Data Center Interconnect (DCI) 012
!
You are now required to perform Data Center Interconnect between DC1 & DC2.
The WAN core is multicast enable, but not MPLS capable.
You are allowed to use DC1-N7K1 & DC2-N7K1 to assist you in this task.
Only vlan 90 is required to be extended between DC1 and DC2 and vlan 80 will
stay local to the DC.
You will not need to create additional vlan for this task.
You are allowed to use multicast address range of your choice to achieve this task.
The rp address is 20.0.0.1 pim sparse-mode is running in the WAN core.
To property identify site DC1 & site DC2, you are free to configure a site identifier of your choice.

Topology:
Solution:
Configuring vPC+ between 5K and Downstream Switches:
!
Configure vPC domain 20 between DC2-N5K1 & 2 .
perform the following task:
1. Make sure N5K1 is always the vPC Primary switch.
2. Use Port-channel 200 for the Peer link
3. Do not add any L3 interface
4. Use Fabric path switch ID value 70.
5. use port channel ID 10 towards FI A
6. Use Port channel ID 20 towards FI B
7. Port channel to Down-Switch should be configured as IEEE 802.1Q trunk
interfaces that allow only VLANs 30,40,70,71.
8. Make sure that port channels 10 & 20 come up without wating for the
standard forward delay time.
9. in few months our server team will connect a singel-leg on VLAN 300 that's
connect to N5K-2 . Make sure that the interface does not go down in dual-active scenario.
10. Make sure the vPC peer devices are the primary deciecs as LACP & use
priority value 2500.
