Fail safe edge router / routers

Unanswered Question
Apr 15th, 2009

Just wanted some opinions on a fail safe edge router design. using 7500 gear:

A -

Single router, two upstream providers with dual RSP.

B -

Two routers, one upstream provider per router.

I have this problem too.

Hi:

Two routers would be the better approach. You have equipment redundancy, plus redundant service providers.

Am I missing something?

I 100% agree, I just wanted to make sure I wasnt missing something....

Adding to this,

What are your feelings on what I will call a "data center switch design"

Single "end of rack switch" Lets say 6500 with redundant supervisor cards.

or

Two redundant "core" switches, each with a link to each "top of rack switch"

I like the latter, but again just wanted some opinions.

Thanks!

Dan:

I would always go with the dual chassis approach over the single chassis with dual SUPs, if the budget allows. I think its pretty straighforward.
