Configuring the JUNOS Software for IPv6 Path MTU Discovery

By default, path MTU (PMTU) discovery for IPv6 packets is enabled. To disable IPv6 PMTU discovery, include the no-ipv6-path-mtu-discovery statement at the [edit system internet-options] hierarchy level:

[edit system internet-options] no-ipv6-path-mtu-discovery;

To configure IPv6 PMTU discovery timeout in minutes, include the ipv6-path-mtu-discovery-timeout statement at the [edit system internet-options] hierarchy level:

[edit system internet-options] ipv6-path-mtu-discovery-timeout minutes;

For details about IPv6 PMTU, see RFC 1981, Path MTU Discovery for IP version 6.
