v2.26.2 (21.07.2022)

NetworkReactionOnFailure enhancements

• Topolograph builds a topology based on OSPF adjacency and physical connectivity is hidden. But in some cases, we can assume that neighbors share the same media, in some cases - not. For example, if neighbors have a common DR - we assume that they are connected via shared physical media and then we emulate one of the edge failures between such neighbors - we emulate all edges down.

Mark all shared media links (which have common DR) is enabled

• Network reaction if a link/s goes down on dedicated media.
  If neighbors do not have DR or they have, but they are only two neighbors on the link, and when we emulate edge failure - we remove the only a single link between two particular neighbors.

Mark all shared media links (which have common DR) is disabled

v2.26.1 (14.06.2022)

Enhancements

• Asymmetric links counter is added in Unidirectional and Asymmetric links report

v2.26 (20.02.2022)

ISIS support is added for Cisco, Juniper, Nokia, Huawei

v2.25 (09.12.2021)

OSPF Watcher is added

Architecture

The Quagga container has network_mode=host so it sees the GRE tunnel, which is configured by Admin on the Linux Host.

Enhancements

Network reaction API

v2.24 (17.10.2021)

Enhancements

• save layout
• NetworkReactionOnFailure. unsimulate brokenness for clicked links
• Migrate hostnames automatically for new graph
• the shortest path between two nodes with the names
• give custom prefix to graphs/network state, i.e. 'before R123 upgrade', 'after upgrade'

v2.23 (07.09.2021)

Enhancements

• Ubiquiti support is added.

v2.22 (21.08.2021)

v2.22 (21.08.2021)

Enhancements

• HP (limited) support is added. Why limited - read on realize notes.

v2.21.1 (08.08.2021)

v2.21.1 (08.08.2021)

Enhancements

Fixes

• Error parsing OSPF LSDB output: host bits set

v2.21 (27.07.2021)

v2.21 (27.07.2021)

Enhancements

• Backup paths via 3d party locations.
  This report checks that if two locations are directly connected, backup paths should be only between two locations and do not go via third location as transit. Before running this report - it's needed to create groups (~site names/locations) and assign devices to groups. For example, there are two locations in France: the main site (EU_FRA) and the remote site (EU_FRA1). The same schema with offices in Italy. The main offices in France and Italy are connected to each other and have main (OSPF cost 10) and backup (OSPF cost 20) link.
  network scheme
  Remote offices have the main link (OSPF cost 1) to their main offices and backup link (OSPF cost 10) to the foreign office.
  If the main link between main offices goes down - the backup path goes via remote offices in different locations!
  
• fixes in ECMP backup paths report in v2.20

v2.20 (6.07.2021)

• ECMP backup paths report
• passed report
• failed report

v2.19 (20.06.2021)

• REST API (swagger) has been added in order to upload graphs.

The output returns:

• diff with previously uploaded graphs
• link to get all networks
• status about passed checks
