Hmmm.... How about that schtuff... Good question then. (Sorry for not
being compeltely awake when I answered!) Well, in theory, it should have
acorrect representation. However, I'd feel better about seeing the show
interface response when the sub-if was actually in an up-up position, before
making any assumptions about it.

Thanks for replying but I dont think you caught the drift of my question. I
included some output so I could show you want the problem was. As you can
see
from the output even when you change the frame encap on the subinterface a
"show interface ser 1.1" command will still show the encap of the main
interface. Cosmetic bug or ? Please see below:
!
interface Serial1
no ip address
no ip directed-broadcast
encapsulation frame-relay
clockrate 64000
frame-relay intf-type dce
!
interface Serial1.1 point-to-point
ip address 1.1.1.2 255.255.255.0
no ip directed-broadcast
frame-relay interface-dlci 16 IETF<---shows as Cisco
!
interface BRI0
no ip address
router1#show int serial 1.1
Serial1.1 is down, line protocol is down

Of course. By default, sub-interfaces will inherit properties from the main

On a subif:
frame-relay interfac-dlci (#) ietf
will change the encapsulation for that particular PVC.
Hope that helps!

Subject: Frame Relay Question
Hello group
I have a question a customer of mine stumped me with. He asked if the frame
relay encapsulation could be diffirent on subinterfaces from the main
interface. I said yes they could as long as you specified it after the DLCI
statement. He asked me why when you do a "show interface ser 0.1" it
always
shows the same encapsulation that the main interface has even though you
specify a diffirent one on the subinterface. I tested it out and he is
right.
If you put encap IETF on the main interface and Cisco on the subinterface
(frame-relay interface-dlci 16 cisco) a show interface on the sub interface
will show it as "frame encap IETF" and vis versa. Irregardless of what
encap
you can still ping accross the PVC as long as both sides are Cisco (at least
in back to back serario) another thing I thought was not possible since
there
are slight diffirences in the frame.
Is this a cosmetic bug with the output of "show int" or was I wrong about
the
sub interfaces being able to be a diffirent encap then the main interface?
Thanks!
Scotty
