routed uplink configuration with a static route.
Note: If BGP is used instead of a static route, continue to Configure external switches for L3 connections.
Note: Currently, only one static route per L3 uplink is allowed. If multiple routes are needed, use a default route, 0.0.0.0/0, as the destination network, or add additional uplinks for specific networks. Support for multiple static routes per L3 uplink is planned for a future release.
Table 8 shows the values entered in the SFS GUI to configure the L3 uplinks for this example. The steps below the table are run once for each uplink using the values from the table.

This section shows example configurations for both external switches for L3 routed connections to the SmartFabric.
Note: The external switches used in this example are Dell EMC PowerSwitch systems. If the external switches are Cisco Nexus, see Appendix C.
Note: This is only an example. Modify your external switch configuration as needed for your network.
Configure the hostname, OOB management IP address, and management route.
External-A | External-B |
configure terminal
hostname External-A
interface mgmt1/1/1 no ip address ip address 100.67.127.37/24 no shutdown

VLAN 1911 represents a preexisting management VLAN on the external network. DNS and NTP services are located on this VLAN. Assign a unique IP address to the VLAN on each switch.
Configure VRRP to provide gateway redundancy. Set the VRRP priority. The switch with the highest priority value becomes the master VRRP router. Assign the same virtual address to both switches.
External-A | External-B |
interface vlan1911 no shutdown ip address 172.19.11.252/24
vrrp-group 19 priority 150 virtual-address 172.19.11.254 | interface vlan1911 no shutdown ip address 172.19.11.253/24
vrrp-group 19 priority 100 virtual-address 172.19.11.254 |
Configure the interfaces for connections to the SFS switches. Ports 1/1/21 and 1/1/22 are configured as L3 interfaces. The IP addresses used are from Table 6. Optionally, allow the forwarding of jumbo frames with the MTU 9216 command. As a best practice, flow control settings remain at their factory defaults as shown.
In this example, VLT port channel 1 connects to the DNS/NTP server. It is on VLAN 1911, which represents the preexisting management VLAN, and the port channel is configured as a spanning tree edge port.
Interface 1/1/33 on each external switch is configured in VLT port channel 1 for connections to the DNS/NTP server. Port-channel 1 is set as an LACP port channel with the channel-group 1 mode active command.
External-A | External-B |
interface ethernet1/1/21 description Leaf1A no shutdown no switchport mtu 9216 ip address 192.168.1.0/31 flowcontrol receive on flowcontrol transmit off

interface port-channel1 description "To DNS/NTP" no shutdown switchport access vlan 1911 vlt-port-channel 1 spanning-tree port type edge
interface ethernet1/1/33 description "To DNS/NTP" no switchport channel-group 1 mode active no shutdown flowcontrol receive on flowcontrol transmit off |
This example uses interfaces 1/1/29 and 1/1/31 for the VLTi. Remove each interface from L2 mode with the no switchport command. As a best practice, flow control settings remain at their factory defaults, as shown.
Create the VLT domain. The backup destination is the OOB management IP address of the VLT peer switch. Configure the interfaces used as the VLTi with the discovery-interface command.
As a best practice, use the vlt-mac command to manually configure the same VLT MAC address on both the VLT peer switches. This improves VLT convergence time when a switch is reloaded.
Caution: Be sure the VLT MAC address is the same on both switches to avoid any unpredictable behavior.
If you do not configure a VLT MAC address, the MAC address of the primary peer is used as the VLT MAC address on both switches.
Note: For more information about VLT, see the Dell EMC SmartFabric OS10 User Guide on the Dell EMC Networking OS10 Info Hub.

Note: If BGP is not used, go to the Configure static routes section.
Configure a loopback interface to use for the BGP router ID.
Configure the BGP ASN with the router bgp command. The external switches share the same ASN. Use the address that was set for interface loopback0 as the router ID.
Use the address-family ipv4 unicast and redistribute connected commands to redistribute IPv4 routes from physically connected interfaces.
Configure the neighbor IP addresses and ASNs.
VLAN 4000 is used for the iBGP connection between the external switches. VLAN4000 IP addresses are configured per Table 6.
When the configuration is complete, exit configuration mode and save the configuration with the end and write memory commands.

Note: If BGP is used, skip this section and go to Validate BGP example.
Configure two routes to the external management network. This is 172.18.11.0/24, one to the connected IP address of Leaf1A, and one to Leaf1B.
When the configuration is complete, exit configuration mode and save the configuration with the end and write memory commands.

Note: This section shows validation commands for the BGP example. If static routes are used, skip this section and go to Validate static route example.
Now that the uplink interfaces are configured on the external switches and on the SFS leaf switches, connectivity can be verified using the switch CLI.
Note: The command output shown in the following commands is for the External-A switch. The output for External-B is similar.
Run the show ip bgp summary command to verify that BGP is up for each neighbor. When BGP is up, uptime is shown in the Up/Down column. The neighbors for External-A shown in the output below are Leaf1A, Leaf1B, and External-B.
