After we set MTU to 9700, can not sync name table between two node, part of them will lost, and show the following error:
/*********************************/
no route to host
/*********************************/
If keep the MTU as default value, will not trigger this issue.
Not sure if this is TIPC limitation or PMTU defect
1, set one of node's MTU to 9700
2, config tipc on two node with tipc-config, such as:
tipc-config -addr=1.1.20552,tipc-config -be=eth:eth2.4901
3, then call tipc related API to try to do communication between two node.
issue will happen when one node try to send tipc message to another node:
