[FROG] [dev] Problem in FRR with ldpd

[Phil Wiggins]

Shruti,

What you are showing (systemctl output in the attached screen captures) is
the host PC and not the emulated environment in CORE.  When you are running
CORE, a startup script is created for FRR which generates the software to
be run inside each CORE container (router icon).  I would strongly
recommend that you turn off FRR on the host PC and only use the emulated
environment in CORE for this type of emulation work.

When you launch a shell in CORE for a particular router, run vtysh -c 'sho
daemons'.  If ldpd isn't showing, there's probably a startup error of some
sort.

Just double-checking the frr startup script in CORE (
https://github.com/coreemu/core/blob/master/daemon/core/services/frr.py#L255
):

   - It looks like ldpd is being called and communication with the daemon
   is being set up.
   - you can manually start the daemon inside the CORE router using the
   command prompt  'ldpd'; it should log any startup errors to stdout
   (terminal)
   - if that works for you, then at Line 216, add ldpd to the list of
   daemons to be started.  It looks like ldpd didn't get put into the startup
   list.

You can file a bug report at https://github.com/coreemu/core/issues or,
even better, submit a patch.  Blake is pretty responsive to fixing items.

Cheers,

Phil
