In mostĬases, this will result in the use of smaller packets than necessary,īecause most paths have a PMTU greater than the IPv6 minimum link MTU defined in as the maximum packet size. Nodes not implementing Path MTU Discovery use the IPv6 minimum link ROM) may choose to omit implementation of Path MTU Discovery. A minimal IPv6 implementation (e.g., in a boot IPv6 nodes SHOULD implement Path MTU Discovery in order to discoverĪnd take advantage of paths with PMTU greater than the IPv6 minimum IPv6 defines a standard mechanism for a node to discover the (PMTU), and it is equal to the minimum link MTU of all the links in a This packet size is referred to as the Path MTU Successfully traverse the path from the source node to theĭestination node. Usually preferable that these packets be of the largest size that can

Node, the data is transmitted in a series of IPv6 packets. When one IPv6 node has a large amount of data to send to another RFC 1981 Path MTU Discovery for IPv6 August 1996 1. 15 McCann, Deering & Mogul Standards Track Largely derived from RFC 1191, which describes Path MTU Discovery forġ.
