Hmmm... how have you managed to have a next hop address of 10.7.26.2 on
your vlan74 interface, when the local network appears to be 10.1.26.0/23
? What's the route to 10.7.26.2 -- presumably this is also accessible
on vlan74 ?
It certainly seems odd that your routes have disappeared, but I'm
wondering if they were culled from the routing table because the system
thought they weren't logically connected to the local system? Given
that they have seen traffic, perhaps this was connected to a different
change that the deletion of 10.1.26.1 that you highlighted?
Cheers,
Matthew
