What is bridge domain in Cisco router?
Bridge domain interface is a logical interface that allows bidirectional flow of traffic between a Layer 2 bridged network and a Layer 3 routed network traffic. Bridge domain interfaces are identified by the same index as the bridge domain.
How do I setup a domain bridge?
Configuring a Bridge Domain
- For the vlan-id statement, you can specify either a valid VLAN identifier or the none or all options.
- To include one or more logical interfaces in the bridge domain, specify an interface-name for an Ethernet interface you configured at the [edit interfaces] hierarchy level.
What is BVI in Cisco?
A BVI (Bridge Group Virtual Interface) is a routed interface that represents a set of interfaces that gets bridged.
What is a bridge group Cisco?
The bridge-group command is used to configure a Cisco device to bridge traffic between two interfaces. In your configuration above traffic is being bridged between physical ethernet interfaces and tunnel interfaces.
What is the difference between bridge domain and VLAN?
Bridge groups provide a method to group two or more ports into a single broadcast domain, where as VLAN provide a method to group many ports into a single broadcast domain or establish a number of broadcast domains (or secure groups) on a single switch.
What is domain in ACI?
The physical domain in ACI defines a pool of resources that ACI can be leverage to communicate to an external physical domain. Customers can leverage this method to connect Layer 2 (VLAN) to an external switch. This way they can migrate their workloads from existing networks into the ACI fabric.
How do I bridge two VLANs together?
The simplest way to enable routing between the two VLANs to simply connect an additional port from each VLAN into a Router. The Router doesn’t know that it has two connections to the same switch — nor does it need to. The Router operates like normal when routing packets between two networks.
What is the difference between VLAN and bridge?
What is a bridge domain in ACI?
A Bridge Domain (BD) is a Layer 2 representation inside the ACI fabric. The BD is where users will define their Anycast Gateway/subnet which would provide the default gateway for their host attached to the fabric.
Why do we need bridge domain?
In Junos OS Release 9.2 and later, bridge domains provide support for a Layer 2 trunk port. A Layer 2 trunk interface enables you to configure a single logical interface to represent multiple VLANs on a physical interface.
What is the difference between EVPN and VXLAN?
Ethernet VPNs (EVPNs) enable you to connect groups of dispersed customer sites using Layer 2 virtual bridges, and Virtual Extensible LANs (VXLANs) allow you to stretch Layer 2 connectivity over an intervening Layer 3 network, while providing network segmentation like a VLAN, but without the scaling limitation of …
What is tenant in ACI?
Cisco ACI Tenant. Overall, a tenant is a logical container for application policies and it includes one or more virtual routing and forwarding (VRF) instances or contexts which can be associated with multiple bridge domains. This concept is very similar to the Private VLAN which is being used in traditional networking.
What is Cisco ACI Aaep?
PASS:cisco. The Attachable Access Entity Profile (AAEP or AEP for short) is a construct of the ACI fabric that joins separate entity types. It is a critical policy object with associating a given domain type and VLAN pool with interface policy that will be used within tenant space.
Is a VLAN a bridge?
Every VLAN has an equivalent bridge. Most of the configuration required for bridging is related to the spanning-tree algorithm, which allows the connected network topology to contain multiple physical paths between two stations but constrains the active topology to a single-span tree.
