Now configure VLAN 4. Remember this is a flat segment that, in the previous example, obtained its
IP default gateway and IPX router services from an external device. In this example, device-A will
provide the routing services for VLAN 4. You also want to configure the STP priority for VLAN 4 to
make device-A the root bridge for this VLAN.
PowerConnect-A(config-vif-4)# vlan 4 name Bridged_ALL_Protocols
PowerConnect-A(config-vlan-4)# untagged ethernet 17 to 24
PowerConnect-A(config-vlan-4)# tagged ethernet 25 to 26
PowerConnect-A(config-vlan-4)# spanning-tree
PowerConnect-A(config-vlan-4)# spanning-tree priority 500
PowerConnect-A(config-vlan-4)# router-interface ve5
PowerConnect-A(config-vlan-4)# interface ve5
PowerConnect-A(config-vif-5)# ip address 1.1.3.1/24
PowerConnect-A(config-vif-5)# ip ospf area 0.0.0.0
PowerConnect-A(config-vif-5)# ipx network 3 ethernet_802.3
PowerConnect-A(config-vif-5)#
It is time to configure a separate port-based VLAN for each of the routed backbone ports (Ethernet
25 and 26).
If you do not create a separate tagged port-based VLAN for each point-to-point backbone link, you
need to include tagged interfaces for Ethernet 25 and 26 within VLANs 2, 3, and 8. This type of
configuration makes the entire backbone a single STP domain for each VLAN 2, 3, and 8. This is
the configuration used in the example in “Configuring IP subnet, IPX network and protocol-based
VLANs” on page 452. In this scenario, the virtual routing interfaces within port-based VLANs 2, 3,
and 8 will be accessible using only one path through the network. The path that is blocked by STP is
not available to the routing protocols until it is in the STP FORWARDING state.
PowerConnect-A(config-vif-5)# vlan 5 name Rtr_BB_to_Bldg.2
PowerConnect-A(config-vlan-5)# tagged ethernet 25
PowerConnect-A(config-vlan-5)# no spanning-tree
PowerConnect-A(config-vlan-5)# router-interface ve6
PowerConnect-A(config-vlan-5)# vlan 6 name Rtr_BB_to_Bldg.3
PowerConnect-A(config-vlan-6)# tagged ethernet 26
PowerConnect-A(config-vlan-6)# no spanning-tree
PowerConnect-A(config-vlan-6)# router-interface ve7
PowerConnect-A(config-vlan-6)# interface ve6
PowerConnect-A(config-vif-6)# ip addr 1.1.4.1/24
PowerConnect-A(config-vif-6)# ip ospf area 0.0.0.0
PowerConnect-A(config-vif-6)# ipx network 4 ethernet_802.3
PowerConnect-A(config-vif-6)# interface ve7
PowerConnect-A(config-vif-7)# ip addr 1.1.5.1/24
