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. Using Layer 3 VXLAN network Layer 3 VXLAN network is a VXLAN type of network that contains a list of IP addresses and an anycast IP address. Optionally, DHCP relay addresses can also be specified. Layer 3 VXLAN network can be configured over a leaf node. Layer 3 VXLAN 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 VXLAN network. Static routing policies A static route is a route policy template that contains a network prefix and the next hop IP address. This policy can be attached to one or more nodes in the fabric. When this policy is attached to the node, a static route with the specified prefix and next hop IP address is configured in the node. eBGP peering policies An eBGP peering policy is a routing policy template that contains BGP remote addresses and the remote AS number. A remote address can be an interface address or a loopback address. This policy can be attached to one or more nodes in a fabric. When this policy is attached to the node, a BGP session is associated with the switch. Uplink bonding options Following are the options using which uplink bonding can be achieved: • LACP • Static bonding • No bonding type configured • Spanningtree considerations LACP In LACP uplink bonding, SmartFabric services wait for LACP PDUs from the remote device to configure the LACP LAG for the uplink. Networks that are attached to the uplink are associated with the LACP LAG that is created. Static bonding In static bonding, SmartFabric services configure a static LAG for the uplink and the networks that are attached on the uplink are associated with the LAG that is created. No bonding type configured When no bonding type is configured, network is attached to the uplink physical interface. This configuration is used specifically by layer 3 routed uplinks. 112 SmartFabric Services
