I think I am overcomplicating myself in thinking how can I attach a server farm into my CORE P Switches.
My network in brief has 2 6509 switches as the P routers (10G between them) these then connect to 7609 routers which are my main PEs with Internet connectivity from several providers.
My first questions is: for redundancy should I have my 2 6509 core Switches (P Switches) connected to both my 7600 PE routers ? I mean, currently I have SW1(6509) connected to my RTR1-PE1(7609) and then this connects to multiple Internet service providers and clients(L3 VPNs). My SW1 then connects to my SW2(6509 on the other DC). This SW2 then connects to its own RTR2-PE2(7609) who also connects to multiple Internet service providers and clients(L3 VPNs). My question is should I add links from RTR1-PE1 to SW2 and from RTR2-PE2 to SW1 ?
My Core switches (SW1 and SW2) are pure P routers (they don't run BGP) and I want to attach a couple of switches (acting as access switches) with 3 or 4 server farms. My question is:
- I want these server farms to be accessed by some clients, therefore I need to put these server farms in VRFs, now how should I do this ? I'm thinking about 2 approaches
1 - Switching the traffic to the PEs and then (somehow ?) stick the server farm lans into VRFs
2 - Configure BGP on the 2 core switches and then bang them farms into the VRFs
3 - Configure the Access Switches as PE Switches/Routers and go from there ...
What do you think would be the better approach ? Or any other ?
Thanks in advanced
I agree for P role you just need an MPLS switching capable GE interface.
the VPLS capable interface/linecard is needed only on the PE nodes
This is another advantage of MPLS.
Hope to help
