Any network segment that you don't fully control can be considered as a public network, so if you would encrypt traffic over a regular public network, do it for your case as well. NB: With full control I mean that you have full and sole control over any network devices that are part of the connection, so a port on e.g. a router or switch you don't own ...

It means Silicon Switch Processor a high-performance 7000 series router. According to the answer from dtlokee in this Cisco forum, it does stand for SSP. They use the Si for the "silicon switching", I guess it's a bit dated but that is how they would represent a switch doing L3 switching in hardware. Now I think it goes without saying that multilayer ...

In your question's scenario : No. It would either work (meaning that your ports have Auto MDI-X, which is built into Gigabit Ethernet, IIRC) just fine, or not work at all. Which means the cause of your problem is elsewhere.

Is there a (significant) signal quality difference between ethernet switches? No. A 1000base-t, do some switches allow longer cable runs than other switches? Nope. If you need longer runs, use fiber. Long runs of copper, even if under spec, put your equipment at high risk of inductive lightning damage, which is another reason to use fiber.

I have a cat5e ethernet cable running between two buildings with surge protectors on each end and it gets occasional carrier errors as reported by RouterOS which is based on Linux. I believe most of them are caused by lightning, as we can go all winter without a single carrier error, then when spring comes, we get a lightning storm and there will have been ...

Carrier errors stem from a problem at the physical level of the OSI model. The error is generated by the chip handling the signalling (the carrier wave is modulated to form the 0's and 1's). When the signal between peers is disrupted a "carrier" error occurs. Usually when the chip does not receive a normal link pulse (NLP) it will generate a carrier ...

Set the default route for hosts in segment 1 to the local route on segment 1, and that for hosts in segment 2 to the router on segment 2. This will be somewhat more painful if you're using DHCP, but since the network is segmented, it should still be perfectly possible.

It's possible you have a faulty network port, I've seen the exact same thing happen on a server due to a power surge (same symptoms of steady link light, and no connectivity). I'd suggest confirming this by setting a static address on the interface, and then seeing if you can pass traffic once it's connected. Something like (for example): auto eth0 iface ...

The problem is that you have three default routes. Since only one of the networks is connected to the internet, there should be only one default route. One of these three lines needs to stay and the others need to be removed. 0.0.0.0 0.0.0.0 192.168.1.1 192.168.1.17 10 0.0.0.0 0.0.0.0 192.168.2.1 192.168.2.51 ...

Thanks David. To remove these entries from route table I have used: route change 0.0.0.0 MASK 0.0.0.0 10.112.29.253 metric 1 What I saw is, if I am executing this command, The metric value for this route is incremented by 1 and the other 2 default gateways are getting removed from the route table. Not sure why. If you can explain that would be great. ...
