ipv6 mtu

This command sets the size of the maximum transmission unit (MTU) for
IPv6 packets sent on an interface. Use the no form to restore the default
setting.
Syntax
ipv6 mtu size
no ipv6 mtu
size - Specifies the MTU size. (Range: 1280-65535 bytes)
Default Setting
1500 bytes
Command Mode
Interface Configuration (VLAN)
Command Usage
• If a non-default value is configured, an MTU option is included in the
router advertisements sent from this device. This option is provided
to ensure that all nodes on a link use the same MTU value in cases
where the link MTU is not otherwise well known.
• IPv6 routers do not fragment IPv6 packets forwarded from other
routers. However, traffic originating from an end-station connected to
an IPv6 router may be fragmented.
• All devices on the same physical medium must use the same MTU in
order to operate correctly.
• IPv6 must be enabled on an interface before the MTU can be set.
Example
The following example sets the MTU for VLAN 1 to 1280 bytes:
Console(config)#interface vlan 1
Console(config-if)#ipv6 mtu 1280
Console(config-if)#
36-26
