Enable "encapsulation frame-relay" on the interface first. If you are trying
the command on a standard serial with HDLC or PPP encapsulation the command
will not show up because the default is point-to-point for those interface
encapsulations.

Here is an example configuration with a Frame-Relay point-to-point
subinterface connected to a Frame-Relay multipoint subinterface using the
"isis network point-to-point" command on the multipoint interface side:

** R3 Config **
interface Loopback0
 ip address 201.163.6.3 255.255.255.255
!
interface Serial1/1
 no ip address
 encapsulation frame-relay
!
interface Serial1/1.1 point-to-point
 ip address 10.35.35.35 255.255.255.0
 ip router isis
 frame-relay interface-dlci 315
!
router isis
 net 49.0001.0003.0003.0003.00
 passive-interface Loopback0
end

** R5 Config **
interface Serial0/0
 no ip address
 encapsulation frame-relay
!
interface Serial0/0.1 multipoint
 ip address 10.35.35.53 255.255.255.0
 ip router isis
 isis network point-to-point
 frame-relay map clns 513 broadcast
 frame-relay map ip 10.35.35.35 513 broadcast
!
router isis
 net 49.0001.0005.0005.0005.00
end

R5 could have also have been a physical interface.

Could it be applied to Serial interface?
I have a same ios version. It doesn't seem to have an option for serial
interface.

There is a bit of conflict in that document. It says it was introduced
in
12.2.(8)T and it is supported on the 2600's, but the T code does not go
that
high for the 2600's.

Am I missing something?

Hello Thomas,

What version of code might that be in?
