Initial Configuration Create 4 VLANs, 10,20,30,40 Trunk between the 3 Switches or you can follow the configuration from previous lab for the 3 Switches click here create SVI for VLAN 10 on CORE1 and CORE2 CORE1(config)#int vlan 10 CORE1(config-if)#ip add 10.10.10.1 255.255.255.0 CORE1(config-if)#no shut CORE2(config)#int vlan 10 CORE2(config-if)#ip add 10.10.10.2 255.255.255.0 CORE2(config-if)#no shut configure connectivity between CORE1 and R1 on CORE1 convert L2 into L3 port to assign IP address to it CORE1(config)#int gi1/48 CORE1(config-if)#no switchport CORE1(config-if)#ip add 192.168.1.1 255.255.255.252 CORE1(config-if)#no shut R1(config)#int gi0/1 R1(config-if)#ip add 192.168.1.2 255.255.255.252 R1(config-if)#no shut configure connectivity between CORE2 and R1, CORE2 using SVI create new VLAN and it's SVI on CORE2 for this connection, assign as access port   CORE2(config)#int gi7/48 CORE2(config-if)#switchport CORE2(config-if)#switchport mode acc...

use the same network from previous lab , just remove the 3560 and Po64 let's focus on the two link between CORE1 and CORE2, and take VLAN 10, 20 as an example before we go tot MST, there's something i forgot to mention on previous lab, this is one way to do the load balancing without using Etherchannel CORE1#sh span vl 20 ...
