61.3.2 ULPP Typical Example2
Figure 4-4 ULPP typical example2
ULPP can implement the VLAN-based load balance. As the picture illustrated, SwitchA configures two ULPP
groups: port E1/1 is the master port and port 1/2 is the slave port in group1, port 1/2 is the master port and
port 1/1 is the slave port in group2. The VLANs protected by group1 are 1-100 and by group2 are 101-200.
Here both port E1/1 and port E1/2 at the forwarding state, the master port and the slave port mutually backup,
respectively forward the packets of different VLAN ranges. When port E1/1 has the problem, the traffic of
VLAN 1-200 are forwarded by port E1/2. When port E1/1 is recovering the normal state, still port E1/2
forwards the data of VLAN 101-200, the data of VLAN 1-100 are switched to port E1/1 to forward.
SwitchA configuration task list:
Switch(Config)#spanning-tree mst configuration
Switch(Config-Mstp-Region)#instance 1 vlan 1-100
Switch(Config-Mstp-Region)#instance 2 vlan 101-200
Switch(Config-Mstp-Region)#exit
Switch(Config)#ulpp group 1
Switch(ulpp-group-1)#protect vlan-reference-instance 1
Switch(ulpp-group-1)#exit
Switch(Config)#ulpp group 2
