The ipv6 mtu would imposed a limit for transit traffic. For instance if the egress interface ipv6 mtu is lower than the ingress interface and received packet is too big to be forwarded out the egress interface, the router would discard the packet and send an ICMPv6 Packet Too Big (PTB) message to the source.

MTU test - LetMeCheck.it Online MTU test allows you to test the maximum MTU size from our host to your destination. To check your MTU, simply provide your IP or DNS hostname. We will test the PMTU (Path Maximum Transfer Unit) aka maximum MTU size (unfragmented) between our host and your destination, most likely the outside of your router or firewall.

IPv6 requires that every link in the internet have an MTU of 1280 octets or greater. On any link that cannot convey a 1280-octet packet in one piece, link-specific fragmentation and reassembly must be provided at a layer below IPv6. What is the minimum MTU size? - Network Engineering Stack

IPv6 nodes SHOULD implement Path MTU Discovery in order to discover and take advantage of paths with PMTU greater than the IPv6 minimum link MTU [IPv6-SPEC]. A minimal IPv6 implementation (e.g., in a boot ROM) may choose to omit implementation of Path MTU Discovery. IPv6 Datagram Size, Maximum Transmission Unit (MTU The most important differences between IPv4 and IPv6 with respect to datagram size, MTU, fragmentation and reassembly are: Increased Default MTU: In IPv4, the minimum MTU that routers and physical links were required to handle was 576 bytes. In IPv6, all links must handle a datagram size of at least 1280 bytes. IPv6 MTU Path Discovery - Cisco Nov 18, 2012 Change MTU size in Windows 10 - MyRandomTechBlog.com
