Configuring a destination address for a tunnel interface
To configure a destination address for a specific tunnel interface, enter the following command.
Brocade(config)# interface tunnel 1
Brocade(config-tnif-1)tunnel destination 10.108.5.2
Syntax: [no] tunnel destination ip-address
The ip-address variable is destination IP address being configured for the specified tunnel.
Configuring a tunnel interface for IPv6 encapsulation
To configure a specified tunnel interface for IPv6 encapsulation, enter the following command.
Brocade(config)# interface tunnel 1
Brocade(config-tnif-1)tunnel mode ipv6ip
Syntax: [no] tunnel mode ipv6ip 6to4 | auto-tunnel
The 6to4 parameter specifies automatic tunneling using 6 to 4.
The auto-tunnel parameter specifies automatic tunnel using IPv4 compatible ipv6 address.
Configuring an IP address for a tunnel interface
To configure an IP address for a specified tunnel interface, enter the following command.
Brocade(config)# interface tunnel 1
Brocade(config-tnif-1)ipv6 address 2001:0a0a:0a01::1/64
Syntax: [no] ipv6 address ipv6-address
The ipv6-address variable is the IPv6 address being configured for the specified tunnel interface.
Configuring a TTL value
This is an optional parameter that allows you to set the Time-to-Live value for the outer IP header of
the IPv6 tunnel packets.
To configure the TTL value, enter the following command.
Brocade(config)# interface tunnel 1
Brocade(config-tnif-1)tunnel ttl 100
Syntax: [no] tunnel ttl ttl-value
The ttl-value variable specifies a TTL value for the outer IP header. Possible values are 1 - 255. The
default value is 255.
Configuring a TOS value
This is an optional parameter that allows you to set the TOS value for the outer IP header of the
GRE tunnel packets.
To configure the TOS value, enter the following command.
Brocade(config)# interface tunnel 1
Brocade(config-tnif-1)tunnel tos 100
Syntax: [no] tunnel ttl tos-value
