Configuring Bridging on the ML-Series Card

This chapter describes how to configure bridging for the ML-Series card. Bridging is one of the simplest configurations of the ML-Series card. Other alternatives exist to simple bridging, such as Integrated Routing and Bridging (IRB). The user should consult the chapter detailing their desired type of configuration.

This chapter includes the following major sections:

•Understanding Bridging, page 16-1

•Configuring Bridging, page 16-2

•Monitoring and Verifying Bridging, page 16-3

Caution Cisco Inter-Switch Link (ISL) and Cisco Dynamic Trunking Protocol (DTP) are not supported by the ML-Series cards, but the ML-Series broadcast forwards these formats. Using ISL or DTP on connecting devices is not recommended. Some Cisco devices attempt to use ISL or DTP by default.

Understanding Bridging

The ML-Series card supports transparent bridging for Fast Ethernet, Fast EtherChannel (FEC), packet-over-SONET/SDH (POS) ports, and POS channel. It supports a maximum of 255 active bridge groups. Transparent bridging combines the speed and protocol transparency of a spanning-tree bridge, along with the functionality, reliability, and security of a router.

To configure bridging, you must perform the following tasks in the modes indicated:

•In global configuration mode:

–Enable bridging of IP packets.

–(Optional) Select the type of Spanning Tree Protocol (STP).

•In interface configuration mode:

–Determine which interfaces belong to the same bridge group.

The ML-Series card bridges all nonrouted traffic among the network interfaces comprising the bridge group. If spanning tree is enabled, the interfaces become part of the same spanning tree. Interfaces that do not participate in a bridge group cannot forward bridged traffic.
