MSTP BPDU Guard の設定
この項では、MSTP BPDU Guard を設定する方法について説明します。
Router# configure
Router(config)# l2vpn bridge group bg1
Router(config-l2vpn-bg)# bridge-domain bd1
Router(config-l2vpn-bg-bd)# int TenGigE 0/0/0/7
Router(config-l2vpn-bg-bd-ac)# root
Router(config)# spanning-tree mst m0
Router(config-mstp)# interface tenGigE 0/0/0/7
Router(config-mstp-if)# portfast bpduguard
Router(config-mstp-if)# root
Router(config)# int tenGigE 0/0/0/7 l2transport
Router(config-if-l2)# commit
