+--------------------------------------------------------------------------------
+* IOSXR
+    * Modified ShowVrfAllDetail:
+        * Modified regex <p4_1> to capture all interface names
+            * Replaced the previous regex that relied on specific interface prefixes (e.g., Gi, Bun, Ten, etc.) with a more general pattern.
+        * Introduced `in_interfaces_section` flag for accurate section tracking
