They both will work, the difference being the control mechanism added with
the acl. As far as keeping the dialer up, is the dialer side set as the STP
root? On global or interface, assign a higher priority, ex. bridge-group 1
priority 100.. Are the peers passive, promiscuous, on demand, or active? Set
a low keepalive number on local peer statements, and extend the timeout on
remote peer statements so that the session doesn't timeout while the circuit
initializes, and a keepalive value that is lower then the dialer idle time
should keep the circuit up..
dlsw local-peer peer-id 10.1.1.1 keepalive 10
dlsw remote-peer 0 tcp timeout 500
int dia0
dialer idle-time 90
