MSTP configuration example
Network requirements
As shown in Figure 25:
• All devices on the network are in the same MST region. Router A and Router B work at the
distribution layer. Router C and Router D work at the access layer.
• Configure MSTP so that packets of different VLANs are forwarded along different spanning trees:
Packets of VLAN 10 are forwarded along MSTI 1, those of VLAN 30 are forwarded along MSTI 3,
those of VLAN 40 are forwarded along MSTI 4, and those of VLAN 20 are forwarded along MSTI
0.
• VLAN 10 and VLAN 30 are terminated on distribution layer devices, and VLAN 40 is terminated
on access layer devices. The root bridges of MSTI 1 and MSTI 3 are Router A and Router B,
respectively, and the root bridge of MSTI 4 is Router C.
