Example IP/IPX routing from OfficeConnect™
Remote 5xx series to a Cisco 2500.
PURPOSE OF PROCEDURE:
To Specify an example network set-up to test Point to Point Protocol
(PPP) and Multilink PPP (MP) interoperability between the 3Com
OfficeConnect™ Remote 5xx series bridge/routers and a Cisco
2500 to enable routing of IP and IPX over ISDN.
The procedure assumes OfficeConnect™ Remote experience.
This setup procedure explains simple configuration of IP and IPX routing from an OfficeConnect™ Remote 5xx series with version 05.03 code to a Cisco 2500 with version 11.0 code. Version 5.02 code for the OfficeConnect™ Remote 5xx series will only allow PPP. Other Cisco software versions may work, but they are not guaranteed.
INDEX Section 2 Enable PAP Authorization Section 3 Enable Multilink PPP
The first configuration is PPP only. PAP and CHAP is not used
in this set-up as CLI is assumed. If you do not have CLI then
section 2 shows how to enable PAP.
We will be routing IP from a remote network OfficeConnect™
Remote to a central site Cisco 2500 using static routes and a
numbered link.
The addressing is as follows: Cisco Unit Name = CENTRAL
OfficeConnect™ Remote Unit Name = REMOTE The central site Network = 193.10.10.x 255.255.255.0 with Cisco router address 193.10.10.1
The remote site Network = 89.x.x.x 255.0.0.0 with OfficeConnect™
Remote router address 89.1.1.1 The numbered link = 130.10.2.x 255.255.255.0 Cisco ISDN WAN address = 130.10.2.1
OfficeConnect™ Remote ISDN WAN address = 130.10.2.2
Line type ETSI Net3
N.B. A List of Switch types supported by Cisco is shown in
Appendix1.
Step 1: Set the Cisco to Factory Defaults
Type the following commands. ENABLE <cr> (Enter Password) WR ERASE <cr>
Wait 30 seconds and reboot Cisco
Step 2: Initial Configuration of Cisco.
The Cisco will now prompt you with initial configuration questions:
Prompt Answer ENTER INITIAL CONFIGURATION YES SEE CURRENT CONFIGURATION NO NAME CENTRAL SECRET PASSWORD ENABLE PASSWORD password VIRTUAL TERMINAL PASSWORD cisco SNMP NO VINES NO LAT NO APPLE NO DEC NO IP YES IGRP ROUTING NO RIP ROUTING YES CLNS NO BRIDGE NO IPX NO XNS NO APOLLO NO
BRI TYPE BASIC-NET3
CONFIGURE INTERFACE BRI0 IS THIS INTERFACE IN USE? YES CONFIGURE IP ADDRESS? YES CONFIGURATION IP ADDRESS 130.10.2.1
NUMBER OF BITS IN SUBNET 8
NB: Notice that the number of bit in subnet is 8 as this is
a class B address subnetted to class C
CONFIGURE INTERFACE ETHERNET PORT 0 IS THIS INTERFACE IN USE? YES CONFIGURE IP ADDRESS? YES CONFIGURATION IP ADDRESS 193.10.10.1
NUMBER OF BIT IN SUBNET 0 CONFIGURATION SERIAL INTERFACE
SERIAL 0 NO
SERIAL 1 NO
USE THIS CONFIGURATION YES
At this point the Cisco 2500 will compile these entries.
Step 3: Enter user names.
The usernames will be the names given to the OfficeConnect™
Remote and the Cisco EN <cr> PASSWORD <cr> CONFIG <cr> TERM <cr> username CENTRAL password PASSWORD <cr> username REMOTE password PASSWORD <cr> <Ctrl> Z
WR T <cr>
NB: The username passwords have been set to PASSWORD. When
configuration is written to flash, PASSWORD will be encrypted.
These passwords will be passive in the configuration until PAP
or CHAP is enabled. see section 2
Step 4: Enter ISDN interface parameters for PPP, SPID,dialer
map and dialer group. CONFIG <cr> TERM <cr> INT BRI0 <cr> ENCAPSULATION PPP <cr> DIALER MAP IP 130.10.2.2 NAME REMOTE ISDN number <cr> DIALER-GROUP 1 <cr> ISDN SPID 1 spid number ISDN number <cr>
ISDN SPID 2 spid number ISDN number <cr>
N.B. The SPID settings are only necessary in certain USA
applications <Ctrl> Z
WR T <cr> Step 5: Add static IP route, attach to Access List and dialer list
CONFIG <cr> TERM <cr> IP ROUTE 89.0.0.0 255.0.0.0 130.10.2.2 <cr> ACCESS-LIST 101 PERMIT IP ANY ANY <cr> DIALER-LIST 1 PROTOCOL IP LIST 101 <cr> <Ctrl> Z WR T <cr>
Step 6: Configuration of the OfficeConnect™ Remote
Set the OfficeConnect™ Remote to Factory Defaults with the following commands.
