Bridging for a data connection

Now if I just have layer2 connectivity for LAN end to end.

Say LAN1-------WAN-------WAN-------LAN2

The connection is a bridge or layer2 which means no ip address is configured on the Wan. Then how can I access LAN2 from LAN1. Can ip address if connected as a layer2 for data connection have ip addresses

Re: Bridging for a data connection

That is very simple. You use the same network addressing scheme for both sites. Take care that networks do not overlap.

[192.168.0.0/24][R1]---/---[R2][192.168.0.0/24]

hosts 1 through 127 hosts 128 through 254

Re: Bridging for a data connection

Do you mean that we can configure ip addresses on the lan if there exist a data link connection from Lan to Lan.

That means ..

R1------------ BRIDGE --------------R2

| no ip on Wan Network |

| |

IP:192.168.1.1/ 192.168.128.1

from R2 I can telnet R1,192.168.1.1 from R2, 192.168.128.1 and connection will be opened

and it will work ...

Thanks in advance

Re: Bridging for a data connection

You can avail the above scenario provided you use the same addressing scheme throughout your network.

ie. it has to be in the same subnet.
