Thanks for the reply,
I am supposing a task where the default route should be there only if the
ser0/0 is down,
If serial 0/0 is up, ospf will be running, and R5 will know all routes.
There should be no routing protocol on ISDN.
If serial 0/0 is up, R5 should discard packets for which there is no entry
on RIB from OSPF.
Do you think there is a way to do so?
Cordially

RE: ISDN - default route
Why don't you keep a higher admin distance (ip route 0.0.0.0 0.0.0.0
<next-hop> <higher admin-dist than existing routing protocol>

Subject: ISDN - default route
How would you configure a default route pointing to ISDN so it is on the
RIB only when the main interface is down?
I tried pointing to physical BRI (ip route ...bri0/0), but I get an
encapsulation failed for the addresses not mapped under bri (dialer map
ip...)
I tried pointing to Dialer (ip route...dialer 200), but the default route
is always on the RIB in this case.
I tried pointing to the remote IP of the ISDN (ip route 172.16.45.5), but
the default route is always on the RIB in this case either.
Tested using legacy with this config:
interface BRI0/0
description testar dialer load-trheshold only on R5
ip address 172.16.45.6 255.255.255.252
encapsulation ppp
dialer map ip 172.16.45.5 name Rack2R4 broadcast 4441111111
dialer-group 1
isdn switch-type basic-ni
isdn spid1 555111111100
isdn spid2 555222222200
no cdp enable
ppp authentication chap
ppp multilink
Testing using dialer profile with this config:
interface BRI0/0
no ip address
encapsulation ppp
dialer pool-member 200
isdn switch-type basic-ni
isdn spid1 555111111100
isdn spid2 555222222200
ppp authentication chap
ppp multilink
interface Dialer200
description testar dialer load-trheshold only on R5
ip address 172.16.45.6 255.255.255.252
encapsulation ppp
dialer pool 200
dialer remote-name Rack2R4
dialer string 4441111111
dialer-group 1
no cdp enable
ppp authentication chap
ppp multilink
