-### External-AS topology operation
-
-Generate external-AS topology of the snapshot.
-It calls `generate_topology` function defined in `$MDDO_CONFIGS_DIR/<network>/<snapshot>/external_as_topology/<usecase>/main.rb`.
-
-* POST `/topologies/<network>/<snapshot>/external_as_topology`
-* option
-  * `usecase`: Usecase name
-  * `options`: [optional] Option parameters (Hash) for a function to generate external-AS topology
-
-```shell
-curl -s -X POST -H 'Content-Type: application/json' \
-  -d '{"usecase": "pni_te", "options": {}}' \
-  http://localhost:9292/topologies/mddo-bgp/original_asis/external_as_topology
-```
-
-`generate_topology` requirements:
-
-* accept `options` as an argument
-* returns topology data (RFC8345) of external-AS
-* NOTE: use `load` in `main.rb` to update these scripts without reloading netomox-exp process.
-
 ### Static Verification
 
 Verify all layers or a layer according to its network-type.
