If Switch 2 includes dual Routing Engines, configure NSB. To quickly configure nonstop
bridging on Switch 2, copy the following commands and paste them into the switch
terminal window:
set chassis redundancy graceful switchover
set system commit synchronize
set protocols layer2-control nonstop-bridging
To configure RSTP and nonstop bridging on Switch 2:
Configure the VLANs
1.
[edit vlans]
user@switch2# set voice-vlan description "Voice VLAN"
user@switch2# set voice-vlan vlan-id 10
user@switch2# set employee-vlan description "Employee VLAN"
user@switch2# set employee-vlan vlan-id 20
user@switch2# set guest-vlan description "Guest VLAN"
user@switch2# set guest-vlan vlan-id 30
user@switch2# set camera-vlan vlan-description "Camera VLAN"
user@switch2# set camera-vlan vlan-id 40
Configure the VLANs on the interfaces, including support for the Ethernet switching
2.
protocol:
[edit interfaces]
user@switch2# set ge-0/0/14 unit 0 family ethernet-switching vlan members [10 20 30
40]
user@switch2# set ge-0/0/18 unit 0 family ethernet-switching vlan members [10 20 30
40]
Configure the port mode for the interfaces:
3.
[edit interfaces]
user@switch2# set ge-0/0/14 unit 0 family ethernet-switching interface-mode trunk
user@switch2# set ge-0/0/18 unit 0 family ethernet-switching interface-mode trunk
Configure RSTP on the switch:
4.
[edit protocols]
user@switch2# rstp bridge-priority 32k
user@switch2# rstp interface ge-0/0/14 cost 1000
user@switch2# rstp interface ge-0/0/14 mode point-to-point
user@switch2# rstp interface ge-0/0/18 cost 1000
user@switch2# rstp interface ge-0/0/18 mode point-to-point
If Switch 2 includes dual Routing Engines, configure nonstop bridging. To configure NSB
on Switch 2:
Enable graceful Routing Engine switchover (GRES):
1.
[edit chassis redundancy]
user@switch2# set graceful-switchover
, ,
voice-vlan employee-vlan
, and
guest-vlan camera-vlan
