+## Summary
+
+IPv4/IPv6 unicast routes next hop group and next hop.
+
+## Testbed
+
+* atedut_4.testbed
+
+## Test Setup
+
+### Generate DUT and ATE Configuration
+
+Configure DUT:port1,port2,port3 for IS-IS session with ATE:port1,port2,port3
+*   IS-IS must be level 2 only with wide metric.
+*   IS-IS must be point to point.
+*   Send 1000 ipv4 and 1000 ipv6 IS-IS prefixes from ATE:port3 to DUT:port3.
+
+
+Establish eBGP sessions between ATE:port1,port2 and DUT:port1,port2 and another between ATE:port3 and DUT:port3.
+*   Configure eBGP over the interface ip.
+*   eBGP must be multipath.
+*   Advertise 1000 ipv4,ipv6 prefixes from ATE port1,port2 observe received prefixes at DUT.
+*   Validate total number of entries of AFT for IPv4 and IPv6.
+*   Each prefix must have 2 next hops pointing to ATE port1,port2.
+*   Advertise 100 ipv4,ipv6 from ATE port3 observe received prefixes at DUT.
+
+Establish RSVP Sessions between ATE:port3 and SUT:port3.
+*   Configure mpls and rsvp sessions.
+*   Configure 2 ingress TE tunnels from DUT:port3 to ATE:port3.
+*   Tunnel destination is interface ip of ATE:port3.
+*   Configure explicit null and ipv6 tunneling.
+*   BGP advertised routes from ATE:port3 must be pointing to the 2 tunnels in the DUT.
+
+### Procedure
+
+*   Use gNMI.Set with REPLACE option to push the Test Setup configuration to the DUT.
