PE Router design

Answered Question
May 10th, 2010

Hi,

I need some help on designing a PE router for our MPLS network.

My requirement is 2 port STM4 and some Ge ports.

Currently our vrf is just 10.

I prefer the 7600 router series. is this enough?

I need your suggestion, on what processor module and what STM4 module to use.

Currently there are 2 kinds of STM4 that i can use, OSM module and SPA module.  What is the difference between the two?

Thanks in advance for the help!

I have this problem too.

Hello RCandeloza,

C7600 can support 1000 VRFs and a lot of GE ports

you should use a sup720 3BXL or better

OSM are older linecards may be not supported in some recent IOS images, SIP linecards with SPA port adapters are the current WAN modules for C7600 so you should go with these ones
