Difference between the two versions:
The NE40E of versions earlier than V600R003 does not support ORF and cannot identify the ORF type in an Open message. Therefore, the NE40E ignores the Open message and does not parse ORF, and the BGP peer relationship can be established. The NE40E of V600R003 supports ORF and completely analyzes the ORF type in an Open message. The ORF type in the Open message from the Alcatel-Lucent device is different from that defined in RFC 5292, leading to a failure in establishing a BGP peer relationship.
Interoperation between Huawei NE40E and Cisco or Juniper devices:
The NE40E can establish a BGP peer relationship with a Cisco or Juniper device. These devices support the same ORF type.
