This section shows examples of manually configured tunnels between brouter ports and VLANs.
The following figure shows the tunnel configuration between brouter ports.
You must configure static routes, RIP, or OSPF on both the source (Switch 1) and destination (Switch 2) IPv4 interfaces to communicate on the IPv4 network. You must configure IPv4 addresses on the source and destination.
Configuring Switch 1
Create an IPv6 VLAN and add ports to the VLAN.
vlan create 10 type port-mstprstp 0 vlan mlt 10 4 vlan members 10 1/1 portmember interface vlan 10 ipv6 interface ipv6 interface enable ipv6 interface address 4000:0:0:0:0:0:0:1/64 exit
Create an IPv4 brouter port and enable OSPF on the port.
interface GigabitEthernet 1/30 brouter port 1/30 vlan 1000 subnet 172.21.80.1/255.255.255.0 mac-offset 6
Create the tunnel from the source to the destination.
ipv6 tunnel 1 source 172.21.80.1 address 2500:0000:0000:0000:0000:0000:0000:0001/64 destination 192.168.20.1
Configure a static route on the source.
ipv6 route 4000:0:0:0:0:0:0:2/64 cost 1 tunnel 1
Optionally, you can create an OSPFv3 interface through the tunnel.
router ospf ipv6-enable router ospf ipv6 tunnel 1 area 0.0.0.0 ipv6 tunnel 1 enable exit
Configuring Switch 2
Create an IPv6 VLAN and add ports to the VLAN.
vlan create 40 type port-mstprstp 0 vlan mlt 40 4 vlan members 40 1/2 portmember interface vlan 40 ipv6 interface ipv6 interface enable ipv6 interface address 4000:0:0:0:0:0:0:2/64 exit
Create an IPv4 brouter port and enable OSPF on the port.
interface GigabitEthernet 1/30 brouter port 1/30 vlan 2000 subnet 192.168.20.1/255.255.255.0 mac-offset 6
Create the tunnel from the destination to the source.
ipv6 tunnel 1 source 192.168.20.1 address 2500:0000:0000:0000:0000:0000:0000:0002/64 destination 172.21.80.1
Configure a static route on the destination.
ipv6 route 4000:0:0:0:0:0:0:1/64 cost 1 tunnel 1
Optionally, you can create an OSPFv3 interface through the tunnel.
router ospf ipv6-enable router ospf ipv6 tunnel 1 area 0.0.0.0 ipv6 tunnel 1 enable exit
The following figure shows the tunnel configuration between VLANs.
You must configure static routes, and either RIP or OSPF on both the source (Switch 1) and destination (Switch 2) IPv4 interfaces to communicate on the IPv4 network. You must configure IPv4 addresses on the VLANs.
Configuring Switch 1
Create an IPv6 VLAN and add ports to the VLAN.
vlan create 10 type port-mstprstp 0 vlan mlt 10 4 vlan members 10 1/1 portmember interface vlan 10 ipv6 interface ipv6 interface enable ipv6 interface address 4000:0:0:0:0:0:0:1/64 exit
Create an IPv4 VLAN, add ports to the VLAN, and enable OSPF on the VLAN.
vlan create 20 type port-mstprstp 0 vlan mlt 20 4 vlan members 20 1/30 portmember interface vlan 20 ip address 172.21.80.1 255.0.0.0 ip ospf enable exit
Create the tunnel from the source to the destination.
ipv6 tunnel 1 source 172.21.80.1 address 2500:0000:0000:0000:0000:0000:0000:0001/64 destination 192.168.20.1
Configuring Switch 2
Create an IPv6 VLAN and add ports to the VLAN.
vlan create 40 type port-mstprstp 0 vlan mlt 40 4 vlan members 40 1/2 portmember interface vlan 40 ipv6 interface ipv6 interface enable ipv6 interface address 4000:0:0:0:0:0:0:2/64 exit
Create an IPv4 VLAN , add ports to the VLAN, and enable OSPF on the VLAN.
vlan create 30 type port-mstprstp 0 vlan mlt 30 4 vlan members 30 1/30 portmember interface vlan 30 ip address 192.168.20.1 255.0.0.0 ip ospf enable exit
Create the tunnel from the destination to the source.
ipv6 tunnel 1 source 192.168.20.1 address 2500:0000:0000:0000:0000:0000:0000:0002/64 destination 172.21.80.1
Use the following show command to verify tunnel creation on the source device:
Switch:1(config)#show ipv6 tunnel 1 detail ================================================================================ Tunnel Interface Information ================================================================================ ID LOCAL ADDRESS REMOTE ADDRESS OPER STATUS TYPE -------------------------------------------------------------------------------- 1 172.21.80.1 192.168.20.1 active manual 1 out of 1 Total number of entries displayed. -------------------------------------------------------------------------------- ================================================================================ Address Information ================================================================================ IPV6 TYPE ORIGIN STATUS ADDRESS -------------------------------------------------------------------------------- 2500:0:0:0:0:0:0:1 UNICAST MANUAL PREFERRED fe80:0:0:0:0:0:ac15:5001 UNICAST LINKLAYER PREFERRED 2 out of 2 Total number of entries displayed.
Use the following show command to verify tunnel creation on the destination device:
