346 CHAPTER 16: NETWORK-LAYER BRIDGING
The system supports network-layer bridging within a single chassis where
egress ports within the chassis share an IP address. It also supports
network-layer bridging within a cluster where egress ports on modules that
reside in different chassis can share an IP address. In this way, the layer 3
bridge can span across a single chassis, or multiple chassis in the same
cluster.
If for any reason you would like to assign the same IP address for non-cable
interfaces, note that you can also add Ethernet and Gigabit Ethernet
interfaces to bridge groups.
POS interfaces cannot be added to a network-layer bridge.
You can only assign 1 IP address to a specified bridge group.
A single egress port can belong to a maximum of 16 different NLBGs. An
NLBG can contain up to 32 physical interfaces; you can define a maximum of
16 NLBGs on single chassis.
