SFS uplink options to external network switches include:
The L2 uplink may be an LACP or static LAG. If L2 uplinks connect to a pair of Dell PowerSwitch systems, Dell Technologies recommends using LACP with VLT per the example in this guide.
L2 uplink configuration is covered in detail in Configure L2 uplinks to the external switches.
Note: With L2 uplinks, all routing into and out of the SmartFabric is done on external switches.
SFS supports using L3 routed or L3 VLAN uplinks.
With L3 routed uplinks, each physical link is a point-to-point IP network. With L3 VLAN, all uplinks are in a LAG, and an IP address is assigned to the VLAN containing the LAG.
SmartFabric supports routing using eBGP or static routes. SFS does not support other routing protocols.
