Fig 22-2MRPP typical configuration scenario 1
The above topology often occurs on using MRPP protocol. The multi switch
constitutes a single WAPS ring, all of the switches only are configured an MRPP ring,
thereby constitutes a single MRPP ring.
In above configuration, SWITCH A configuration is primary node of MRPP ring, and
configures E1/1 to primary port, E1/2 to secondary port. Other switches are secondary
nodes of MRPP ring, configures primary port and secondary port separately.
To avoid ring, it should temporarily disable one of the ports of primary node, when it
enables each MRPP ring in the whole MRPP ring; and after all of the nodes are
configured, open the port.
When disable MRPP ring, it needs to insure the MRPP ting doesn’t have ring.
SWITCH A configuration Task Sequence:
Switch(Config)#MRPP enable
Switch(Config)#MRPP ring 4000
Switch(MRPP-ring-4000)#control-vlan 4000
Switch(MRPP-ring-4000)#primary-port Ethernet 1/1
Switch(MRPP-ring-4000)#secondary-port Ethernet 1/2
Switch(MRPP-ring-4000)#fail-timer 18
Switch(MRPP-ring-4000)#hello-timer 5
Switch(MRPP-ring-4000)#node-mode master
Switch(MRPP-ring-4000)#enable
Switch(MRPP-ring-4000)#exit
Switch(Config)#
SWITCH B configuration Task Sequence:
Switch(Config)#MRPP enable
