[GTER] perda de neighbor em OSPF

[Marcelo Szeer]

Boa tarde... 

Gostaria de perguntar aos mais experientes se já viram esse tipo de problema no Router OS 5.8, onde de forma aleatória e sem padrão, perde-se o Neighbor no OSPF.


14:59:13 route,ospf,info OSPFv2 neighbor 10.81.255.254: state change from Full to 2-Way
15:00:23 route,ospf,info OSPFv2 neighbor 10.81.255.254: state change from Full to Init
OSPFv2 neighbor 10.81.255.254: state change from Full to Init
15:01:58 route,ospf,info Database Description packet has different master status flag
15:01:58 route,ospf,info new master flag=false
15:01:58 route,ospf,info OSPFv2 neighbor 10.81.255.254: state change from Full to 2-Way
15:03:54 route,ospf,info OSPFv2 neighbor 10.81.255.254: state change from Full to Init
15:04:24 route,ospf,info OSPFv2 neighbor 10.81.255.254: state change from Full to Init
15:07:44 route,ospf,info OSPFv2 neighbor 10.81.255.254: state change from Full to Init
15:10:39 route,ospf,info OSPFv2 neighbor 10.81.255.254: state change from Full to Init
15:13:49 route,ospf,info OSPFv2 neighbor 10.81.255.254: state change from Full to Init


entre o roteador que gerou estes logs e o 10.81.255.254 existe um enlace wireless com RAD Airmux-400...

o enlace wireless parece estável mas o OSPF fica perdendo adjacência com o vizinho...

# ROUTER-ID ADDRESS STATE STATE-CHANGES
0 10.81.255.254 10.81.255.189 Full 212

e neste processo leva todas as rotas junto com ele... o segmento desta rede toda fica instável...

ambos roteadores RouterOS v5.8 rodando em RouterBoard 450G...

alguém já viu isso ? 

grato,

Marcelo Szeer
