Need help with core and border design for Web Hosting company please..

m-abooali · ‎04-10-2008

I have started in this company for 4 days now and have been given a task that has already been started by two other engineers but they had left due to some issues and now I have been brought/hired and been given this project. I don't have any background on this and no documentation was left after the two engineers had left!

I have attached a drawing that shows what needs to be done and I have no idea of where to start? this is web hosting company.

from what i have gathered, it seems that they use EIGRP as IGP and BGP at the border with two OC3s connecting them to the outside world (Private VLANS also been used for some customers).

Now, They have purchased a Dark fiber ring to connect them to their datacenter using the provider's network as transit. the equipment have changed to accomodate for two new Ethernet- gigi WAN links to get them to their dtacenter - basically connecting them to their upstream provider and BGP will be used. they still want to use EIGRP between the two core 6506 switches (RJ-21)! and BGP on the two Cisco 6509 Switch/Routers.

thats all I know and the time is very short. they are expecting me to follow the same dates that were previously planned and I have to come upto speed with this prgect. this dark Fiber is basically a ring.

Please see the diagram that shows the old or current and the new/Planned infrastrutures. I have not worked with switches/routers with RJ-21 connectors on blades and have no idea of Private VLANs. I have done VLANs a lot of time, L2 and L3 but not private vlans.

I am lost and need help please. I can use all the help that you possibliy can extend to me and I am greatful for that.

I am going to post this in the WAN Routing and Switching Section as well and forgive me if this isn't right!

Regards,

Mike

I am also, adding the diagram that was left by the two engineers who originally designed and planned this transition. this may help you understand what is going on hopefully.

th eextend of my inofrmation is really what I have provided.

1- BGP between border routers to provider 6506

2- EIGRP between Core routers 6509

3- PVLANS on the 6509s

4- HSRP for failover and redundancy

5- Spanning-tree for loop prevention.

nothing more than this is available. i still get lost in the building being here only three days (today is my 4th day) and i don't even know the business model and how they do things, traffic flow, L2/L3 stuff, etc.

pls see the new atachment.

Thx,

Mike
