| # YDK C++ BGP JSON Samples for XR | ||
| ###Prerequisite | ||
| First install the [system requirements](https://github.com/CiscoDevNet/ydk-gen#system-requirements). Then follow the [ydk-gen README](https://github.com/CiscoDevNet/ydk-gen#usage) and generate/install the C++ core, [ietf bundle](https://github.com/CiscoDevNet/ydk-gen/blob/master/profiles/bundles/ietf_0_1_1.json) and [cisco-ios-xr bundle](https://github.com/CiscoDevNet/ydk-gen/blob/master/profiles/bundles/cisco-ios-xr_6_1_2.json). | ||
| ### 1) Build the sample apps | ||
| ``` | ||
| $ mkdir build && cd build | ||
| $ cmake .. | ||
| $ make && sudo make install | ||
| $ cd .. | ||
| ``` | ||
|
|
||
| ### 2) Run the apps | ||
|
|
||
| Note: `-v` will turn on verbose mode | ||
| ``` | ||
| $ cd build | ||
| $ ./bgp_xr_write ssh://<username>:<password>@<host address>:<port> [-v] | ||
| $ ./bgp_xr_read ssh://<username>:<password>@<host address>:<port> [-v] | ||
| ``` |
