Configuring IP parameters

• Manual tunnels provide static point-point connectivty
NOTE
IPV6 over IPV4 tunnel will not work when used with transperant VLAN flooding mode .
FIGURE 8 Manually configured tunnel
To configure a manual IPv6 tunnel, enter commands such as the following on a Layer 3 Switch
running both IPv4 and IPv6 protocol stacks on each end of the tunnel.
BigIron RX(config)# interface tunnel 1
BigIron RX(config-tnif-1)#tunnel source ethernet 3/1
BigIron RX(config-tnif-1)#tunnel destination 198.162.100.1
BigIron RX(config-tnif-1)#tunnel mode ipv6ip
BigIron RX(config-tnif-1)#ipv6 address 2001:b78:384d:34::/64 eui-64
This example creates tunnel interface 1 and assigns a global IPv6 address with an automatically
computed EUI-64 interface ID to it. The IPv4 address assigned to Ethernet interface 3/1 is used as
the tunnel source, while the IPv4 address 192.168.100.1 is configured as the tunnel destination.
Finally, the tunnel mode is specified as a manual IPv6 tunnel.
Syntax: interface tunnel <number>
For the <number> parameter, specify a value between 1 – 32.
Syntax: ipv6 address <ipv6-prefix>/<prefix-length> [eui-64]
You must specify the <ipv6-prefix> parameter in hexadecimal using 16-bit values between colons
as documented in RFC 2373.
You must specify the <prefix-length> parameter as a decimal value. A slash mark (/) must follow
the <ipv6-prefix> parameter and keyword configures the global or site-local address with an EUI-64
interface ID in the low-order 64 bits. The interface ID is automatically constructed in IEEE EUI-64
format using the interface’s MAC address.
Syntax: tunnel source <ipv4-address> | ethernet <port> | loopback <number> | ve <number>
You must specify the <ipv4-address> parameter using 8-bit values in dotted decimal notation.
The ethernet | loopback | ve parameter specifies an interface as the tunnel source. If you specify
an Ethernet interface, also specify the port number associated with the interface. If you specify a
loopback, VE, or interface, also specify the loopback, VE, or number, respectively.
Syntax: tunnel destination <ipv4-address>
You must specify the <ipv4-address> parameter using 8-bit values in dotted decimal notation.
Syntax: tunnel mode ipv6ip
