Validate BGP in multipath scenario
- Connect DUT port 1, 2, 3 and 4 to ATE port 1, 2, 3 and 4 respectively
- Configure IPv4/IPv6 addresses on the interfaces
- Establish eBGP sessions between:
- ATE port-1 and DUT port-1
- ATE port-2 and DUT port-2
- ATE port-3 and DUT port-3
- ATE port-4 and DUT port-4
- Enable an Accept-route all import-policy/export-policy for eBGP session under the neighbor AFI/SAFI
- Create an IPv4 internal target network attached to ATE port 2, 3 and 4
-
RT-1.51.1: Verify best path
- Configure ATE devices(ports) on same AS
- Advertise equal cost paths from 3 interfaces of ATE of same AS
- Check entries in FIB for advertised prefix, it should only have 1 entry
- /network-instances/network-instance/afts/next-hop-groups/next-hop-group/next-hops
- Initiate traffic from ATE port-1 to the DUT and destined to internal target network
- Check entire traffic should only be forwarded by one of DUT port2, port3 or port4
-
RT-1.51.2: Enforcing multipath hence ECMP scope to only one peer AS
- Configure ATE devices(ports) on same AS
- Enable multipath and set maximum-paths limit to 2
- /network-instances/network-instance/protocols/protocol/bgp/peer-groups/peer-group/afi-safis/afi-safi/use-multiple-paths/config/enabled

- Advertise equal cost paths from 3 interfaces of ATE of same AS
- Check entries in FIB for advertised prefix, it should only have 2
entries
- /network-instances/network-instance/afts/next-hop-groups/next-hop-group/next-hops
- Initiate traffic from ATE port-1 to the DUT and destined to internal target network
- Check entire traffic should only be equally forwarded by any two among DUT port2, port3 or port4
-
RT-1.51.3: Verify use of allow-multiple-as for ECMP routing across different peer AS
- Configure ATE devices(ports) on different AS
- Enable multipath, set maximum-paths limit to 2 and enable allow multiple
AS
