Installation is complete
=========================================================

Contiv UI is available at https://172.31.5.52:10000
Please use the first run wizard or configure the setup as follows:
 Configure forwarding mode (optional, default is routing).
 netctl global set --fwd-mode routing
 Configure ACI mode (optional)
 netctl global set --fabric-mode aci --vlan-range <start>-<end>
 Create a default network
 netctl net create -t default --subnet=<CIDR> default-net
 For example, netctl net create -t default --subnet=20.1.1.0/24 -g 20.1.1.1 default-net

=========================================================
