Is anyone else in the north east seeing routing issues on frontier right now?  Unable to get to many websites. Trace route seems to complete fine but you can't bring up any content.

Is there anyone from AS 714/6185 that can reach out to me, AS 19016, to try and get traffic from your network to come to me via your Equinix IX connection instead of a transit connections.

Have had the question come up a few times, so I wanted to poll the community to see...

For those who are monitoring LLDP, how have you found the SNMP MIB support support for it on Juniper, Cisco, Brocade, Arista, and others?

Wondering if you've needed to resort to CLI scraping or APIs to get the data?

Thanks,

We use Observium for most of our SNMP monitoring, and it correctly pulls
LLDP and CDP data from all of our Cisco and Arista gear.

My experience with Juniper has been mixed, experience with 12.X and 13.X made me wonder if I had a poor understanding of how to do a proper decode or if Juniper's implementation itself had issues as I would often get incomplete results.

We've now grab over XML and have been pleased with that choice to the point I no longer see it as a "resort" but the most efficient way for us to move forward.  I used to open JTAC cases on each SNMP problem I'd come across [ CoS, mac-accounting ] and it generally wasn't a good use of our time.

I can't speak to Brocade (just haven't been to a customer recently who
has their kit and wants topology), but I've found support from Juniper,
Cisco, and Arista to be very good. As long as the device software load
is reasonably modern and LLDP is lit up everywhere, topology usually
just works.

We added LLDP support a couple years ago to OpenNMS' L2/L3
link-discovery service daemon (on top of CDP, IS-IS, and OSPF).
Everything is done via SNMP, for now anyway. If you read Java, you can
profit from our experience by sifting through the various LLDP-related
classes in our code here:

https://github.com/OpenNMS/opennms/

Tangentially, we've also been working on integration with OpenDaylight,
which pretty much demands going ReSTful to gather underlay and overlay
topology data.
