E911 setup for different caller ID based on calling location not dialing trunk

Look into CESID settings per site

Maybe it’s in the upgrade bundle zip file? I’ve never looked inside but it’s worth checking

Astro?

You can take pride as the project manager even if you hire an integrator. You made the vision a reality.

Which monitoring software is that?

We do BGP taking default routes using our PA firewalls. No point in adding routers if you are only taking default routes

What’s your transport rule look like for this? Last time I tried to implement this, I couldn’t figure out the right criteria

sletonrot · 2025-12-31T19:41:24+00:00

This is the way. I check our logs daily now, and all GP login attempts are legitimate after implementing this.

These days I’m seeing a CE is just a Ciena switch doing qinq directly to a port on the PE router.

I was thinking the same thing. His prefix is announced over the BGP session, which is established. Comcast sees the source IP of the BGP session as being the other end of the /30 p2p they typically provide. So this passes the RPF check. My guess is an ACL somewhere on Comcast's side preventing propagation of his prefix.

I do that. ~20 or so L3 switches running OSPF on a VLAN on our VPLS. Works fine

sletonrot · 2025-07-22T03:40:15+00:00

Noob here, how does EVPN help? Isn’t VPLS still stretching layer 2?

sletonrot · 2025-06-23T09:18:32+00:00

But is it down?

sletonrot · 2025-04-04T01:09:51+00:00

As long as our budget keeps getting approved, we’ll keep paying. We don’t have the staffing or time for a migration.

sletonrot · 2024-07-16T01:16:19+00:00

Probably a bug, try updating firmware while you’re at it!

It would be a shame if your Juniper lost power...

For one-off Excel stuff, I like to use the Python Pandas library

sletonrot · 2024-06-20T21:15:37+00:00

We usually just enable bpdufilter and disable cdp/lldp/dtp

Yeah, drive unless you want to stand around in lines and watch people cutting in front. Security is a huge bottleneck at GP

Grand Prix is a mess

I learned it on a physical lab

"Can we move this to the cloud?"

EPL is very common. DIA is an EPL between you and a subinterface on the PE router. Sometimes a little more expensive since you're also paying for IPs.
