msti 2 {

vlan200; # This VLAN corresponds to MSTP instance 2

}

Configure MSTP on Router 3:

[edit]

protocols {

mstp {

configuration-name mstp-for-R1-2-3; # The names must match to be in the same

region

revision-level 3; # The revision levels must match

interface ae2;

interface ae3;

msti 1 {

vlan100; # This VLAN corresponds to MSTP instance 1

}

msti 2 {

vlan200; # This VLAN corresponds to MSTP instance 2

bridge-priority 4096; # This bridge acts as VLAN 200 designated bridge on

# the R2-R3 segment

}

As a result of this configuration, VLAN 100 and VLAN 200 share physical links, but have

different designated ports, root ports, and alternate ports on the three different routers.

The designated, root, and alternate ports for the two VLANs on the three routers are

shown in Figure 6 on page 34.
