BMP-2.7: BMP Pre Policy Test

Summary

Validate BGP Monitoring Protocol (BMP) for pre policy routes

Testbed type

Procedure

Configuration

  1. Create the topology below:
graph LR; 
A[ATE:Port1] --EBGP--> B[Port1:DUT:Port2];
B --BMP--> C[Port2:ATE];
Loading
  1. Establish Topology: Set up the physical connections as described in the topology diagram.
  • Connect ATE Port 1 to DUT Port 1.
  • Connect ATE Port 2 to DUT Port 2 (simulating the BMP monitoring station).
  • Connected interface should have dual address family supported i.e. it should have both IPv4 & IPv6 addresses

  1. Interface Configuration: Configure IPv4 and IPV6 addresses on all involved interfaces on both the ATE and the DUT.

  2. Establish BMP Session: Configure and establish BMP session between the DUT and ATE port2 i.e. BMP station.

  3. Establish eBGP session between ATE port-1 (AS 64530) and DUT port-1 (AS 64520)

  4. Configure BMP on the DUT with the following parameters:

    • statistics-timeout: 60 seconds

    • connection-mode: active

    • local-address: 172.16.1.1

    • station-address: 10.23.15.58

    • station-port: 7039

    • route-monitoring: pre-policy

    • exclude-noneligible: true

  5. Advertise 15mil * IPV4 routes and 5mil * IPV6 routes

  6. Should be RFC7854 compliant

Test Setup Verification

Verify BMP session establishment

  1. Configure BMP station on ATE port-2 with address 10.23.15.58 and port 7039
  2. Verify that the DUT initiates a BMP session to the station (connection-mode: active)
  3. Using OTG, verify the ATE has an active BMP session with the DUT.
  4. Validate that the DUT connects to the correct station-address (10.23.15.58) and port (7039) with pre-policy route monitoring.
  5. Using gNMI, verify the DUT returns syntactically valid paths and values for all the below paths are present
 /network-instances/network-instance/protocols/protocol/bgp/global/bmp/state/local-address:
 /network-instances/network-instance/protocols/protocol/bgp/global/bmp/stations/station/state/address:
 /network-instances/network-instance/protocols/protocol/bgp/global/bmp/stations/station/state/port:

 /network-instances/network-instance/protocols/protocol/bgp/global/bmp/stations/station/state/uptime:
 /network-instances/network-instance/protocols/protocol/bgp/global/bmp/stations/station/state/policy-type:
  1. Check the session-state telemetry path to confirm the session is established

Tests

BMP-1.2.1: Verify route monitoring with pre-policy and exclude-noneligible

  1. Configure an import policy on the DUT to reject prefixes matching 172.16.0.0/16 and 2001:DB8::/32 from ATE port-1
  2. Have ATE port-1 advertise prefixes 15mil IPv4(the routes should include prefixes in range 172.16.0.0/16 ) and 5mil IPv6 (the routes should include prefixes in range 2001:DB8::/32) to the DUT
  3. Verify that the DUT and ATE (BMP station) receives route monitoring messages for IPV4 & IPV6 for 15mil IPV4 and 5mil IPV6
  4. Verify that the DUT and ATE (BMP station) receive route monitoring messages for routes excluded by the import policy i.e. all 15mil IPv4 and 5mil IPV6 should be received by BMP station.
