2 Routers 1 Network

[Pixelbew]

Today I received a second router from Verizon. The reason I needed 2 is because they told me I would be able to hook it up in my grandparents room giving them access to Ethernet or hardwired. However I learned this isn't the case. Now I wanna learn how to keep my main router which is connected in my room working but use the second router on the main network so they can also get good speeds. The problem is that the light on the router for internet will not turn on because our house is only allowed on ip. But the main one in my room is alright

plug the second routers wan port in the first's lan port

[dragoon20005]

the second router DHCP have to be disabled

 

also you need to set the second router to bridge connections

[conspiravision]

they probably want you to bridge the second router to the one actually connected in via coax.  You could probably bridge wifi or eth by doing what techguru said, beware of double natting.

[manikyath]

theres a few different ways of doing it:

 

bridge mode:

- put the second router in bridge mode, and plug its wan port in the first router's lan port

 

kludge bridge mode:

- disable the second router's dhcp, give it a free address within the first router's subnet (also placing them in the same subnet) and connect one of its lan ports to the first router's lan port.

 

double nat:

- make sure the second router is in a different subnet from the first router, then plug its wan port in the first router's lan port.

 

where subnet means the "192.168.x.0" thingy.

and usually dhcp is set by default to give addresses between 100 and 200, so a good rule of thumb is to put network devices on 1-10 (where your first router is 1 by default)

 

ending up with "192.168.x.y) where x is your specific subnet within the pool of class C subnets for local use, and y is the address of the device within that subnet.

 

 

PS: if you're a network guy facepalming at this, yes, i know its a very dumbed down explanation of subnets, but its so the less experienced can follow along.

I just have to say the very purpose of a router is to connect 2 or more networks together.

not really, its mostly a management box. in fact in some specific infrastructure forms the switches actually handle the interconnects between subnets.

Yes really.

 

The function of a router is to literally route traffic between networks.

Yes really.

sad to inform you my cisco training says otherwise.

while that is indeed one of its capabilities, it is not a given, and not nearly all of its capabilities.

Hmm my Cisco training and my job title disagrees. Rather than turn this in to a run off between who is more qualified you should really look up the definition of what a router is and it's function in computer networks.

 

A router routes traffic between networks. This is it's core function and all it does. There are different routing protocols to assist with this function, detecting path failures etc, and help reduce administration time/operator error but they do not change the core purpose of a router.

 

The device commonly referred to as a 'router' in home networks is not a router. It is an all in one device that has a modem, router and switch in a single box. Layer 3 switches have routing capabilities in them but are also not 'routers', but they can route.

Look, you can be pedantic all you like, I'm not going to argue with you. 

 

The fact is that the function of a router is exactly what it's name suggests. There are plenty of "routers" that have extra functionality built in and can perform all sorts of other functions and there are some switches that have built in routing features. That is not opinion. That is the basic operation of the entirety of the internet.

 

So, either you didn't pay very close attention in you "Cisco Training" or you feel like playing semantics, either way I'm not having any it.

its not as much that i didnt pay close attention, its mostly that the "trainer" himself wasnt cisco trained

 

most of it was self study. and most of the provided network examples actually have (managed) switches at key subnet intersections, whereas the router is usually kept closer to the top of the network where it meets the WAN.

 

EDIT: @leadeater has the bit i'm on about:

 Layer 3 switches have routing capabilities in them but are also not 'routers', but they can route.

in enterprice space L3 switches are more often used to "route" between the local subnets, whereas the main router (if any, i've seen setups without) is generally put up top, since thats where most of the work (traffic) happens.

Specific routers are rather uncommon now days in networks, in very larges ones they are still used as boarder routers that do BGP and sit in front of the firewalls. As you pointed out Layer 3 switches are the norm for internal routing and firewall appliances for internet routing.

well, a group of livestremers i follow (n3rdfusion, you may have seen them out on the interwebz ) actually used an L3 switch as their office's main "router" wetween WAN and LAN, and with two people streaming, it basicly shat itself. they put an enterprise router in place, and things are much better now.

(still makes me wonder why people in the USA need an enterprise router for a connection slower than my home network...)

I'd just chalk that up to bad configuration and not the equipment Also LTT is the only tech videos I watch and for entertainment only. Really enjoy the stuff Linus puts out but I don't exactly learn anything. Hope he does more ridiculous things like whole room water cooling, stuff that ends in epic fails seem slightly more entertaining

 

I use a L3 switch at home for my setup, Cisco SG300, and a FortiWifi 60D firewall. Both devices are not high up in the product ranges but are business grade and a true firewall, only issue I have is the inbuilt wifi is not that great range. Some devices just handle sharing of congested links better than others, routers typically assume this is going to be the case where a L3 switch is designed for LAN routing so shouldn't be an issue.
