Re: Dark Fiber question [7:769]
JP #1) Here's another option, GSR with OC-48 optical regenerators. http://www.cisco.com/warp/public/cc/pd/rt/12000/prodlit/corbr_ov.htm Then you're going to need facilities to house these regenerators. #2) One advantage of leasing dark fiber is your company could implement a DWDM solution and pay as you grow. You could add an OC-48 as you see fit by simply adding lambdas (OC-48 wavelengths). It all depends on how scalable you want your network, and if you would meet these requirements for this much bandwidth. David and Andyh both brought up good arguements for leasing from a carrier. 50ms APS on carrier OC-48 Ring. Just my 2 cents...

Hello Everybody! I was just curious if anyone has scheduled to sit in on the CCIE Optical Beta? http://www.cisco.com/warp/public/625/ccie/ccie_program/whatsnew.html I see the beta is only US$50. After reviewing the CCIE Blueprint, does anyone have any thoughts on how difficult the exam may be? I see the Blueprint lists the Cisco ONS 15900, but I believe I saw a press release that this product has been discontinued? Can anyone verify this? Thanks In Advance! Happy Easter!

Re: OSPF
While I see what you are saying.

Re: OSPF design question re: location of Area Border Router
David, you put the ABR at the main location with one interface (usually LAN) in area 0 and the other in the area created for the remote location. All interfaces at the remote location would then be associated with the area created for this new site. The ABR is located at the main location because as you said you do not want to expand area 0 over the WAN link.

Re: IBM ATM Switches
The IBM 8265 is a good switch. It was not OEMed from Xylan (that was the IBM 8274 / Xylan Omniswitch) with the 8265 you would also need the MSS for ATM/LANE configurations.

Re: One last Layer3 switching ?
You are correct in the part of 24 separate collision domains which also allows you to put the 24 ports in Full Duplex mode. The part about 24 broadcast domains would only hold true if each port were in a different VLAN no 2 ports in the same VLAN. I.E. a port is an isolated collision domain and a VLAN is an Broadcast domain. Scott NetEng wrote: > I understand the layer3 switching concept, but what happens to broadcast > based services?

Re: help with 2948G-L3 switch
I have never had to use an ip helper address in an NT/95/98 environment to date. The ip helper address has only been needed to get to the DHCP server for an IP address. Accessing the PDC has never required one.

Are the workstations in the .5 network setup correctly for WINS, proper domain, ect. What is the error message you are getting when the .5 segment workstations are trying to log on?

Re: LAN design
All things taken into consideration a core in many cases will be better served at layer 2, with routing taking place at the edges of the core at the access and distribution layers. This moves the path selection processing to the edges and leaves the core as a layer 2 transit area normally with large pipes between the distribution and access layers of your design. Layer 3 switching may change this to some degree. Scott Ron Stark wrote: > Hi people, > > I have a design question that I was wondering if someone could shed some light > on.

Re: IBM Gurus - Please Help!
DSLw or DSLw+ is the way to encapsulate SNA into an IP packet for transport across the WAN. It will require you to create a peer connection form one side of the WAN to a router on the otherside. once this is done the SNA will be encapsulated into IP for transport to the peer partner. In setting this up you may want to consider having the router at the remote location establish the peering connection. That will reduce the cycles on your main networks router, should a WAN connection, DSU, or interface fail. You will still need bridging turned on, but will not have to bridge other protocols unless you need them. Scott Don Dettmore wrote: > I need some help from somone that knows SNA and DLSW.

You can do this with the "os2ping" command. That is if you are running OS/2. Scott Peter Gray wrote: > How can I ping the MAC address of a host. Is it just like pinging the ip > address.
