SUMMARY

When configuring the TP4 protocol over routers, if the router is capable of understanding the ES-IS protocol there is no need to specify static routes or default gateways. If the router doesn't understand the ES-IS protocol, you might need to add Static Routes to the OSIRTE file.

This file is located in your %windir%\system32\drivers\etc directory. The file includes comments on how to add routing table entries.

The following is a sample OSIRTE file.


;
;       Static Routing table entries use the format as follows:
;
;       NSAP:MAC/X.121 address:Priority:CardChoice
;
;       Where;
;       NSAP = The remote ES's NSAP you want to communicate with
;
;       MAC = The ethernet address and is always an Hex format
;
;       X.121 address must be encoded in hex as 703701020304..and so on
;
;       Priority =  0 or 1.
;
;       CardChoice = ndis device name. I know it is cumbersome
;       Use the System-CurrentControl-services-Isotp-Linkage->bind of RegDB
;       Key values as shown. (NOTE: Streams is omitted from ndis_dev name)
;
;       NO BLANK SPACES ALLOWED IN THESE ENTRIES
;       RemoteNSAP can be ASCII. A $ implies HEX encoding for 1st & 2nd
;       field.
;
;       Lets take an example. If you want to route a destination whose
;       NSAP is FIRSTPLACE on Etherlink 3 card to an IS system whose
;       MAC address is 010203040506 the entry would loook like
;
;       FIRSTPLACE:$010203040506:1:\Device\Elnk31
;
; The static routes are as defined below
;
; The 1st line is priority 0 route for NSAP 474747(hex)
; The 2nd line is alternate route for NSAP GEE ( hex:474747)
; Where as 2rd line is highest priority for NSAP GGG but on FDDI card.
; Now the card with subnet id = 0 will be the 1st one used.
;
;$474747:$112233445566:0:\Device\Elnk31
;GGG:$010203040506:1:\Device\Elnk31
;GGG:$010203040506:0:\Device\SkFddiFe2
