Hello
Could use litle help with debugging a problem.
Long story short, i made working config using lab equipment at hand (srx 210 + mikrotik), everyting worked as expeted. But when i transferred same confix to srx 5400 then ospf started to give trouble. Ospf hello packets dont reach mikrotik.
Basic idea is:
ipsec + gre tunnel, pings are OK, but i think mtu is the problem.
Tests:
srx210 to mikrotik "ping x.x.x.x size 9148 do-not fragment" OK
mikrotik to srx210 "ping x.x.x.x size 1414 do-not fragment" OK
Moving to srx 5400
srx210 to mikrotik "ping x.x.x.x size 1386 do-not fragment" OK (only 1386) - is that causing ospf hellos not to reach mikrotik
mikrotik to srx210 "ping x.x.x.x size 1414 do-not fragment" OK
