861.0. "AW90EI/ISDN ip/bridging config details?" by SNOFS1::63496::CHIUANDREW () Thu Apr 17 1997 00:40

    Hi,
    
    Just want to confirm the steps to config ISDN on AW90EI for IP routing
    and bridging:
    
    talk 6
    
    1) config>add isdn-address local_router 11111 01 -> add local ISDN info 
              add isdn-address remote_router 22222 02 -> add remote ISDN
    
    2) config>add dev dial   -> this is to create psudeo device PPP (net 3)
                                to use ISDN net 2
    
    3) config>net 2          -> goto isdn interface to set switch variant
                                and local isdn info
       ISDN>set local local_router
       ISDN>set switch austel
       
    4) config>net 3          -> goto to net 3 (psudeo device PPP)
       Circuit Config>set net 2  -> map to ISDN net 2 
       Circuit Config>set dest remote_router  -> call will goto the remote
       Circuit Config>set inbound remote_router  -> only accept incoming 
                                                    call from remote (i.e.
                                                    calling isdn number
    						    must 2222202
    5) config>prot ip
       IP config>add address 3 192.168.1.1 255.255.255.0
       IP config>add route 0.0.0.0 0.0.0.0 192.168.1.2 5  -> this is to add
    	                                                    static route to 
                                                            point to ISDN
    	                                                    interface at
                                                            remote router
    
    Turn off routing protocols on net 3.
        
    6) config>prot asrt
    ASRT config>add port 3 2  -> create a bridge port #2  on net 3 (i.e.
                                 bridging over ISDN net 2)
    
    
    Any comments/ideas?
    
    
    thanks in advance for help!

    You probably need to set DN0 UNLESS you are running fixkit2 (V2.0.3).
    Before that, the address you assigned to 'local_router' got copied into
    DN0, which isn't necessarily correct.  If incoming calls fail, this is
    probably why.  Look for event ISDN.041 to see what the switch thinks
    your DN0 should be.
    
    
>      Circuit Config>set inbound remote_router  -> only accept incoming 
       
    Only really required if it was different than the setting for 'dest' --
    which it isn't in your case.
    
    Your IP configuration looks OK, I'm not sure about bridging...beware
    that your link will probably never go idle with bridging turned on!

861.2What DN0 had to do with 'local_router'?SNOFS1::63496::CHIUANDREWThu Apr 17 1997 20:3325
    re .1,
    
    Thanks for your quick reply!
    
    Your answer to
    >> You probably need to set DN0 UNLESS you are running fixkit2
    (V2.0.3).
    
    Could you please explain what do you mean by DN0 ...??
    I am using switch variant 'austel' and accorinding to manual DN0
    only apply to VN3 and NET3, is it correct?
    
    I am running V2.0.2 Aw90EI, and once I SET LOCAL LOCAL_ROUTER
    and SET SWITCH AUSTEL, the local network address
    name/address/sub-address were copied to DN0.
    
    Or am I missing something?
    
    Yes, customer would like to use bridging and they will have a SPC ISDN
    circuit (using one B-channel permanent). Surely, we might turn routing
    protocols later on to enhance routing convergent.
    
    
    thanks again for help!

    That isn't correct.  Which manual is this?

    That is a bug, in my opinion, which has been fixed in V2.0.3.  It is not
    usually the case that your local ISDN address is the same as the DN0
    supplied by the PTT.  Often they only send the last digit of the ISDN
    number, etc...Which is why it was changed in V2.0.3.
    
    Best thing to do is get this update, CLEAR ISDN, and reconfigure the
    ISDN network (net 2).  You won't need to set DN0 unless you plan to
    share the S-BUS amoungst multiple devices (like an ISDN phone, etc...)

    Is this the Australian version of semi-permanent ISDN circuits?  We
    don't really support semi-permanent operation, although from what I
    know of the Australian methods it ought to work -- though the line
    won't stay up permanently (we will redial the call after every router
    restart/powerup).
