 Konfigurasi ini adalah contoh dari IRB. Konfigurasi ini memungkinkan IP bridging antara dua antarmuka Ethernet, dan routing IP dari antarmuka bridged menggunakan Bridged Virtual Interface (BVI). Dalam diagram jaringan berikut, ketika PC_A mencoba menghubungi PC_B, router R1 mendeteksi bahwa alamat IP tujuan (PC_B) berada di subnet yang sama, sehingga paket-paket tersebut dijembatani oleh router R1 antara antarmuka E0 dan E1. Ketika PC_A atau PC_B mencoba menghubungi PC_C, router R1 mendeteksi bahwa alamat IP tujuan (PC_C) berada dalam subnet yang berbeda, dan paket tersebut dialihkan menggunakan BVI. Dengan cara ini, protokol IP dijembatani serta dirutekan pada router yang sama.

-This configuration is an example of IRB. The configuration allows bridging IP between two Ethernet interfaces, and routing IP from bridged interfaces using a Bridged Virtual Interface (BVI). In the following network diagram, when PC_A attempts to contact PC_B, the router R1 detects that the destination's (PC_B) IP address is in the same subnet, so the packets are bridged by router R1 between interface E0 and E1. When PC_A or PC_B attempt to contact PC_C, the router R1 detects that the destination's (PC_C) IP address is in a different subnet, and the packet is routed using the BVI. This way, IP protocol is bridged as well as routed on the same router.

-The need to readdress IP end stations during moves can be avoided by bridging IP on some or all interfaces in the router connecting the VLANs. However, this eliminates all of the benefits of building router-based networks to control broadcasts at the network layer. Figure III shows what changes occur when the router is configured for bridging IP. Figure IV shows what happens when the router is configured for bridging IP with IRB.
+Gambar III menunjukkan bahwa router sekarang menjembatani IP. Kedua PC sekarang berada di subnet yang sama.

+Catatan: Router (bridge) sekarang meneruskan header layer MAC ke interface outward. Router masih mengakhiri header VLAN dan menerapkan header baru sebelum mengirim frame ke PC B.
-Note: The router (bridge) now forwards the MAC layer header across to the outward-bound interface. The router still terminates the VLAN header and applies a new header prior to sending the frame out to PC B.
