What is a BDI interface Cisco?

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.

What is meant by and the purpose of bridged virtual interface BVI on the access point?

Description. The Bridge-Group Virtual Interface (BVI) becomes available on routers when the bridge irb command has been given. This interface allows the router to route and bridge the same protocol over the same interface. The bridge group-number must match the bridge group defined for the bridge.

What is IRB Cisco?

IRB stands for Integrated Routing and Bridging. Like CRB (Concurrent Routing and Bridging), IRB allows a router to both route and bridge a single protocol. However, unlike CRB, IRB allows the routed and bridged interfaces to communicate with each other. See also interface bvi .

Do you need BDI interface configuration on ASR?

BDI interface configuration on ASR is not required if the motive is to just establish connectivity between the two switches. ! BGL.Q.16-3500-1#ping 10.1.1.3 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 10.1.1.3, timeout is 2 seconds: !!!!! Note: If you want to route outside of the ASR, BDI interface configuration is required.

How are bridge domain interfaces assigned in Cisco ASR 1000?

All the bridge domain interfaces on the Cisco ASR 1000 chassis share a common MAC address. The first bridge domain interface on a bridge domain is allocated a MAC address. Thereafter, the same MAC address is assigned to all the bridge domain interfaces that are created in that bridge domain.

Do You need A BDI interface for fa0 / 1?

A) Fa0/1 on both the switches are Layer-3 interfaces and are in the same broadcast domain. BDI interface configuration on ASR is not required if the motive is to just establish connectivity between the two switches. ! BGL.Q.16-3500-1#ping 10.1.1.3

What does BVI / BDI mean in virtual LAN?

In this scenario, BVI/BDI interface would act as the routed interface for those two bridged physical interfaces. All the packets coming in or going out of these bridged interfaces will have to pass through the BVI/BDI interface. Concept of Virtual Lans. The information in this document is based on ISR router (for BVI) and ASR1K (for BDI).
