IPv6 Over IPv4 tunnels in hardware
19
• Tunnel Interface
• Source Address or Source Interface for the Tunnel
• Destination address for the Tunnel
• IPv6 Encapsulation
• IP address for the Tunnel
• TTL Value (optional)
• TOS Value (optional)
• MTU Value (optional)
NOTE
Do not forward packets from one type of tunnel to another type of tunnel in XPP. Packets may not be
routed properly.
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.
FIGURE 204 Manually configured tunnel
Configuration notes on manual tunnels:
• 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 you need to have exactly opposite source/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.
• The tunnel source can be an IP address or interface name.
• Manual tunnels provide static point-point connectivity.
• Static routing on top of the tunnel is supported.
• IPv6 routing protocols including OSPFv3 and RIPing on top of the tunnel are supported.
NOTE
IPv6 IS-IS is not supported on top of the tunnel.
