Re: Practicing DLSw
First check if the peers are up/connect via sh dlsw peer . If not check the IP connectivity by doing an 'extended ping' between 192.188.1.1 and 192.188.2.1 . This should be succesfull if not == routing issue . Ofcourse you could first look in the routing table to see if you can reach the networks in question . This saves you the pinging :) Second the netbios stations should be connected on eth0 on both r0 and r5 . Netbios means native netbios , NOT netbios encapsulated in IP . Thirth , check the reachabily by doing sh dlsw reach . You should see the netbios names listed in the cache . If this is all good and still does not work -- play around with the debugs and see if it all goes as expected( debug dlsw ) . If it is working , then still play around with the debugs and see how a working connection looks like . flem --- Jairo Nuvan [EMAIL PROTECTED] wrote: OK R2 .../..\ ../\ --R0-R1R4--R5-- ..\/ ...\../ R3 Thanks Jairo --Original Message-- From: Flem [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: August 30, 2000 9:50:36 PM GMT Subject: Re: Practicing DLSw It is not a requirement that the DLSw local and remote peer IP addresses are those of a physical interface .

RE: Practicing DLSw
i made a mistake, with /30 subnet mask you can have max 2 host on network so eth1-R0 10.10.66.1 ethx-R1 10.10.66.2 there isn't space for a PC. so i think you have connected the PC on eth0 on R0 but eth0 don't have an IP address so you can't have IP connectivity on eth0 and you can't ping trought this interface. Remeber that dlsw make incapsulation of SNA packet (802.3 SSAP 04 - ?? i forgot the range) and Netbios (SSAP F0 )and don't do encapsulation for IP (SSAP AA and SNAP 0x800). the same for R5 sorry for mistake, hope i'm right now.
