Dear Group need your help.
###############################################
R1 ------>>>> R2 <<<<------------- ISDN modem type TA device
##############################################
R1:- Cisco 1700 with One Leased Line (S0) as primary link
One BRI (BRI0) as backup to Leased Line
R2 :- Cisco 1700 with Leased Line (S0)
One BRI (BRI0)
ISDN TA(Modem) With one BRI line
Present scenario :-
Primary link connectivity is established between Router R1 and Router R2 via
Leased Line. If Leased line goes down then ISDN line from R1 (Configured as
Backup )comes up and dials to R2 and establishes the connectivity.
Requirement:-
In the existing setup also want to connect one remote location via some ISDN
TA type device which will dial to R2 and will use either of the B channel
from
one BRI line available and remain connected. Same time if Router R1's Leased
line goes down then BRI should come up and should connect to Router R2's one
of the available B channels. In this case Router R2 will act as central
office
router and R1 plus remote ISDN TA / Modem will dial to it.
Is it possible to have this kind of setup. Do I need to create dialer rotery
group or dialer pool on router R2. Can I get a sample config of this type if
its available on CISCO's web site.
Many thanks in advance
IT
