Procedure

Initial Setup:

• Connect DUT port-1, port-2 and port-3 to ATE port-1, port-2 and port-3 respectively
• Configure IPv4/IPv6 addresses on DUT and ATE the interfaces
• Configure one IPv4 destination i.e. ipv4-network = 203.0.113.0/24 connected to ATE port 1 and 2
• Configure one IPv6 destination i.e. ipv6-network = 2001:db8:128:128::/64 connected to ATE port 1 and 2

RT-1.26.1

Test to validate static route ECMP

• Configure IPv4 static routes:
  • Configure one IPv4 static route i.e. ipv4-route-a on the DUT for destination ipv4-network 203.0.113.0/24 with the next hop set to the IPv4 address of ATE port-1
  • Configure another IPv4 static route i.e. ipv4-route-b on the DUT for destination ipv4-network 203.0.113.0/24 with the next hop set to the IPv4 address of ATE port-2
• Validate both the routes i.e. ipv4-route-[a|b] are configured and reported correctly
  • /network-instances/network-instance/protocols/protocol/static-routes/static/prefix
