Cisco SG300, Routing and Point To Point Link
Posted on 2014-02-19
I needs some help as im struggling with a new setup.
I have two sites, Site A and Site B
I need laptops from Site A to communicate with Site B (get a DHCP address from Site B from the DC)
The ISP has given me a Point To Point Metro Ethernet from Site A to Site B (not over internet) on VLAN 4
I have Two Cisco SG300s on each end and both are in layer 3 mode.
Site A, Port 4 is Tagged VLAN 4 ,IP 184.108.40.206, The cable from the ISP goes into Port 4 of Cisco
Site B Port 4 is Tagged VLAN 4, IP 220.127.116.11, The cable from the ISP goes into Port 4 of Cisco
I then plug laptops into Port 5 on both Ciscos which is untagged VLAN 4 on the same subnet and I can ping the two VLANs and Laptops.
I need to also carry VLAN 100 Site A to Site B.
If I plug a laptop on Site A, Port 2, VLAN100 192.168.100.1, I need to get to Site B Port 2 VLAN100 192.168.100.2.
As both sides are on the same subnet I cant seem to do routing as there on the same subnet.
Can anyone helps out with this.
Thanks in advanced