CO STD <cr>
Y <cr>
When unit has rebooted type SAVE <cr> Enter the QC NA screen (Items shown in parentheses are example entries as defined in SECTION 1)
OfficeConnect™ Remote NAME (REMOTE) OfficeConnect™ Remote LAN IP ADDRESS (89.1.1.1) OfficeConnect™ Remote LAN MASK (255.0.0.0)
SWITCH TYPE and SPIDS (For USA use ONLY)
Use the QC IN screen to set up Cisco NAME (CENTRAL) Cisco ISDN NUMBER, Cisco LAN NETWORK No. (193.10.10.1) Cisco LAN MASK (255.255.255.0) IP ADDRESS of Cisco ISDN WAN port (130.10.2.1) MASK of Cisco ISDN WAN port (255.255.255.0) IP ADDRESS of OfficeConnect™ Remote ISDN WAN port (130.10.2.2) MASK of OfficeConnect™ Remote ISDN WAN port (255.255.255.0)
Set Remote unit type to Cisco.
SECTION 2: ENABLE PAP AUTHORIZATION
Step 1: Enable PAP on the Cisco Router.
Type the following CONFIG <cr> TERM <cr> INT BRI0 <cr> PPP AUTHENTICATION PAP <cr> [Ctrl] Z
WR T
NB. Section 1 step 3 has already set the passwords as PASSWORD
in readiness for PAP to be enabled.
Step 2: Enable PAP on the OfficeConnect™ Remote router:
Type the following: CO AUTH <cr>
ADD <cr> ADD PPP AUTH TABLE ENTRY Interface : CENTRAL Auth Class : PAP Local ID : REMOTE Local PW : PASSWORD Remote ID : CENTRAL Remote PW : PASSWORD
Enter the CO IS NU screen, EDIT the entry for CENTRAL and set
PPP AUTHENTICATION to PAP.
SECTION 3: ENABLE MULTILINK PPP (MP)
Step 1: Enable MP on the cisco.
Type the following: CONFIG <cr> TERM <cr> INT BRI0 <cr> PPP MULTILINK <cr> [Ctrl] Z
WR T
Step 2: Enable PPP on the OfficeConnect™ Remote.
Type the following:
Enter the CO IS NU screen, EDIT the entry for CENTRAL and set
PPP MP to ENABLE. CO PO <cr>
EDIT both ISDN ports, setting DEMAND to ENABLED and customizing
thresholds.
This configuration is for a remote site workstation on the
OfficeConnect™ Remote LAN to connect to a Novell server at
the Central Cisco LAN. A Pseudo IPX address needs to be used for
the OfficeConnect™ Remote LAN port a pseudo ISDN IPX network.
Step 1: Enable IPX routing on the Cisco 2500
Type the following: CONFIG <cr> TERM <cr> IPX ROUTING DIALER-LIST 1 PROTOCOL IPX PERMIT INT E0 IPX NETWORK xxxxxxxx ENCAPSULATION SAP BROADCAST INT BRI0 IPX NETWORK yyyyyyyy DIALER MAP IPX yyyyyyyy.zzzz.zzzz.zzzz NAME REMOTE nnnnnnn [Ctrl] Z
WR T (xxxxxxxx = Local IPX network number) (yyyyyyyy = ISDN IPX network number) (zzz.zzz.zzz.zzz = MAC address of OfficeConnect™ Remote)
(nnnnnnn = ISDN number of OfficeConnect™ Remote)
NB. ENCAPSULATION SAP sets the Cisco LAN port to Novell 802.2
Step 2: Enable IPX routing on the OfficeConnect™ Remote:
Type the following: CO PO <cr> ED <cr> Set local IPX network address and frame type.
CO IS NU <cr>
Edit the entry for CENTRAL and set the ISDN IPX network address.
CO BR PA <cr>
Enable Learn Novell RIP/SAP CO RO PA
Enable IPX ROUTING Bring up a manual call and wait for two minutes. Drop manual call
CO BR PA
Disable Learn Novell RIP/SAP
