Here is some sample output for LLDP: cumulus@leaf1:~$ sudo lldpctl ------------------------------------------------------------------------------- LLDP neighbors: ------------------------------------------------------------------------------- Interface: swp49, via: LLDP, RID: 3, Time: 28 days, 19:33:36 Chassis: ChassisID: mac 6c:64:1a:00:51:1e SysName: spine01 SysDescr: Cumulus Linux MgmtIP: 10.2.1.3 Capability: Bridge, off Capability: Router, on Port: PortID: ifname swp1 PortDescr: swp1 ------------------------------------------------------------------------------- Interface: swp50, via: LLDP, RID: 2, Time: 28 days, 19:33:36 Chassis: ChassisID: mac 6c:64:1a:00:4f:9b SysName: spine02 SysDescr: Cumulus Linux MgmtIP: 10.2.1.4 Capability: Bridge, off Capability: Router, on Port: PortID: ifname swp1 PortDescr: swp1 ------------------------------------------------------------------------------- To verify that OSPF is up and running correctly, run cl-ospf neighbor: cumulus@leaf1:~$ sudo cl-ospf neighbor Neighbor ID Pri State Dead Time Address Interface 10.2.1.3 1 Full/DROther 33.787s 10.2.1.3 swp49:10.2.1.1 10.2.1.4 1 Full/DROther 33.788s 10.2.1.4 swp50:10.2.1.1 7. Connect Network Fabric You can now connect up your Hadoop network to your core network.
