[j-nsp] Layer 2 ethernet redundancy?

[Dmitri Kalintsev]

Hi Tony,

A few notes, more of a general kind rather than strict guidelines for your
situation:

1) Your M20 *is* a single point of failure, so I presume it has dual REs
installed.

2) From the past experience, we have found that box redundancy *usually*
makes sense when it is deployed in geographically diverse locations (i.e.
different POPs, connected to compose a redundant topology). In cases of a
single-location deployments, it makes more sense to deploy a single bigger
box, but equip it with redundant everything. 6500 can be made fairly
redundant - different 10/100(/1000) cards for connections to your M20,
different 10/100(/1000) cards (maybe separate from previous ones) to connect
to your customers.

I'm not sure if it is a good idea to run 803.2ad to two different boxes.

Hope this helps, even if not much.

Regards,
