Spanning tree configuration example
NOTE:
In this configuration example, Device A, Device B, Device C, or Device D is the SecPath firewall.
Network requirements
As shown in Figure 57 , all devices on the network are in the same MST region. Device A and Device B
work at the distribution layer. Device C and Device 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 the distribution layer devices, and VLAN 40 is terminated on
the access layer devices, so the root bridges of MSTI 1 and MSTI 3 are Device A and Device B
respectively, and the root bridge of MSTI 4 is Device C.
