Hi,
I`m having trouble configuring dialer maps on BRI interfaces, or better
put having them work: Here is what I have for configs:
R4:
interface BRI0
ip address 165.10.192.4 255.255.255.0
encapsulation ppp
dialer map ip 165.10.192.6 name r6 broadcast
dialer-group 1
isdn switch-type basic-5ess
ppp authentication chap
ppp multilink
end
R6:
interface BRI0
ip address 165.10.192.6 255.255.255.0
encapsulation ppp
ip ospf demand-circuit
dialer map ip 165.10.192.4 name r4 broadcast 1111
dialer-group 1
isdn switch-type basic-5ess
ppp authentication chap
ppp multilink
end
the dialer list on both of them is:
dialer-list 1 protocol ip permit
when I try to ping the from R6 to R4s interface, the link is initiated
and all the PPP stuff looks fine, but in the dialer debug I see that R4
get a ping request and is sending a ICMP reply but to do this it tries
to dial back to R6 , but cant cause it has no number in dialer map. But
_why_ does it want to dial? The link is up already, I see a host/32
route pointing toward int BRI0 on R4, why would it want to dial back to
reply to a ping request?
And if I remove the dialer map from the R4, then I get replies fine.
Please help I`m loosing my mind for 3rd day in a row.
The routers are both 2503s running 12.2(27) c2500-js-l.122-27.bin. Here
is a debug of debug dialer, debug ppp negotiation, debug ppp
authentication and debug q931 from both of the routers:
