What Is A Vpc Domain

Therefore cisco recommends that you create each vpc domain within the contiguous layer 2 network with a unique domain id.

What is a vpc domain. Subnet a range of ip addresses in your vpc. Virtual private cloud vpc a virtual network dedicated to your aws account. Vpc domain is composed of two peer devices.

This may also use the management ports. Connecting through existing layer 3 infrastructure such as an out of band management network. However the devices use the vpc system mac addresses only for link scope operations such as lacp.

A virtual private cloud vpc is a virtual network dedicated to your aws account. Each switch is connected via the vpc peer link. A vpc provides the following benefits.

You can have only one vpc domain id on each device. In case a peer device fails the other peer device will absorb all the traffic with minimal convergence time impact. Each peer device processes half of the traffic coming from the access layer.

Vpc domain includes the vpc peers keepalive links and the port channels that use the vpc technology. Vpc member port ports included within the vpcs. A single link between the switches between the management ports.

Each peer device in the vpc domain runs its own control plane and both devices work independently. Vpc master sticky bit is a programmed protection mechanism introduced to avoid unnecessary role change which would potentially be causing disruption on the network when the primary switch gets reloaded unexpectedly. You can launch your aws resources such as amazon ec2 instances into your vpc.
