Title: Example of DECbrouter90 V10.x CLNS (OSI) over Frame-Relay subinterfaces Product: DECbrouter90 V10.x Question: How do I configure the DECbrouter 90 to route CLNS over Frame-Relay Subinterfaces? Solution: This is an example of configuring CLNS or OSI routing over Frame-Relay subinterfaces with V10.x of the DECbrouter90 code. This example is for a level 2 connection across the WAN circuit. ------------------ | | | Frame-Relay | | cloud | | ----------- | | | | | | | | | ------------------ DCE | | DCE DLCI #101 | | DLCI #100 | | / \ / \ / \ / \ DTE / \ DTE --------- --------- | S0 | | S0 | | BRUTK | | BRUTL | | E0 | | E0 | --------- --------- Area 49.0004. | | Area 49.0003. --------- --------- BRUTK#show config version 10.0 hostname BRUTK ! clns routing ! !
