how to analyze separate databases from separate IGP instances, at once?

[laimaretto]

Hello!

Some times one ABR has different IGP instances, meaning separate processes, which boils down in the end, to separate databases. A common scenario is seamless MPLS, where an ABR, or RouteReflector-in--line (RR-in-line) has an IGP instance to the core (if OSPF, area 0 will face the core) and separate instances facing the access (but since the processes are different, a design could use area-0 to the core, and also area-0 to the access, since the databases are independent).

So, a RR-in-line will have a separate DB with backbone information and a another DB with access information.

Which would be a good way of analyzing this scenario? Could I concatenate the DB files into one? Will topolograph handle that? Is there a good way of having such information in the same plot?

thanks!

Hi @laimaretto , Sure, you can put LSDBs from different OSPF's processes into one single file and upload it. It worked for me at least ;) Please keep me posted how it works for you.

whoops, I tested on two ABRs with (Area 0, Area 1) and (Area 0, Area 2) outputs and found that Area 0 links are duplicated. Working on fixing it.

Hi @laimaretto , I've just released v2.34 version with multi LSDB support. Please check. Appreciate for your feedback.

Release notes:
If a network has multiple areas, it is needed to get LSDB output from multiple devices and save it into separate files. Example below uses two LSDB outputs saved in the lsdb_samples folder.

• Cisco_ospf.txt
• Juniper_ospf.txt
  Python sample code:

  
  import requests
  TOPOLOGRAPH_HOST="127.0.0.1"
  TOPOLOGRAPH_PORT=5000
  TOPOLOGRAPH_WEB_API_USERNAME_EMAIL="your login"
  TOPOLOGRAPH_WEB_API_PASSWORD="your password"
  from pprint import pprint as pp

lsdbs_attr_ll = [] lsdb_dir = os.path.join(os.getcwd(), 'lsdb_samples') for vendor_name, protocol_name in [('Cisco', 'ospf'), ('Juniper', 'ospf')]: f_name = os.path.join(lsdb_dir, f"{vendorname}{protocol_name}.txt") with open(f_name) as f: lsdbs_attr_ll.append({'lsdb_output': f.read(), 'vendor_device': vendor_name, 'igp_protocol': protocol_name}) r_post = requests.post(f'http://{TOPOLOGRAPH_HOST}:{TOPOLOGRAPH_PORT}/api/graphs', auth=(TOPOLOGRAPH_WEB_API_USERNAME_EMAIL, TOPOLOGRAPH_WEB_API_PASSWORD), json=lsdbs_attr_ll, timeout=(5, 30)) pp(r_post.json())
