I have 2 routers, each router has 2 x E1 cards and they are connected back-to-back.
If I configure each pair of E1 individual, with FR everything works fine. I bundle the E1 interfaces into a FR multilink, the MFR interface is UP, multilink is reported UP, but no traffic is passing through it. Everything seems to be fine, but (for example) I cannot ping between this 2 routers.
The strange fact is that when I issue "sh frame-relay pvc" there are no INPUT packets. Debugging is showing me only sent packets.
I changed the frame-relay encapsulation (Cisco / IETF), tried different scenarios / parameters, change MTU size...nothing helped so far.
Do you have any idea, advice for me?
Thanks a lot!
it was the no arp frame-relay.
you used LMI keepalive with one side as DCE.
Nice to hear you solved the issue
about the solved symbol only you could set it on someebody else's answer because you have started the thread.
