All right, let's go ahead and answer these questions first and foremost, which
type of
load balancing should be used to statically map our voice server IP traffic.
So if it's coming in here, we want to make sure that it goes out the MPLS side,
we could
use our active standby application pinning.
Remember the word pinning there means that we're statically mapping it.
So it's going to be an active standby situation where we will always use MPLS
so long as it's
up.
We want to care about the metrics and we'd have to look at the application SLA
option
because otherwise we are simply going to always use MPLS so long as it's online
.
Where's BFD deployed in the diagram?
Again, BFD goes out every single IPsec tunnel.
So it's going to go out and then hopefully we get responses back in every
single one
of these tunnels, whatever edges that we are connecting to, we will be running
BFD.
Lastly, if we're using a multi-region fabric, what type of edge devices are we
connecting
to upstream?
Well specifically, we would be connecting to other regional edges.
So for example, maybe a couple other sites that are inside my own country or
inside my
own continent at least, somewhere within my region, however my company defines
that.
But we'll also be connecting to the core devices.
So maybe this, these couple of IPsec tunnels connecting me to a core device,
maybe these
go to the other edges that are in my region.
Typically, if we have two circuits like this, we're trying to connect to the
same edges
because that allows me to maintain redundant connections to every single site.
That's what we were looking for with that question.
Mostly we're just trying to make sure we understand how architecturally we'd
build this out, where
BFD plays into it.
Naturally, we also talked about zero touch provisioning, which would help me
bring all
these edges online, but certainly taking away from the conversation, the role
of BFD, how
we can apply that, especially within a load balancing conversation, and then
how our tunnels
get formed in a multi-region fabric, all of that is very important for us to
understand
as we move forward.
