Particular protocols are not being passed through to another segment. Thoroughly check the router's software and hardware configuration, as related to the router's protocol routing table. Are any incorrect configuration parameters present in the router's protocol routing table, as related to the specific protocol not properly being passed through to the destination segment? Take the necessary action to resolve the problem and retest the router for proper operation. If the failure symptom is gone, record the problem in the network maintenance and service log. If the problem still exists after retesting, go to the next step. Attempt to run router diagnostics. Did running the diagnostics produce any errors that identify a router failure? Take the necessary action to resolve the problem and retest the router for proper operation. If the failure symptom is gone, record the problem in the network maintenance and service log. If the problem still exists after retesting, go to the next step. A configuration problem may still exist with the router, but to get more conclusive fault-isolation data, run a protocol analysis session. When running a protocol analysis session on the segments involved in the router transfer, keep in mind that a router's main purpose is to connect Ethernet segments that need to share the same protocols; they must understand and be configured for the protocol that they are forwarding. If after performing the protocol analysis you cannot conclusively locate the problem, and you continue to find failure symptoms that point to a router problem, refer to the manufacturer's instructions.
