IPv6 Configuration Guide K/KA/KB.15.15

Configures the IPv4 or IPv6 address of the remote end of the tunnel. Must not be
the same address as the tunnel source. Tunnel mode must be configured before
tunnel destination.
Example 180 Configuring Destination and Source Addresses
HP Switch(tunnel-3)# tunnel source 20.30.30.3
HP Switch(tunnel-3)# tunnel destination 10.20.20.2
Configuring the Static MTU
Only the static tunnel MTU option is supported. Enter this command in tunnel context.
NOTE: The MTU value should be the same for the source and the destination switch.
Syntax
[no] tunnel mtu [ 1280 - 9198 ]
Configures the static MTU for the tunnel.
Default: 1280
Example 181 Configuring a Static MTU
HP Switch(tunnel-3)# tunnel mtu 1500
Configuring a Value for TOS
To configure a value to use for the TOS byte in the encapsulating IPv4 header when encapsulating
a packet to send over the tunnel interface, enter this command in tunnel context. If no value is
specified, the value of the TOS byte is determined from the traffic class field of the IPv6 header.
Syntax
[no] tunnel tos [ 0 - 63 | copy | use-qos ]
Configures a value to use for the TOS byte.
0 - 63
Range of static values.
copy
The TOS bits are copied from the IPv6 header. This is the default.
use-qos
Use the value returned by the QoS classifier.
Example 182 Configuring a TTL for the Packet
HP Switch(tunnel-3)# tunnel tos use-qos
Configuring a Value for Time-to-Live (TTL)
Use this command to configure the TTL in the encapsulating IPv4 header when encapsulating a
packet to send over the tunnel. Enter this command in tunnel context.
Syntax
[no] tunnel ttl [ 0 - 255 | copy ]
Configures the time-to-live.
