Release Information

Statement introduced in JUNOS Release 10.0.

Description

Maximum transmission unit (MTU) size for IPsec tunnels. This statement is useful for dynamic endpoint tunnels for which you cannot configure the tunnel-mtu statement at the [edit services ipsec-vpn rule rule-name term term-name then] hierarchy level.

For static IPsec tunnels, this statement sets the tunnel MTU value for all the tunnels within this service set. If you need a specific value for a particular tunnel, then set the tunnel-mtu statement at the [edit services ipsec-vpn rule rule-name term term-name then] hierarchy level.

Note: The tunnel-mtu setting at the [edit services ipsec-vpn rule rule-name term term-name then] hierarchy level overrides the value specified at the [edit services service-set service-set-name ipsec-vpn-options] hierarchy level.

Default: 1500 bytes
