Command introduced before JunosE Release 7.1.0.
ip keyword made optional in JunosE Release 7.2.0.
Enables and configures path MTU discovery on the virtual router. Issuing the command
without any keywords enables path MTU discovery. Using the keywords with the command
configures specified values. The no version, when issued with a keyword, deletes the
value. When issued without any keywords, the no version disables path MTU discovery
on the virtual router.
ip—Optional keyword for use with older scripts
vrfName—Name of the VRF; string of 1–32 alphanumeric characters
indefinite—Disables aging functions. That is, TCP does not attempt to increase the
path MTU; the path MTU decreases only in response to received ICMP Too Big
messages.
minutes—Time (in minutes) that TCP waits after receiving an ICMP Too Big message
before attempting to increase the path MTU. The timer range is 1–30 minutes.
minutes_2—Time (in minutes) that TCP waits after a successful path MTU increase
before attempting to increase it again. The timer range is 1–30 minutes.
maxMtu—Maximum MTU size that the virtual router can accept; number, in the range
68–65535; default value is no limit
minMtu—Minimum MTU value that the virtual router can accept; number, in the range
68–65535; default value is no limit
blackHoleThreshold—Black hole threshold value that you want all connections on this
virtual router to use. The range is 0–65535.
