Nikolay,
you want to try this:
R3:
interface Serial0/0/0
encapsulation frame-relay cisco
R3:
interface Serial0/0/0
encapsulation frame-relay ietf
In your current configuration both sides use default encapsulation (cisco).
hth,
srdja

Subject: Frame-realy encapsulation ietf/cisco
Dear friends,
I have a question about the encapsulation of the frame relay between two
sides. As long as I know the encapsulation of the end DTE devices should be
the same. It has nothing to do with the frame-relay switch.
I made some test and I am totally confused. No matter what encapsulation I
put on on each side I always have connectivity. No matter that on one side
it is cisco on the other ietf.
Router 3
interface Serial0/0/0
ip address 154.1.0.3 255.255.255.0
encapsulation frame-relay
ip ospf network point-to-multipoint non-broadcast frame-relay map ip
154.1.0.4 304 IETF frame-relay map ip 154.1.0.5 305 no frame-relay
inverse-arp
Router 4
interface Serial0/0/0
ip address 154.1.0.4 255.255.255.0
encapsulation frame-relay
ip ospf network point-to-multipoint non-broadcast frame-relay map ip
154.1.0.3 403 frame-relay map ip 154.1.0.5 403 no frame-relay inverse-arp
R4#ping 154.1.0.3 repeat 10
Type escape sequence to abort.
Sending 10, 100-byte ICMP Echos to 154.1.0.3, timeout is 2 seconds:
!!!!!!!!!!
Success rate is 100 percent (10/10), round-trip min/avg/max = 8/10/12 ms
Please help me with this confusion. Should I make them the same on both
sides or it doesn't matter ?
Thanks
Nick
