Now that you have Multi-Site Schemas configured across ACI fabrics and VMs running, it is time to test the connectivity between the VMs across the ISN.
In this section, we will apply some concepts from earlier in the lab to attach VMs to the proper VMware vDS port-group that was created by the MSO
controller.
Since these endpoints will reside in the same EPG, no contract was required when creating the Schema Template. However, if you use MSO to create various
EPGs with
endpoints in different EPGs, like normal from the APIC point-of-view, hosts in different EPG will not be able to communicate
between each other unless there is a contract defined between them.
Step 1 - Edit POD01-DB-SRV VM Settings
Return to VMware's vSphere vCenter and login if necessary. Locate your POD01-DB-SRV VM.
Right-click on your POD01-DB-SRV VM
In the popup menu, select Edit Settings
Step 2 - Select vDS Port-Group Provisioned From MSO
In the Edit Settings of your POD01-DB-SRV VM, locate Network adapter 2:
In the dropdown menu of Network adapter 2, select Show more networks...
On your vDS, locate your vDS port-group created via the MSO controller: msite_p01_tenant|msite_p01...
Select the vDS port-group created by the MSO controller: msite_p01_tenant|msite_p01...
Step 3 - Finish Settings Update with New Port-Group
Complete adding your POD01-DB-SRV VM to your vDS port-group created via MSO.
In the Edit Settings window, click Ok to apply modifying the Network adapter 2's network
Step 4 - Login to LAB-SRV1
Click on the console ICON on the left to start the connection to the LAB-SRV1 Username: pod1u1 Password: cisco.123
cp ~mtarking/change_rmt_pg.py .
Step 5 - Run Python Program
Using the CLI run the python program change_pg.py
python change_rmt_pg.py
Please enter User, Password, POD using commas:
pod1u1,cisco.123,1
Verification:
[pod1u1@lab-srv1 ~]$ python change_rmt_pg.py
Please enter User, Password, POD using commas
pod01u1,cisco.123,01
Connecting to 10.0.226.193
Getting into pod dc_pod01
Reconfiguring Network adapter 2 for virtual machine POD01-RMT-SRV-01
Reconfiguration Network adapter 2 to msite_p01_tenant|msite_p01_ap|msite_p01_epg for virtual machine POD01-RMT-SRV-01 completed successfully.
[pod1u1@lab-srv1 ~]$
Step 6 - Exit lab-srv1
Before proceeding to the next section, it is important to exit pod1u1@lab-srv1
exit
pod1u1@lab-srv1 ~ exit
Step 7 - Login to POD01-RMT-SRV-01
Click on the console ICON on the left to start the connection to the POD01-RMT-SRV-01 Username: root Password: cisco.123
Step 8 - Configure the IP for the Second NIC on POD01-RMT-SRV-01
During this step we will be configuring the static IP address of the second NIC
After we have modified the ip address and added the static route, we need to restart the network services
in order to take effect the previous changes.
systemctl restart network
Step 10 - Login to POD01-DB-SRV
Click on the console ICON on the left to start the connection to the 10.0.145.5 Username: root Password: cisco.123
Step 11 - Configure the IP for the Second NIC on POD01-DB-SRV
During this step we will be configuring the static IP address of the second NIC
After we have modified the ip address and added the static route, we need to restart the network services
in order to take effect the previous changes.
systemctl restart network
Step 13 - Ping your DB VM's Default Gateway (192.168.101.1)
From your POD01-DB-SRV VM, ping the anycast gateway that has been provisioned to ACI through the MSO Schema.
ping 192.168.101.1 -c 3
root@pod01-db-srv-01 ~]#ping 192.168.101.1 -c 3
PING 192.168.101.1 (192.168.101.1) 56(84) bytes of data.

rtt min/avg/max/mdev = 0.164/0.177/0.193/0.012 ms
Step 14 - Ping your Remote Site VM (POD01-RMT-SRV-01)
From your POD01-DB-SRV VM, ping your POD01-RMT-SRV-01 that resides in the remote data center (dc1).
Terminal
ping 192.168.101.11 -c 3
root@pod01-db-srv-01 ~]#ping 192.168.101.11 -c 3
PING 192.168.101.11 (192.168.101.11) 56(84) bytes of data.
