The purpose of this workshop is to augment the current dCloud offerings with a "from scratch" experience of the following:
- Setting up the Viptela control plane from scratch
- Using Enterprise certificates
- Bringing up the Viptela Overlay Network from scratch
- Integrating the Viptela Overlay Network with traditional infrastructure
- Setting up some common routing options
- Deploying template for automation
- Topology
- Scenario
- Deploy Topology
- Enterprise CA Setup
- Viptela Overlay Network Bringup
- Validate
- Routing Options
Enterprise has a single HQ and two remote sites. All routing at the remote sites is handled by the vEdge. The HQ does full internet peering, so the vEdge there is in a DMZ and exchanges routes with the HQ Core router via OSPF.
The Viptela control plane (i.e. vmanage1, vbond1, vsmart1) is hosted in the DMZ at the enterprise HQ.
Since this is being done in VIRL, the first interface all of devices have a connection to the flat management network. The subsequent interfaces are put into the simulated network. For Viptela, the management interfaces are moved to VPN 512 to simulate OOB management access. The following networks are allocated to the topology:
- 192.168.0.0/16: Enterprise private
- 192.168.1.0/24: Enterprise Site 1
- 192.168.2.0/24: Enterprise Site 2
- 192.168.255.0/24: Enterprise Loopbacks/TLOCS
- 10.0.0.0/8: Enterprise routable
- 10.0.0.0/24: Enterprise HQ DMZ
- 10.0.1.0/24: Enterprise HQ DC
- 10.0.255.0/24: Enterprise HQ P-T-P links
- 172.20.0.0/16: Internet Core
There are several nodes in the topology that can be used for testing:
- server1: A server sitting in the HQ data center that can be reached both internally from within the enterprise and externally.
- service1: A server sitting in an SP data center that represents a service that is not associated with the Enterprise.
- host1/2: These hosts are sitting internal to the enterprise.
The default username/password is admin/admin
NOTE: The Topology requires images for vmanage, vbond, vsmart, vedge, and CSR1000v
Install virlutils
Create a .virlrc:
VIRL_USERNAME=guest
VIRL_PASSWORD=guest
VIRL_HOST=your.virl.server
virl up -f viptela1.virl --provision
Verify the nodes are built (Note: These are the MGMT IP addresses to be used later, Note: Your addresses will be different!):

Since this lab was designed for dis-connected environments, we need to create our own CA. This can be done easily on any system with openssl installed (e.g. Linux/MAC):
First, we cd into the myCA directory to generate our private key (Note: You'll need to use the passphrase later to sign the other CSRs):
$ cd myCA
$ openssl genrsa -des3 -out myCA.key 2048
Generating RSA private key, 2048 bit long modulus
..................+++
.....................+++
e is 65537 (0x10001)
Enter pass phrase for myCA.key:
Verifying - Enter pass phrase for myCA.key:
Then we generate a root certificate:
$ openssl req -x509 -new -nodes -key myCA.key -sha256 -days 1825 -out myCA.pem
Enter pass phrase for myCA.key:
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) []:US
State or Province Name (full name) []:NC
Locality Name (eg, city) []:Raleigh
Organization Name (eg, company) []:CIDR
Organizational Unit Name (eg, section) []:SDx
Common Name (eg, fully qualified host name) []:
Email Address []: stevenca@cisco.com
myCA.pem is the CA root that you load into vManage and the vEdges when you are doing manual certificates.
Verify config file myCA.ext to be used in signing the CSRs later (already in the repo):
authorityKeyIdentifier=keyid,issuer
basicConstraints=CA:FALSE
keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
To do this through the CLI, ssh to the vManage and configure the following:
vmanage# config terminal

At this point, we have a righteous overlay. host1 and host2 can ping each other, but they cannot ping anything else at HQ or on the Internet. To allow hosts in the overlay to reach HQ, we need to form an OSPF relationship between edge-hq and core.

The router hq has already been configured to NAT all 192.168.0.0/16 addresses coming from the core router and going out to the internet.
To get the remotes sites to send traffic to the HQ, we need to tell OMP to advertise OSPF External (the default is an OSPF External route) routes on vedge-hq:
vedge-hq# config terminal
omp advertise ospf external
vedge-hq(config-interface-eth0)# commit and-quit
Commit complete.
vedge-hq#
We should then see the default route show up in vpn 1 on vedge1:
vedge1# show ip routes

We can check connectivity by running a traceroute on host1 to service1:
admin@host1$ traceroute 10.100.1.10
traceroute to 10.100.1.10 (10.100.1.10), 30 hops max, 60 byte packets

We see that the path indeed goes through the HQ.
Another option is to NAT at the site border. To enable NAT at the site border, we configure vpn 1's default route to vpn 0, then enable NAT on interface ge0/0. We'll use a CLI template to push this change out.
Configuration->Templates->Create Template->CLI Template:
- Device Model = vEdge Cloud
- Template Name = site_template
- Description = Site Template

NOTE: Since CLI Templates perform a replace (as opposed to a merge), we have to specify the entire config
Select Add
You should then see the CLI Template:
Goto More Actions (i.e. ...) and chose Attach Devices. Add vedge1 and vedge 2 to Selected Devices pane:
For each vedge1 and vedge 2 go to More Actions (i.e. ...) and chose Edit Device Template:
vedge1:
hostname: vedge1
system_ip: 192.168.255.14
site_id: 2
wan_ip: 172.20.0.10/30
wan_gateway: 172.20.0.9
lan_ip: 192.168.1.1/24
vedge2:
hostname: vedge2
system_ip: 192.168.255.15
site_id: 3
wan_ip: 172.20.0.14/30
wan_gateway: 172.20.0.13
lan_ip: 192.168.2.1/24
You should then see the variables filled out for Template:
Next->Configure Devices->Confirm configuration changes on 2 devices.->OK
We now see that the default route out from the site is through g0/0 using NAT:
vedge1# show ip routes

Finally, we can run a traceroute and see that we are going directly through Site1's Internet:
admin@host1$ traceroute 10.100.1.10
traceroute to 10.100.1.10 (10.100.1.10), 30 hops max, 60 byte packets

3 172.20.0.18 (172.20.0.18) 1.786 ms 1.869 ms 1.855 ms
This needs to be repeated for each site (or pushed with a Template).
