Hi all, can anyone help me with my design, we have a core router at head office and lots of 3550 switches, we have a remote office that connects via a les 100 circuit, basically out core router already has lots of secondary addresses so I was thinking of plugging the les circuit into one of our switches and putting that as a layer 3 port, then routing to that switch from our core, would that be ok, or are there other prefered methods ?
hi, there is no relationship between the les and sec ip,, basically the les plugs into our switch at the head office, the other end goes into a router, for the 2 sites to see each other they need a common subnet on the routers as its ethernet, but our core router already has to many secondaty addresses, I wanted to assign each end a 192.168.1.0/30 address, so what I was going to do was enable ip routing on a switch here, put the port the les sits on into a layer 3 mode, then from our core route to vlan 1 on this switch which will then route out the remote office, is this ok ?
can you by just putting a simple diagram? so that i can explain you clearly.
I have a similiar WAN setup in my organization where i hav set only a primary IP address in the router & created vlans in my layer 3 switch, all the routers fall under 1 vlan(eg. vlan 2) & all the server under falls on vlan 3, so that the client from the remote end will jus connect to the server ip address, because on the layer 3 switch , i have enabled inter-vlan routing.
Carl, basically, it works and agreed on Anand's suggestion. It is just to remind if there is another L3 routing / switching device will be connected to your core and exchange the routes, you have to design the routing plan to prevent backdoor or un-preferred path. And also need to check any L2 looping if they are located at the same VLAN.
Hi everyone, I would like to thank you in advance for any help you can provide a newcomer like myself!
