According to demands of MAN at some site, the inbound and outbound traffic of S8016 attached users are AR46GSR12012－－GSR12016. But the traffic of user network segment under AR46 is load balancing of two rotues: AR46-S8016－GSR12012－GSR12016 or AR46－S8016－NE80－－GSR12416. The topology can be referred to the attachment.
1. Check configuration of S8016 and no network segment is enabled routing policy.
2. Check configuration of AR46. The imported static route in OSPF of AR46 is TYPE 2. Change type2 as type 1 and the problem is solved.
1. The cost of S8016－GSR12012－－GSR12016 and S8016－－ERX1400－－NE80－－GSR12416 is equal.
2. The type of imported static route in OSPF of AR46 is TYPE 2.
If the egress router has two or more ASBR, it is suggested that the type of imported route is type1. If the egress router has one ASBR, the imported route can be type 2 and type 1.
