[FROG] IS-IS Error

Fri Apr 17 06:04:01 EDT 2020

Hi all.

I'm almost there getting IS-IS to work without issue. I'm now faced with
the following error log:

2020/04/17 10:02:01 ISIS: IS-IS bpf: could not transmit packet on em0:
Input/output error
2020/04/17 10:02:01 ISIS: [EC 67108865] ISIS-Snp (1): Send L2 PSNP on
em0 failed

This repeats every second.

Anyone know what this could be?

Systems is FreeBSD-12.1-RELEASE-p3.

Despite the error, IS-IS is running and routing is good, talking to a
Cisco IOS XE implementation on the other side. So the error is throwing
me off.

Mark.
