Joining networks

[carl_t]

Hi all

When connecting 2 different networks together via 2 routers, Does one of the interfaces on one of the routers have to have an ip in the same subnet as the other router ?

would it only work by doing this ??

i.e

router A
e0 172.19.0.0
S0 192.228.3.0

router B

e0 192.228.1.0
s0 192.228.2.0

can anyone help,

basically how would you join to routers together, would you just point routers at each other, or would 1 interface need to be on the same subnet ?

I don't know a lot about this, but I have two Linksys routers on my network. The one connected to the Internet (cable modem) is in "Gateway mode," while the Internet one is in "Router mode."

The help on the router web interface says to use router mode if there are other routers on the network.

carl_t,
can you please list more detail about your logical setup?
what model routers are we discussing?

cisco routers.

Basically what im asking is that say you have router A on ip 192.228.1.1, router B on ip 172.19.1.1, If I had a serial or ethernet interface joining the 2 routers, woul one of the interfaves have to belong to the same ip subnet as the other router ?

i see two options

1 create a third point-to-point network between the two routers

2 change your addressing and use the unnumbered command. outlined here
