Hi Victor,
You have two separate data links ( two frame relay circuits via FR SW).
It is very normal that you have different LMI/encapsulation types on
both links.
If you connect these routers back to back you would normally one
LMI/encapsulation type, but for this instance, we have FR SW in the
midle to convert and switch these circuits for us.
Regards,
Kemal

Subject: Encapsualtion Frame-relay
Hello people..
Please, I wish to understand the frame-relay encapsulation command
parameters.
I know that this could affect me in Layer 2 Framming, Compression, LFI
in QoS, etc..
In doing IETF mode we move from the default Cisco frame-relay
configuration, if the remote end is a non cisco device,
But, why in this configuration the PVC is up?
R1 ---- (FR SW) ---- R5
Rack1R5#show run interface serial 0/0
Building configuration...
Current configuration : 81 bytes
!
interface Serial0/0
no ip address
encapsulation frame-relay
cdp enable
end
Rack1R1#show run interface serial 0/0
Building configuration...
Current configuration : 74 bytes
!
interface Serial0/0
no ip address
encapsulation frame-relay IETF
end
As you can see
Rack1R1#fr pvc | in ACTIVE
DLCI = 105, DLCI USAGE = LOCAL, PVC STATUS = ACTIVE, INTERFACE =
Serial0/0
The DLCI to R5 is UP, and you can see that the encap in R5 is a Cisco
Encapsualation
Is there any link or any debug command that could help me understand a
little bit better this?
Thanks
Victor.
