IPv4 and IPv6 Commands
Changing the MTU value (with the mtu interface configuration command) can affect the IPv6 MTU value.
Note
If the current IPv6 MTU value is the same as the MTU value, and you change the MTU value, the IPv6
MTU value will be modified automatically to match the new MTU. However, the reverse is not true;
changing the IPv6 MTU value has no effect on the value for the mtu command.

Examples
This example (not applicable for BNG) shows how to set the maximum IPv6 packet size for GigabitEthernet
interface 0/1/1/0 to 1350 bytes:
RP/0/RSP0/CPU0:router(config)# interface gigabitethernet 0/1/1/0
RP/0/RSP0/CPU0:router(config-if)# ipv6 mtu 1350
For BNG, this example shows how to set the maximum IPv6 packet size to 1350 bytes in the dynamic template
configuration mode:
RP/0/RSP0/CPU0:router(config)# dynamic-template type ppp foo
RP/0/RSP0/CPU0:router(config-dynamic-template-type)# ipv6 mtu 1350
