Figure 10: Spanning Tree IGMP Fast Recovery Configuration Example
Configuration of Switch 1:
1. Enable the MSTP protocol:
Switch1#
configure terminal
Switch1(config)#
protocol
Switch1(cfg protocol)#
mstp enable
2. Set the bridge priority for MST instance 0 to zero:
Switch1(cfg protocol)#
mstp 0 priority 0
3. Enable the Spanning tree IGMP fast recovery:
Switch1(cfg protocol)#
spanning-tree igmp-fast-recovery
Switch1(cfg protocol)#
exit
4. Set port 1/1/8 as an edge port:
Switch1(config)#
interface 1/1/8
Switch1(config-if 1/1/8)#
mstp edge-port
Switch1(config-if 1/1/8)#
exit
5. Enable IGMP snooping and set interfaces 1/1/1 and 1/1/2 as mrouter ports:
Switch1(config)#
ip igmp snooping
Switch1(config)#
ip igmp snooping vlan 1 mrouter interface 1/1/1
Switch1(config)#
ip igmp snooping vlan 1 mrouter interface 1/1/2
Configuration of Switch 2:
1. Enable the MSTP Protocol:
Switch2#
configure terminal
Switch2(config)#
protocol
Switch2(cfg protocol)#
mstp enable
2. Enable MSTP Fast Ring for accelerating its operation in ring topology:
