We are presently using the config below to connect our Branch office1 LAN to the Head Office. We have Cisco2800 at Head office and Branch office1.
We want to connect the Branch office1 to another Branch office2.
the Cisco 2800 we are using has only 2 fast ethernet interfaces, so we decided to configure sub interfaces on one of the fast ethernet interface.
The Branch office2 will use Cisco871.
I attached here a simple network topology of our network and the configuration i made. (i tried this on my simulator, but i could not ping end to end.)
With the configurations below, will I be able to connect our Head office to the branch office2?
Is the configuration on Branch Office2 and 2950 switch ok.
Is my topology drawing ok, We use 2950 switch at branch office1.
