To configure a specific maximum transmission unit (MTU) value for IPSec tunnels, include the tunnel-mtu statement at the [edit services ipsec-vpn rule rule-name term term-name then] hierarchy level:
-
tunnel-mtu bytes;
![]() |
Note: The tunnel-mtu setting is the only place you need to configure an MTU value for IPSec tunnels. Inclusion of an mtu setting at the [edit interfaces sp-fpc/pic/port unit logical-unit-number family inet] hierarchy level is not supported. |
