DESCRIPTION short_description: Finds Path MTU (PMTU) from Cisco IOS network devices description:
- Tests reachability using ping from Cisco IOS device to a remote destination.
- To find path MTU the binary search algorithm is used.
- The range of search of PMTU is between ( max_size - max_range) and ( max_size ). author:

EXAMPLES
-
name: Test reachability to 10.10.10.10 using default vrf cisco.ios.ios_pmtu: dest: 10.10.10.10
-
name: Test reachability to 10.20.20.20 using NOC vrf cisco.ios.ios_pmtu: dest: 10.20.20.20 vrf: NOC
-
name: Test reachability to 10.40.40.40 using NOC vrf and setting source cisco.ios.ios_pmtu: dest: 10.40.40.40 source: Loopback 0 vrf: NOC
RETURN pmtu: description: Show the pmtu. returned: always type: int sample: 1600
