Hi all,
in a lab setup, I have two 2611XM connected via ISDN.
Router A (customer) tries to connect to Router B (ISP).
This works fine, as long as I choose encapsulation ppp.
This does not work when I choose encapsulation frame-relay.
Router A (customer) is FR DTE, Router B (ISP) is FR DCE. Using a DLCI of 123, I get a working Frame-Relay connection:
- PVCs are there and active
- frame relay mapping is ok (static, active)
- ping echo requests sent from Router A are seen at router B.
However, when router B tries to answer these request, I get an "encapsulation failed" error on Router B.
As soon as I switch back to ppp, everything works fine, so I guess it's no ISDN-problem.
Thanks in advance,
Oliver
Here are the two configurations :
Router A:
!
interface BRI0/0
ip address 12.0.0.1 255.0.0.0
encapsulation frame-relay
dialer idle-timeout 300
dialer string 20
dialer-group 1
isdn switch-type basic-net3
isdn point-to-point-setup
frame-relay map ip 12.0.0.2 123
frame-relay interface-dlci 123
end
Router B:
!
interface BRI0/0
ip address 12.0.0.2 255.0.0.0
encapsulation frame-relay
dialer idle-timeout 300
isdn switch-type basic-net3
isdn point-to-point-setup
frame-relay map ip 12.0.0.1 123
frame-relay interface-dlci 123
frame-relay intf-type dce
end
