The 90:b1:1c:f4:29:f3 MAC address belongs to Dell-2.Also note that these MAC addresses are marked with LOCAL_DA. This means, these are the local destination MAC addresses used byhosts when routing is required. Packets sent to this MAC address are directly forwarded to their destinations without being sent to thepeer switch.Dell-2 Switch ConfigurationIn the following output, RSTP is enabled with a bridge priority of 32768, which is the second lowest in this topology. This ensures thatDell-2 becomes the root bridge if Dell-1 fails.Dell#2#sh run | find protocolprotocol spanning-tree pvstno disablevlan 1,20,800,900 bridge-priority 32768The following output shows the existing VLANs.Dell#1#show vlan | find NUMNUM Status Description Q Ports* 1 Active U Po10 (Te 0/0-1)20 Active OSPF PEERING VLAN U Po1 (Te 0/6)V Po10 (Te 0/0-1)800 Active Client-VLAN V Po10 (Te 0/0-1)U Te 0/4900 Active Client-VLAN-2 V Po10 (Te 0/0-1)Configuration on InterfacesDell#2#sh run int ma0/0interface ManagementEthernet 0/0description Used_for_VLT_Keepaliveip address 10.10.10.2/24no shutdownIn Dell-2, te 0/0 and te 0/1 are used for VLTi.Dell#2#sh run int te0/0interface TenGigabitEthernet 0/0description VLTi LINKno ip addressno shutdown!Dell#1#sh run int te0/1interface TenGigabitEthernet 0/1description VLTi LINKno ip addressno shutdownVirtual Link Trunking (VLT) 953
