Bug Description

QFX is advertising type 1 route with community target configured under switch-option (target:65000:1) which is different than RI route target. But contrail control does not have that in import target list. This particular vrf target is configured by DM and should be added in contrail control import list as well.

When route-target community is disabled seeing the route in bgp evpn table

[DM]: Push right QFX Leaf config for control-node to accept EVPN Type 1 routes (Multi Homing)

Following config will be pushed

set groups __contrail__ policy-options policy-statement _contrail_switch_export_policy_ term t1 then community add _contrail_switch_export_community_
set groups __contrail__ policy-options community _contrail_switch_export_community_ members target:65000:8000002
set groups __contrail__ switch-options vrf-export _contrail_switch_export_policy_

- Device Schema : CommunityType parameter 'members' is changed from scalar type to array.
More than one member is supported by JUNOS.

- Unit Tests will be added to mainline commit.
