Hello everybody!I have got a network with 20 PC.I want to use the OSPF with DHCP.
This is my network:
RB 750 GL and RB 751 between there is a backbone.
And for the RB 751 connecting an outside 411U AP
And for my ap connecting the clients with 411 devices.
In the clients there is a bridge (wlan and ethernet) set to station pseudobridge.
In the network where is the place of the DHCP server?
On the 750 GL or the AP ?
Set on gateway device for your LAN.
It sounds to me like your talking about a local area network. OSPF is a dynamic routing protocol. Unless you need to route different subnets dynamically you don’t need OSPF. If you need a multi-path network on a layer 2 network (LAN) then you probably want the MESH feature not OSPF.
DHCP runs on a single layer 2 network (LAN) to configure the IP settings on devices and OSPF connects different layer 2 networks together through layer 3 networks dynamically. OSPF is also only helpful when you have a large number of routes needed for your network. If you only have a few LAN networks to connect then I’d recommend static routing rather then OSPF, static routing is no more complicated and you have fewer points of failure.
OSFP and DHCP don’t really relate to one another in that either can exist without regard to the other… OSPF and DHCP relate to each other kind of like a GPS map (dynamic routing table) vs a paper map and apartment numbers (dynamic address) vs a house number.
As long as the address exists, regardless of how it is acquired (assigned by the government or by the landowner), you can find it.
Also, regardless of the nature of your routing table you can find the address… a paper map (static routing table) or a GPS (dynamic routing table)
I realize my analogy is not perfect but the point is that the two factors are routing and IP addressing. OSPF is a type of dynamic routing (ie maps connecting distant locations) and DHCP is a type of dynamic IP addressing (addressing within a subnet).
Thank you very much for your information,i am a beginner in networking,and my network keep expanding,and that’s why i want to learning dynamic routing instead of static routing,and also i don’t want to use bridge only in the client devices.
Another question:my devices RB 750 GL,751,2011 are good for learing?I don’t have money for an RB 1100,1200… and in my network not need big bandwith,sorry for my english
This is our network:
I don’t know what your use is but I am running a WISP. As far as parts go here are some notes on what I use
I personally like the RB2011 routers and use them at smaller towers. The only time I upgrade from the RB2011 is when I’m using too much CPU. I wouldn’t change to using a larger router until I began using more then 50% cpu then I’d change to a RB1100AHx2 (which is the router I use for heavy usage). I often use two routers at a single tower, one for distribution and one for client connections. The only other devices I use are RB711xx-xHnD (for backhauling, AP’s and CPE’s) & RB250GS for small managed switches. I may find a use for OminTik’s or some RB750UP PoE routers.
For home use I would use a RB751U-2HnD.
For business use I use RB2011 routers with or without wireless depending on need.
I’ve also used RB1200’s, RB1100’s, RB4xx’s but I don’t find any use cases anymore so I don’t stock or deploy these units any longer.
Ok,i understand,but can you help set in our network ospf?
If you want to email me directly then I would be willing help you plan some things. I will reply with some task lists. My email is listed in words in my signature.
