ros 7.5 ssh to ros 6.49.6 on same lan timeout

Thu Sep 29, 2022 9:49 pm

Hello Folks!

I upgraded ros 6.49.6 to ros 7.5 on one router the other day, now ssh between routers with ros 7.5 and ros 6.49.6 in same lan results in timeout.
Ping (icmp) works between them, arp tables are updated, but ssh and neither snmp works. Torching ether2 results you see traffic but that is all.

Trying from another lan both ssh and snmp works.

The upgraded router had OSPF enabled and running (also dude server) before upgrade, and so also after upgrade. It receives routing tables and advertises routing tables for all connected networks it has.
But I must admit I do not fully understand the new OSPF routing.
I torched all network interfaces trying to see if traffic slipped out some else way, but there is nothing.

I never seen something like this, not being able to do direct connections to another router on same lan, but icmp works and both ssh ans snmp works from other lans.
Anyone who have any ideas what this is ?
