Frame relay sub interface ietf

Apr 28, 2012 1:24 PM

Hey guys,

 

I have a hq router,with 3 branch routers point to point. with sub interfaces on hq. 2 sub interfaces use cisco 2 use ietf.

 

hq. s0/0/0 no ip add, s0/0/0.41,s0/0/0.42,s0/0/0.43

 

branches have s0/0/0 as the interface

 

I'm having trouble putting ietf on a point-to-point sub interface. since point to point sub interfaces use the:

 

frame relay int dlci #

 

and not the

 

frame relay map ip # dlci# (ietf,ciso)

 

I know your going to say go change it at the S0/0/0

 

with

 

encap frame-relay ietf

 

Well I can't do that because my other 2 sub interfaces under s0/0/0 are cisco..

 

 

IDK.

 

Thanks,

 

Cameron

    I guess this is not real gear or  if it is, you have IOS version that does not support command u need;

     

    R5(config-subif)#frame-relay interface-dlci 106 ?

      cisco     Use CISCO Encapsulation

    ietf      Use RFC1490/RFC2427 Encapsulation

      ppp       Use RFC1973 Encapsulation to support PPP over FR

      protocol  Optional protocol information for remote end

      <cr>

     

    R5(config-subif)#frame-relay map ip 1.1.1.1 106 ?

      broadcast            Broadcasts should be forwarded to this address

      cisco                Use CISCO Encapsulation

      compress             Enable TCP/IP and RTP/IP header compression

      ietf                 Use RFC1490/RFC2427 Encapsulation

      nocompress           Do not compress TCP/IP headers

      payload-compression  Use payload compression

      rtp                  RTP header compression parameters

      tcp                  TCP header compression parameters

      <cr>

     

    Result is

    interface Serial1/0

    no ip address

    encapsulation frame-relay

    shutdown

    serial restart-delay 0

    !

    interface Serial1/0.105 multipoint

    frame-relay map ip 1.1.1.1 105 IETF

    !

    interface Serial1/0.106 point-to-point

    frame-relay interface-dlci 106 IETF

    !

    Well, Frame relay labbing is the best in GNS3;

    there are other missing commands in PT regarding FR.

    Time to move to GNS3
