Hi,




Let’s say for example that you have a enterasys core, this will work with
any other equipment that is L3 capable.



And this is the logical topology:



Enterasys Core “fe.1.1” ----------------------300 mile (untagged
frames)----------------------“fe.1.1” B3



Let’s say that you have the IP's 192.168.0.0/16 in the B3





You should do P2P routing between your core and the B3.



So in the core you create a vlan 1000 and put it untagged in the port that
connects to the operator.



In the core:

Set port vlan fe.1.1 1000  modify-egress

interface vlan 1000

ip address 10.0.0.1 255.255.255.248

no shutdown

Create a route like this:

Route 192.168.0.0 255.255.0.0 10.0.0.2



In the B3:

Set port vlan fe.1.1 1000  modify-egress

Create the same vlan:

Interface vlan 1000

Ip address 10.0.0.2 255.255.255.248

No shutdown

Create a route like this:

Route 0.0.0.0 0.0.0.0 10.0.0.1



Create all the other vlans you want in the B3 and create the interface vlan
for them, the gateway for the computers.



This should do the trick.





Best regards,

Hugo Veiga
