Parameters

gre: Specifies the GRE over IPv4 tunnel mode.

gre ipv6: Specifies the GRE over IPv6 tunnel mode.

ipv4-ipv4: Specifies the IPv4 over IPv4 tunnel mode.

ipv4-ipv6: Specifies the IPv4 over IPv6 tunnel mode.

ipv6-ipv4: Specifies the IPv6 over IPv4 manual tunnel mode.

ipv6-ipv4 6to4: Specifies the IPv6 over IPv4 6to4 tunnel mode.

ipv6-ipv4 isatap: Specifies the IPv6 over IPv4 ISATAP tunnel mode.

ipv6-ipv6: Specifies the IPv6 over IPv6 tunnel mode.

Description

Use tunnel-protocol to specify the tunnel mode for the tunnel interface.

Use undo tunnel-protocol to restore the default.

The default tunnel is a GRE over IPv4 tunnel.

You can select a tunnel mode according to the actual network topology and application. The two ends of a tunnel must have the same tunnel mode specified. Otherwise, traffic transmission may fail.

Only one automatic tunnel can be created at the start point of a tunnel.

Examples

# Specify the 6to4 tunnel mode for interface Tunnel 2.
