Jeff,
Keepalive defined on the local peer will be used if there is none specified
on the remote-peer statement and if none defined on local peer as well then
the default is 30 seconds,
As keepalives are disabled so in order for the DSLW peers to detect the
failure tcp-timeout value is used with keepalive 0 as <timeout>, note as it
is a tcp timout so will only work
when a cct is active and being used and if a tcp timeout expires and no
response from destination peer then peer connection goes disconnected.
So without any Netbios test machines you will never be able to get them
disconnected.
Dynamic keword is used to dynamically set up and tear down peers
conenctions.
1) When an explorer needs to go through peers get connected to each other
2) It will stay up unless the options no-llc or inactivity is used (these
only avaliable after using the dynamic keyword and dynamic keyword only
avaliable if keepalive 0 used)
no-llc- only disconnect if idle time exceeds and no llc connection (i.e no
ckt active b/w the peers)
inactivity- disconnect if no data b/w peers (even if ckts are active but
sitting idle)
HTH
