Fast Ethernet Subscriber Port, Frame Relay Trunk Example

The following example uses the Fast Ethernet subinterface as the subscriber port and Frame Relay as the trunk:

bridge 1 protocol ieee

#Form a subscriber bridge group using policy 1

bridge 1 subscriber-policy 1 bridge 1 protocol ieee

interface fast0.1 encapsulation isl 1

#Put fast0.1 into subscriber group 1

#

bridge-group 1 interface fast0.2 encapsulation isl 2

#

#put fast0.2 into subscriber group 1

bridge-group 1 interface serial0

encapsulation frame-relay int s0.1 point-to-point

#Use PVC 155 as the signal channel for setting up connections with the access-server

frame-relay interface-dlci 155

#Set the trunk to go upstream

#

bridge-group 1 trunk

ATM Subscriber Ports, ATM Trunk Example

The following example uses ATM subinterfaces as the subscriber ports and the ATM as the trunk:

bridge 1 protocol ieee

#

#Use subscriber policy 3

bridge 1 subscriber-policy 3

#Change the ARP behavior from permit to deny

subscriber-policy 3 arp deny

#Change the multicast from permit to deny

#

subscriber-policy 3 multicast deny
