+Nexthop Groups
+==============
+
+Nexthop groups are a way to encapsulate ECMP information together.  It's a
+listing of ECMP nexthops used to forward packets.
+
+.. clicmd:: nexthop-group NAME
+
+   Create a nexthop-group with an associated NAME.  This will put you into a
+   sub-mode where you can specify individual nexthops.  To exit this mode type
+   exit or end as per normal conventions for leaving a sub-mode.
+
+.. clicmd:: nexthop [A.B.C.D|X:X::X:XX] [interface [onlink]] [nexthop-vrf NAME] [label LABELS]
+
+   Create a v4 or v6 nexthop.  All normal rules for creating nexthops that you
+   are used to are allowed here.  The syntax was intentionally kept the same as
+   creating nexthops as you would for static routes.
+
+.. clicmd:: resilient buckets (1-256) idle-timer (1-4294967295) unbalanced-timer (1-4294967295)
+
+   Create a resilient Nexthop Group with the specified number of buckets, and
+   associated timers.  Instead of using the normal kernel hashing methodology
+   this specifies that X buckets will be created for the nexthop group and
+   when a nexthop is lost the buckets forwarding that particular nexthop
+   will be automatically re-assigned.  This cli command must be the first
+   command entered currently.  Additionally this command only works with linux 5.19
+   kernels or newer.
