Hi, everyone, and welcome back.
Now, in today's video, we are going to discuss about the transit gateway and direct connect.
Now, at a high level overview, whenever you have a direct connect and transit gateway, then you can
make use of that transit with attachment.
Now, if you're making use of transit with to the direct Connect Gateway, it allows you to connect
to multiple transit gateways over here.
Now, one of the benefits here is that you can achieve multi region as well as multi account based functionality.
So you have two regions here, US East one and Mumbai region.
Vinod Transit Gateway works at a regional level, so you have a transit gateway for US East and transit
Gateway for Mumbai.
You associate it with a DD gateway here and you can make use of the transit with attachment for the
overall connectivity.
Now a few pointers that we need to note First one is that the transit gateway can only be associated
with a direct connect gateway attached to the transit virtual interface.
This is something that you need to note.
Second point is that you can associate a transit gateway owned by any account with a direct connect
gateway that is owned by any US account.
This is something that we have already seen.
And third important point is that you can create only one transit virtual interface for any direct connect
connection.
Now, in case if you'd like, you can also make use of VPN on top of direct Connect, which allows you
to perform the end to end encryption of the traffic.
So you have a transit gateway, you have a direct connect and you have the customer side on top of the
direct connect connection where you can establish the IPsec VPN tunnels.
Apart from that, you can also integrate and segment the overall sd-wan in case if you have this within
your environment.
So in such cases you have to make use of the connect attachments.
So here you have the transit Gateway, Direct Connect, Gateway, Direct Connect and the customer side,
and you have the tunnel that has been established.
And this in turn allows you to segment your sd-wan traffic to a bus.
Now the connect attachment must be present.
As we know, Connect is used for BGP.
And so at the transit gateway level, you need to have the connect attachment here.
So these are some of the high level architectures specifically related to the direct connect with transit
gateways.
So with this will conclude today's video.
