Fan,
Yes you are right. That is being extremely stringent:
by only allowing ICMP.
Here is the REAL (one of several) solutions.
R1(receiving the call)
interface BRI0
ip address 133.10.33.1 255.255.255.0
encapsulation ppp
dialer idle-timeout 60
dialer map ip 133.10.33.2 name d11-2500-5_R5 broadcast
99065592
isdn switch-type basic-net3
no peer neighbor-route * note
no cdp enable * note
ppp authentication chap
end
R2 (initiating the call)
interface BRI0
ip address 133.10.33.2 255.255.255.0
encapsulation ppp
ip ospf demand-circuit * note
dialer idle-timeout 60
dialer map ip 133.10.33.1 name d11-2500-1_R1 broadcast
99065143
dialer-group 1 * note
isdn switch-type basic-net3
no peer neighbor-route * note
no cdp enable * note
ppp authentication chap
end
access-list 111 permit ip any any
dialer-list 1 protocol ip list 111
NB:
The dialer-list is only required on the router
initiating the call. Obviously this will be the router
you configure "ip ospf demand-circuit". Furthermore to
test to make sure this works, on R2:
debug dialer pack
debug dialer event
debug ip ospf monitor
Go to the neighbor OSPF router of R2 - enter:
#clear ip ospf proc
and you will see the link on R2 come UP. It is
fantastic as only OSPF recovergence/activity triggers
the link.
If you have questions email, I have tested this with
12.1(5)T9
Rgds,
Sage
