This is not the first network topology drawing tool that use the NeXt UI. The NeXt UI Toolkit is an HTML5 / JavaScript based toolbox for networked web applications. https://creations.devnetcloud.com/detail?cid=1e4a9f92-deea-11e7-9d2f-aed03b171102 https://github.com/NeXt-UI
This small project contains Python script and templates for parsing IGP LSDB (OSPF and ISIS) such vendors as Nokia, Juniper, Cisco and Huawei, creating topology in json format for drawing network topology in NeXt UI and showing it in your browser.
Using this script is very easy.
- Please load a file with LSDB in directory
/test_files. Currently contains the few tests files. - In the file config.yaml specify the path and name to your LSDB file, vendor name, where did you get the LSDB file, and type of IGP (OPSF or ISIS).
- Install requirements from
requirements.txt. - Runnig the script
igp_topo_light.pyand enjoy your network topology in a browser.
Currently supported:
- Nokia - OSPF and ISIS;
- Juniper - OSPF and ISIS;
- Cisco - OSPF and ISIS;
- Huawei - OSPF and ISIS.
Following commands outputs are possible for parsing:
Nokia:
show router isis database detail
show router ospf database type router detail
Juniper:
show isis database extensive
show ospf database router detail
Cisco:
show isis database detail
show ip ospf database router
Huawei:
display isis lsdb verbose
display ospf lsdb router
