Procedure

Applying configuration

For each section of configuration below, prepare a gnmi.SetBatch with all the configuration items appended to one SetBatch. Then apply the configuration to the DUT in one gnmi.Set using the replace option.

WARNING: Replace operations should be performed at an appropriate level in the config tree to ensure that preexisting configuration objects necessary for DUT management access and base operation are not removed.

Initial Setup:

• Connect DUT port-1, 2 to ATE port-1, 2
• Configure IPv4/IPv6 addresses on the ports
• Create an IPv4 networks i.e. ipv4-network-1 = 192.168.10.0/24 attached to ATE port-1
• Create an IPv6 networks i.e. ipv6-network-1 = 2024:db8:128:128::/64 attached to ATE port-1
• Create an IPv4 networks i.e. ipv4-network-2 = 192.168.20.0/24 attached to ATE port-2
• Create an IPv6 networks i.e. ipv6-network-2 = 2024:db8:64:64::/64 attached to ATE port-2
• Configure IPv4 and IPv6 iBGP between DUT Port-1 and ATE Port-1
  • /network-instances/network-instance/protocols/protocol/bgp/global/config
  • /network-instances/network-instance/protocols/protocol/bgp/global/afi-safis/afi-safi/config/
  • Advertise ipv4-network-1 = 192.168.10.0/24 and ipv6-network-1 = 2024:db8:128:128::/64 from ATE to DUT over the IPv4 and IPv6 eBGP session on port-1 with:
    • MED = 50
    • Local Preference = 50
• Configure IPv4 and IPv6 eBGP between DUT Port-2 and ATE Port-2
  • /network-instances/network-instance/protocols/protocol/bgp/global/config
  • /network-instances/network-instance/protocols/protocol/bgp/global/afi-safis/afi-safi/config/
  • Advertise ipv4-network-2 = 192.168.20.0/24 and ipv6-network-2 = 2024:db8:64:64::/64 from ATE to DUT over the IPv4 and IPv6 eBGP session on port-2. The ATE should advertise both prefixes with:
    • MED = 50
    • Local Preference = 50

Verification

• Verify that policies are successfully applied to the DUT BGP neighbor on ATE Port-2 and default policies are set to REJECT_ROUTE

Validate test results

• Validate that the ATE receives the prefix ipv4-network-1 from DUT neighbor on ATE Port-2 and it has 11 ASN on as-path. First 10 equal to 23456 and last equal to DUT's ASN.
• Validate that the ATE receives the prefix ipv6-network-1 from DUT neighbor on ATE Port-2 and it has 11 ASN on as-path. First 10 equal to 23456 and last equal to DUT's ASN.
• Validate that the ATE receives the prefix ipv4-network-2 from DUT neighbor on ATE Port-1 and it has 11 ASN on as-path. First equal to ATE port-2 ASN and other 10 equal to 23456 ASN.
• Validate that the ATE receives the prefix ipv6-network-2 from DUT neighbor on ATE Port-1 and it has 11 ASN on as-path. First equal to ATE port-2 ASN and other 10 equal to 23456 ASN.
