+zebra Table Import
+==================
+
+Zebra supports importing an alternate routing table into the main unicast RIB (URIB).
+An imported table will continously sync all changes to the main URIB as routes are
+added or deleted from the alternate table.
+Zebra also supports importing into the main multicast RIB (MRIB) which can be used
+to affect how multicast RPF lookups are performed as described in :ref: `_pim-multicast-rib`.
+
+.. clicmd:: ip import-table (1-252) [mrib] [distance (1-255)] [route-map RMAP_NAME]
+
+   Import table, by given table id, into the main URIB (or MRIB). Optional distance can override
+   the default distance when importing routes from the alternate table. An optional route map
+   can be provided to filter routes that are imported into the main table.
