BLT

Getting started with BLT 0.4

As usual you can grab the binary (Java multiplatform) here, or the source code from Github here

Then you have to :

unzip the package
generate a key for the embedded HTTPS server (read INSTALL instructions)
modify "blt.conf" to fit your needs

From now on you can start the program in single run mode from the console:

bob@ws01:~/blt-0.4.1$ java -jar blt.jar
Starting Blt version 0.4.1.
17:26:48.910 [main] INFO  onl.netfishers.blt.Blt - Starting Blt
17:26:48.924 [main] INFO  onl.netfishers.blt.Blt - Will go on logging to the console.
17:26:55.917 [New I/O worker #1] WARN  onl.netfishers.blt.bgp.BgpService - no valid IP address attached to this link
will fall back to BGP LS only mode for the following link:
<-- localId: 0001.0002.0131
--> remoteId: 0001.0002.0132 protocolId: ISIS_Level1

will fall back to BGP LS only mode for the following link:
...

A lot of messages now pop up, depending on the verbosity level you have set up in "blt.conf"

Then you can try the UI based on the URL you have set up in "blt.conf", default credentials "admin/admin"

My setup is based on four routers running ISIS and OSPF, so I have configured both of them as BGP LS speakers, and I run two topologies inside BLT:

BLT Admin mode

As you can see, OSPF map has an optional green icon, allowing me to switch to Google Maps view:

BLT Legacy view

ISIS topology has not the same option because one of the routers (here R381), has no valid GPS coordinates in sysLocation OID

That is: you must provide valid GPS coordinates for this mode to get enabled (see "blt.conf")

If you choose to navigate to the new Google Maps mode, you have the same monitoring features available:

BLT Admin mode
