The show interface tunnel command displays the status and configuration information for a tunnel
interface as shown in the following.
BigIron RX# show interface tunnel 1
Tunnel1 is up, line protocol is up
Hardware is Tunnel
Tunnel source 63.148.1.2
Tunnel destination is 110.110.2.12
Tunnel mode gre ip
Tunnel loopback is 1/3
No port name
MTU 1476 Bytes
Syntax: show interface tunnel <number>
The <number> parameter indicates the tunnel interface number for which you want to display
information.
IPv6 over IPv4 tunnels in hardware
To enable communication between the isolated IPv6 domains using the IPv4 infrastructure, you
can configure IPv6 over IPv4 tunnels.
Brocade supports the following IPv6 over IPv4 tunneling in hardware mechanisms:
• Manually configured tunnels
In general, a manually configured tunnel establishes a permanent link between routers in IPv6
domains. A manually configured tunnel has explicitly configured IPv4 addresses for the tunnel
source and destination.
This tunneling mechanism requires that the router at each end of the tunnel run both IPv4 and IPv6
protocol stacks. The routers running both protocol stacks, or dual-stack routers, can interoperate
directly with both IPv4 and IPv6 end systems and routers.
Configuring a manual IPv6 tunnel
You can use a manually configured tunnel to connect two isolated IPv6 domains. You should deploy
this point-to-point tunnel mechanism if you need a permanent and stable connection.
Configuration notes
• The tunnel mode should be ipv6ip indicating that this is ipv6 manual tunnel
• Both source and destination addresses needs to be configured on the tunnel.
• On the remote side we need to have exactly opposite source or destination pair.
• The tunnel destination should be reachable through the ipv4 backbone.
• The ipv6 address on the tunnel needs to be configured for the tunnel to come up
• Both static and dynamic IPv6 routing protocols on top of the tunnel are supported
• The tunnel source can be ip address or interface name
