[f-nsp] Policy based routing?

[Nick Morrison]

as an example of why you might decide to go out on the PBR limb...

in a company's network, you may have:


a network edge (foundry) with servers with lots of data on them

-- a distribution layer (foundry)

----  a core layer (foundry)

----  a core firewall (vendor X)

-- a dmz distribution layer (foundry)

a dmz network edge (foundry) with servers with lots of data on them


for most things, this is fine.  data is routed through the whole kit and
kaboodle.

the core firewall, though, is not capable of 10Gbps (or higher),

so for *some* traffic - massive file transfers, etc - we want to skip the
firewall layer.  for this, we'd use PBR on the core layer and on the dmz
distribution layer, using a (say) 20Gbps link between the two (configured
with a /30 - the far side is the next-hop.)  nothing but the selected
special traffic is allowed over this 20Gbps link; everything else goes
through the firewalls.


for musing.
