Chapter 16 IPv6 Tunnel Configuration
Configuration Flow
The 6in4 tunnel is of v6 nature and thus IPv6 needs to be enabled. The source address
of the tunnel is the IPv4 address of the local router, whereas the destination address is
the IPv4 address of the peer router. There must be a route for interworking between the
source address and the destination address of the tunnel (via the IPv4 routing protocol,
the static routing protocol or other routing protocols).
1. Create 6in4 tunnel interfaces and enable IPv6 on them.
2. Enter the tunnel configuration mode from the global mode, and then enter the 6in4
tunnel interface to be configured.
3. Configure the tunnel mode, the source address, and the destination address.
