Opened: Aug 10, 2020
Severity: 3-Major

Symptoms

Network flows are reset and errors are found in /var/log/ltm: Route domain not reachable (strict mode).

Impact

Traffic is not sent to the node that is in a route domain. The iRule 'node' method and/or LTM policy 'node' specification require a route_domain to be specified in order for the traffic to be sent to a node that is assigned to a route domain.

Conditions

This might happen in either of the following scenarios: Scenario 1 ========== -- LTM with iRules configured. -- The iRule directs traffic to a node that is in a route domain. Scenario 2 ========== -- LTM with an LTM policy configured. -- The policy directs traffic to a node that is in a route domain.

Workaround

Specify the node along with Route domain ID. -- For iRules, change from this: when HTTP_REQUEST { node 10.10.10.10 80 } To this (assuming route domain 1): when HTTP_REQUEST { node 10.10.10.10%1 80 } -- For LTM policies, change from this: actions { 0 { forward select node 10.2.35.20 } } To this (assuming route domain 1): actions { 0 { forward select node 10.2.35.20%1 } }

Fix Information
