Topology
When accessing network devices, ensure the following IP configurations:
Pre-configuration on CML
| Device type | IP address |
| Transit Router for the topology ( IOSv or CSR1000v | 172.16.14.141 |
| WLC | Any Ip in Range 172.16.14.142-172.16.14.150 |
| DHCP Server | 172.16.14.3 |
Do not use any other IP for the router. Else the locally routed subnets won't be reachable
| Locally Routed Subnet for Wireless | 10.1.100.0/24 |
| Locally routed Subnet Gateway on Transit Router | 10.1.100.1 |
