EVPN routes (type-2/type-5) are imported from default bgp instance (where they are learnt) to non-default vrf instance. When a bgp instance (default) is deleted, unimport evpn routes from vrfs. In absence of unimport, the imported routes in vrf has parent path info points to default instance's path info which is no longer valid (if instance is deleted). When accessing parent path info leads to a crash in non-default vrf instance. The bgp instance is not cleaned up when 'no router bgp ASN' is performed, the instance's reference count remains for evpn imported routes. Ticket:CM-24484 Reviewed By: Testing Done: Validated via learning EVPN type-2/type-5 routes in symmetric routing scenario. The routes are imported to VRFs based on corresponding L3VNI. When the default instance is removed, the evpn routes are cleaned up from the VRF instance.
