Is-is log message

Hi ,

Please, somebody explain what happened if I receive the following message:

What means this log message ?

%CLNS-5-ADJCHANGE: ISIS: Adjacency to host (TenGigabit xx) Down, neighbor forgot us

%CLNS-5-ADJCHANGE: ISIS: Adjacency to host (TenGigabit xx) Down, neighbor forgot us

%CLNS-5-ADJCHANGE: ISIS: Adjacency to host (TenGigabit xx) Down, neighbor forgot us

What means "neighbor forgot us" ?

Is-is log message

Like in ospf, every time a router receives a hello from other router, includes its router id in its own hellos in a list of "known neighbors". This way, when the other neighbor receive this hello with its own router id included, know the other side see him. But it the router id is not in the received hello packet, we know the other side is not receiving our hellos and adjacency falls down, or cant be established.
