General purpose networks
General purpose networks are L2 VLAN networks in VxRail and L2 VXLAN networks in L3 fabric.
For L3 fabric, SmartFabric services automatically creates a virtual network corresponding to a network. This virtual network has
one-to-one mapping with the network, which means for each VLAN, there exists a virtual network with VNI same as the VLAN
ID.
VXLAN networks
VXLAN network extends L2 connectivity over an underlay L3 connected network.
Association of VXLAN network to interface creates a binding and associates this interface to VXLAN bridge.
You need to create a virtual network template and a network template, and associate the virtual network template to network
template.
● The virtual network template defines the VNET-id.
● Network template defines the VLAN ID.
In addition to whatever is specified in the L2 VXLAN network, for L3 VXLAN, specify:
● List of IP addresses. One IP address for each leaf.
● ANY-CAST IP address
L3 VXLAN network supports asymmetric-IRB.
L3 VLAN network
L3 VLAN network is used for L3 VLAN underlay.
Specify:
● VLAN ID
● Pair of IP addresses to be assigned to the VLT pair.
● VRRP gateway IP address for VIP
L3 Routed network
L3 Routed network is used to assign IP address on a single interface. Specify the IP address.
Attach this network to any uplink that has a single interface. This network can only be attached to a single entity.
Uplinks
An uplink is a set of ports that are connected to the customer network.
This uplink entity contains a rigid set of network characteristics.
Layer 2 Uplinks from leaf nodes
Layer 2 uplinks are a set of user-selected ports that belong to same VLT peer nodes on which the Layer 2 network is applied.
SFS creates a VLT LAG for these connected ports. If the ports are from a single device, then the VLT LAG is a single armed VLT
LAG. In case these ports exist on multiple nodes, a VLT or multi-chassis LAG is formed across these ports. This LAG can be
made as an access point for a VXLAN layer 2 network.
Layer 3 uplinks
Layer 3 uplinks can be configured on a leaf or a spine node.
Using Layer 3 VLAN network
Layer 3 VLAN network contains a list of IP addresses and a gateway IP address. Optionally, DHCP relay addresses can also be
specified. Layer 3 VLAN network can be configured over a leaf or a spine node. Layer 3 VLAN network can be attached to an
uplink. Each VLTi uplink interface contains an IP address that is allocated from the list of IP addresses that are configured on
the Layer 3 VLAN network.
Using Layer 3 routed network
Layer 3 routed network contains a list of IP addresses and a gateway IP address. Optionally, DHCP relay addresses can also be
specified. Layer 3 routed network can be configured on a leaf or a spine node. Layer 3 routed network can be attached to an
uplink. Each uplink interface contains an IP address that is allocated from the list of IP addresses that are configured on the
layer 3 routed network. An LACP port channel cannot be the remote end for these uplinks. If gateway IP is specified, then VRRP
is enabled and the switches configure this IP address as the gateway IP address.
