Procurve E3800 connection between two buildings - routing with only 1 mac address (LanLink)

[Ogret]

Hi @ all

I have a issue with the connection between two buildings. I use the following Hardware E3800.

Configuration Site A:

IP Routing Enable
192.168.1.0/24 VLAN 6 Client
192.168.2.0 /24 VLAN 7 Server
192.168.3.0/24 VLAN 8 DMZ

ip routing 0.0.0.0 0.0.0.0 192.168.10.254 = 192.168.10.254

Configuration Site B:

IP Routing Enable
192.168.1.0/24 VLAN 6 Client
192.168.2.0 /24 VLAN 7 Server
192.168.3.0/24 VLAN 8 DMZ

I have a LanLink from ISP Provider (Layer 2) and i will connect between the two buildings without a router. Swisscom will not, that i send more than 5 mac address over this connection. How i make a configuration with Layer 3 on the E3800?

Could someony help me?

Change SiteB to:

192.168.21.0/24 VLAN 6 Client
192.168.22.0 /24 VLAN 7 Server
192.168.23.0/24 VLAN 8 DMZ

Create a new VLAN99 for 192.168.99.0/24, put .1 on SiteA and .2 on SiteB, change the link so it is untagged in VLAN99.

On SiteA switch, add routes for 

192.168.21.0/24 --> 192.168.99.2
192.168.22.0 /24 --> 192.168.99.2
192.168.23.0/24 --> 192.168.99.2

On SiteB switch, add routes for 

192.168.1.0/24 --> 192.168.99.1
192.168.2.0 /24 --> 192.168.99.1
192.168.3.0/24 --> 192.168.99.1

Can you ping it from a different 192.168.2x.0 subnet?

[Ogret]

Sorry my mistake. The issue was that the Port is only enable if you stack a RJ45 in the port.

Now it works.

Can I see the MAC traffic between this 2 E3800 Switches on Port 192.168.99.0?

Swisscom send me a email, i use more than 5 mac-address but the routing works, any idea?

Show ARP on VLAN 99 on both Switch
