Hi
I need some help to understand a problem with my OSPF…
I have a router at the end of a wireless point-to-point, to serve some wireless clients. This RB have 2 wireless cards, 1 to clients (10.0.x.1) and another to the wireless point-to-point (172.16.x.2).
RB1|172.16.x.1 <–wireless ptp–> 172.16.x.2|RB2|10.0.x.1 (clients)
OSPF is implemented in all my network, and only in this RB (RB2) I have the following lines in the log:
13:28:04 route,ospf,info Database Description packet has init bit set in middle of an exchange
13:28:04 route,ospf,info OSPF neighbor 172.16.x.1: state change from Full to 2-Way
RB1 reports in log:
13:28:05 route,ospf,info OSPF neighbor 10.0.x.1: state change from Full to Down
The wireless link is ok - high quality, high uptime in registration, and when I test pings from RB1 (172.16.x.1) at the same time to 172.16.x.2 and 10.0.x.1 (same RB2), only the 10.0.x.1 sometimes looses a sequence of packets. The 172.16.x.2 responds perfectly, so, the problem does not appear to be the link.
When this occurs, the dynamic ospf route to 10.0.x.0 disappear in the RB1, so this is the obvious reason that 10.0.x.1 does not respond some sequences.
This problem appeared yesterday, and since this, occurs frequently. In both RB´s the Mikrotik version is 3.27.
Any help will be very appreciated. I will paste below some other useful informations.
Thanks in advance.
