怎么在交换机和bras上配ipsg动态绑定

BRAS配置：

dhcp server ip-pool gcableustb
 gateway-list 11.58.255.65 export-route
 network 11.58.255.64 mask 255.255.255.192
 address range 11.58.255.66 11.58.255.100
 dns-list 103.27.24.1 103.27.24.2

interface Ten-GigabitEthernet2/1/1.1100
 ip address 11.58.255.65 255.255.255.192
 vlan-type dot1q vid 1100
 ip subscriber l2-connected enable
 ip subscriber initiator dhcp enable
 ip subscriber initiator unclassified-ip enable matching-user
 ip subscriber initiator arp enable
 ip subscriber dhcp option60 match gcableustb
 ip subscriber user-detect ip icmp retry 2 interval 30
 ip subscriber unclassified-ip domain gcableustb
 ip subscriber trust option60

domain name gcableustb
 authorization-attribute ip-pool gcableustb
 authentication ipoe none
 authorization ipoe none
 accounting ipoe none
