+# TE-9.1: FIB FAILURE DUE TO HARDWARE RESOURCE EXHAUST
+
+## Summary
+
+Validate gRIBI FIB_FAILED functionality.
+
+## Procedure
+
+*   Connect ATE port-1 to DUT port-1, and ATE port-2 to DUT port-2.
+
+*   Establish a gRIBI connection (SINGLE_PRIMARY and PRESERVE mode) to the DUT.
+
+*   Establish BGP session between ATE Port1 --- DUT Port1. Inject unique BGP routes to exhaust FIB on DUT.
+
+*   Continuously injecting the following gRIB structure until FIB FAILED is received. 
+    Each DstIP and VIP should be unique and of /32. All the NHG and NH should be unique (of unique ID).
+    DstIP/32 -> NHG -> NH {next-hop:} -> VIP/32 -> NHG -> NH {next-hop: AtePort2Ip}
+
+*   Expect FIB_PROGRAMMED message until the first FIB_FAILED message received.
+
+*   Validate that traffic for the FIB_FAILED route will not get forwarded. 
+
+*   Pick any route that received FIB_PROGRAMMED. Validate that traffic hitting the route should be forwarded to port2
