Error description
Basic issue is when we return device A we include all the local neighbour records separately and similarly for the remote neighbours. This was by design to simplify processing. e.g. if we have device A with four interfaces, each with 2 neighbours we'd return 13 records. A A.int1 A.int1.remA A.int1.remB A.int2 A.int2.remC A.int2.remD A.int3 A.int3.remE A.int3.remF A.int4 A.int4.remG A.int4.remH The problem is there are a lot of BGP which has a lot of BGP information in the local neighbour record and quite a few remote neighbours. This means that for each remote neighbor the BGP data is needlessly repeated. e.g.
