TE-8.2: Supervisor Failure

Summary

Ensure that gRIBI entries are persisted over supervisor failure.

Testbed type

• https://github.com/openconfig/featureprofiles/blob/main/topologies/atedut_2.testbed

Procedure

Test environment setup:

• Connect DUT port-1 to ATE port-1, DUT port-2 to ATE port-2.
• Assign IPv4 addresses to all ports.

TE-8.2.1 - FIB Programming and Switchover Validation

• Connect gRIBI client to DUT specifying persistence mode PRESERVE, SINGLE_PRIMARY client redundancy in the SessionParameters request, and make it become leader. Ensure that no error is reported from the gRIBI server.

• Add 50 IPv4Entrys (starting at 203.0.113.1/32) and 50 IPv6Entrys (starting at 2001:db8:203:0:113::1/128) pointing to ATE port-2 via gRIBI-A. Ensure that the entries are active through AFT telemetry and correct ACK is received.

• Send traffic from ATE port-1 to the 100 prefixes (50 IPv4 and 50 IPv6), and ensure traffic flows 100% and reaches ATE port-2.

• Validate: Supervisor switchover is triggered using gNOI SwitchControlProcessor. Ensure gRIBI entries persist over switchover and traffic contniues to be forwarded.

• Following reconnection of a gRIBI client to the new master supervisor, ensure the 100 prefixes pointing to ATE port-2 are present and traffic flows 100% from ATE port-1 to ATE port-2.

TE-8.2.2 - Post Switchover FIB Programming Validation

• Add another 50 IPv4Entrys (starting at 203.0.114.1/32) and 50 IPv6Entrys (starting at 2001:db8:203:0:114::1/128) pointing to ATE port-2. Ensure that these new entries are active through AFT telemetry and correct ACKs are received.

• Send traffic to all 200 prefixes (100 initial + 100 post-switchover) and ensure traffic flows 100% from ATE port-1 to ATE port-2.
