A rotary group's purpose is to bind a single virtual dialer interface to
multiple physical bri interfaces. The dialer rotary-group # that is part of
the physical interface bri # configuration must match the dialer interface
number.Dialer maps work best with this type of configuration.
Interface bri 0
no ip address
dialer rotary-group 1
isdn switch-type basic-ni1
isdn spid1 xxxxxxxxxx
isdn spid2 xxxxxxxxxx
!
Interface bri 1
no ip address
dialer rotary-group 1
isdn switch-type basic-ni1
isdn spid1 xxxxxxxxxx
isdn spid2 xxxxxxxxxx
!
Interface dialer 1
ip address x.x.x.x x.x.x.x
dialer-group 2
dialer map ip x.x.x.x xxxxxx
!
dialer-list 2 protocol ip permit
(your static route must be to a next hop ip and not the interface)
A dialer pool or dialer profile's purpose is to bind multiple virtual dialer
interfaces to a single physical bri interface. The interface dialer is bound
to the interface bri by dialer pool #. Dialer strings work best with this
type of configuration:
Interface bri 0
no ip address
dialer pool-member 3
dialer pool-member 4
isdn switch-type basic-ni1
isdn spid1 xxxxxxxxxx
isdn spid2 xxxxxxxxxx
!
Interface dialer 1
ip address x.x.x.x x.x.x.x
dialer pool 3
dialer-group 2
dialer string xxxxxx
!
Interface dialer 2
ip address x.x.x.x x.x.x.x
dialer pool 4
dialer-group 2
dialer string xxxxxx
!
dialer-list 2 protocol ip permit
ip route x.x.x.x x.x.x.x interface dialer1
ip route x.x.x.x x.x.x.x interface dialer 2
Lastly, there is the humble legacy configuration which lumps everything into
the physical interface bri. This configuration requires the least amount of
typing. Dialer maps work best with this type of configuration:
Interface bri 0
ip address x.x.x.x x.x.x.x
isdn switch-type basic-ni1
isdn spid1 xxxxxxxxxx
isdn spid2 xxxxxxxxxx
dialer map ip x.x.x.x xxxxxxx
dialer-group 2
!
dialer-list 2 protocol ip permit
!
ip route x.x.x.x x.x.x.x x.x.x.x

Can someone explain to me the difference in binding the dialer intf to the
physical BRI itf using dialer rotary-group vs. dialer pool-member? When
would I use one over the other?
Thanks in advance.
