3.126 QUERY_LOCAL_TOPOLOGY
All APPN nodes maintain a local topology database which holds information about the TGs to all adjacent nodes.
QUERY_LOCAL_TOPOLOGY allows information about these TGs to be returned.
This verb can be used to obtain either summary or detailed information, about a specific TG or about multiple TGs,
depending on the options used.
This verb must be issued to a running node.
