Using the EE connectivity test to verify multipath routing
In "EE connectivity test with multipath routing enabled", the operator on HostA verifies the Enterprise Extender multipath routing environment by performing the following EE connectivity test:

IST2139I CONNECTIVITY TEST INFORMATION DISPLAYED FOR 2 OF 2 ROUTES
IST314I ENDThis example clearly shows that connectivity from HostA to HostB over the OSA1 interface does not exist. The router with IP address 9.67.1.21 is returning an ICMP message to the LDLC probe, which indicates the destination host is unreachable. For this case, investigate this router to determine why it returned this type of ICMP message.
The output also indicates that connectivity from HostA to HostB over the OSA2 interface does exist. Message IST2137I indicates that the route is a 5-hop configuration to the partner host. The display also shows that there are different routes through the IP network to the EE partner. When routing over the OSA2 interface, all five EE ports have successfully contacted the partner HostB with excellent round-trip times (RTT.)
