Bridging
The 6SSRM-02 provides the following types of high-speed bridging:
• Address-based bridging – The 6SSRM-02 performs this type of bridging by looking up the
destination address in an L2 lookup table on the line card that receives the bridge packet from
the network. The L2 lookup table indicates the exit port(s) for the bridged packet. If the packet
is addressed to the 6SSRM-02’s own MAC address, the packet is routed rather than bridged.
