Remember that access-list 901 is defining what is allowed to trigger
a call, it is not defining what packets are allowed to travel across the
ISDN link. So 901 is denying RIP, SAP, serialization from bringing up the
line but when the line is up RIP and SAP broadcast to the other router and
vice-versa. Snapshot controls when the line is brought up depending on your
snapshot timers and then RIPs and SAPs keep the route table and SAP table
synchronised on both routers during the active Snapshot period.
901 is just there to stop the RIP and SAP broadcasts from triggering
a call.
