I have two routers connected by a ubi wireless link. Until recently they worked fine with OSPF beween them with a bit of flapping recently , but now they won't
work at all.
R1 ----- AP ------ STA ----- R2
Both routers are connected on ether 1
Both R1 and R2 are running ospf and work fine with other routers on different interfaces on the same routers like ether2 etc.
Network statements are correct for the ether1 interface of each router, same subnet on each.
Both packet sniffing and OSPF debug logs show conclusively that
R1 sends a HELLO packet from its IP, and R2 recieves that HELLO.
R2 sends a HELLO packet from its IP, but R1 'does not receive it' at all,' jjust .gone.
Thus the two routers hang in a INIT state, never getting any further.
There are no logs on R1 concerning the missing HELLO from R2.
R2 packet sniff and ospf logs says packet was sent.
R1 shows nothing.
