I award ratings when I've tested it to make sure I don't send people on red-herrings. I've tested this and it does indeed work, great stuff thank you so much. Regards Andrew.

Ah I see what you mean now, that makes sense. If I were to set the "last" switch (172.20.1.1) as the OSPF default-information originate always as you stated and then this switch has a static route of 0.0.0.0 0.0.0.0 172.20.1.10 in it, would this then work? (this would save me having to manually set the default route on each device and would allow for ospf multiple paths to work) Thanks again Andrew.

Hi Soroush, I see what you mean now, however I don't think this will quite give me what I want. First of all, the router is not that clever, it doesn't support OSPF (hence the static routes on it). Also, I want to be able to use differen default routes for the different switches on the network. The switches in this diagram are actually spread over three buildings and I want to be able to give them their own local WAN presentations at some point, but for now they will run from head office. So everntually I need to be able to set this at the switch level, not just the OSPF level across all buildings. Does that make sense? Andrew.

Sorry, when I say "first" I meant the switch that the server is plugged into, when I said "last" I meant the last in the chain, i.e. the one the router is connected to. 8.8.8.8 is the google public DNS server which I am using to test internet access. I'm afraid I don't quite follow your last point, could you please elaborate? Thanks for your help Andrew.

Hi, I have attached a diagram that I hope explains the topology sufficiently. All the switches are 3560s and the router is a cyberoam. The Switches are all connected using routed ports on layer 3. The router at the end has a static route for the entire 172.16/12 range which points back to the final cisco switch in the chain. I have a static route set on the first switch for 0.0.0.0/0 172.20.1.10 which I thought would mean that any device using this switch as its default gateway would have it's wan traffic sent out of the router, however this isn't happening. If I ping 172.20.1.10 from the server I get responses straight away. If I ping the server from the router then it works fine too. I can also ping the router from each of the switches and visa versa. However, if I ping 8.8.8.8 from the server I get "172.31.254.106 No route to host". I'm completely stumped by this as the route has been given to it already hasn't it? I'm even more confused as the final switch in the chain has the same static route in and pinging 8.8.8.8 works fine. Does anyone have any suggestions? Regards Andrew.

I'm sure this is very basic question, but I've seen the attached network design quoted in lots of places (cacti weather maps etc) but I'm not sure how people do it. Basically it's 4 switches with each switch connected to the other. Is the purpose of this load balancing or redundancy? Also, how is this implemented? I read somewhere that someone was using OSPF, but wouldn't that mean that you couldn't have a VLAN span two switches? Thanks for any feedback.

Thanks, that's all very helpful. The one link is 1gb and looking at the prices I'd need to spend £10k to get a router to do this. Juniper seem to do one for £1,400 though so I'll look into that. Thanks.

Hi, I have a 3560x which has a 60 day trial license on it for IP Base, how do I activate this license? Thanks Andrew.

Hi Joseph, Thanks for that. I don't like "Auto" things as I like to know how they're setup. Can you get me started with the config for the 4 egress queues you refer to? How do I assign traffic into a particular queue? (I've never done QoS before) Thanks

I have two Cisco 3560x switches running IPBase on different sites joined by a 1gbps connection with routed ports. I have video data totalling 80mbps in site A that is crucial to arrive at Site B regardless of any other traffic on the network. What I would ideally like to do is reserve 100mbps on the link from A->B which is only allowed to be used for this traffic. The traffic starts in a subnet of its own and finishes in a subnet of its own (i.e. only the video traffic is in the VLAN on each switch with data and voice in different subnets). Any help is appreciated Thank you

Thanks for the great replies. As the network is private and needs to shift around a lot of data I think I'll go with switches. Thanks.

Hi, I'm implementing a multi site network and intend to use OSPF to do it. The links between each site at either 100mbps fibre or 1gbps My question is, is this better to be done with switches (3560x with IP Base) or routers (2921)? What are the main pros/cons of each? I understand that the 2921 can do far more with securtiy between sites and probably has more advanced QoS(?) Thanks

I am setting up a link between buildings that uses wireless links. I'm using Layer 3 routed ports on 2 3560 switches to handle the routing between sites. Normally I would just put these in a /30 and then the switches handle the rest. However, the wireless access points have a web interface for managing them that I want to be able to access, but it's only available on the single NIC that also carries traffic. What would be the best way of making this work? Should I make the link a /29 and give the access points an IP in the same range? If this is the case what do I use for the default gateway for the access points? I have included a diagram to try to explain the issue clearer. The IP addresses in black are what I would do if this were a standard cable (and indeed this will work, but I wont be able to access the admin interface of the wireless AP) and the red ip addresses are the alternative if I use a /29 (but as I said, I'm not sure what to use for the default gateways) Thanks for any / all help. Andrew.

Ok, I never found out what the problem was with this. I just cleared out all my settings, did them again and now it works. There must have been a mistake somewhere, but I couldn't work it out. Thanks for all the suggestions.
