Hi, I have forwarding problem with frame relay PVCs. I need to do local switching between 2 FR PVCs. The configurations seem to be correct and everything is "up" but no actual traffic is switched. I tried with Junos versions 7.4R2.6 and 8.1R1.5.The topology is:
|CE1(edge-a1)|---------|PE1(edge-a1)|------------|CE2(edge-a2)| e1-2/0/1.20-------e1-2/0/0.20|ds-2/0/4.20--------ds-2/0/4.20 192.168.30.2/24------------ccc-------------------192.168.30.1/30 And the configurations: CE2: [EMAIL PROTECTED] show interfaces ds-2/0/4:1 dce; encapsulation flexible-frame-relay; lmi { lmi-type ansi; } unit 20 { point-to-point; dlci 20; family inet { address 192.168.30.1/24; } } CE1: [EMAIL PROTECTED] show interfaces e1-2/0/1 description FR_PAC1; dce; encapsulation flexible-frame-relay; lmi { lmi-type itu; } unit 20 { dlci 20; family inet { address 192.168.30.2/24; } } PE1: [EMAIL PROTECTED] show interfaces e1-2/0/0 description FR_to_PAC1; encapsulation flexible-frame-relay; lmi { lmi-type itu; } unit 20 { encapsulation frame-relay-ccc; point-to-point; dlci 20; } [EMAIL PROTECTED]> show interfaces ds-2/0/4:1 encapsulation flexible-frame-relay; lmi { lmi-type ansi; } unit 20 { encapsulation frame-relay-ccc; point-to-point; dlci 20; } I configured first the local switching as l2circuit: [EMAIL PROTECTED]> show configuration protocols l2circuit local-switching interface e1-2/0/0.20 { end-interface { interface ds-2/0/4:1.20; } } [EMAIL PROTECTED]> show l2circuit connections interface e1-2/0/0.20 extensive Layer-2 Circuit Connections: Legend for connection status (St) EI -- encapsulation invalid NP -- interface h/w not present MM -- mtu mismatch Dn -- down EM -- encapsulation mismatch VC-Dn -- Virtual circuit Down CM -- control-word mismatch Up -- operational VM -- vlan id mismatch CF -- Call admission control failure OL -- no outgoing label XX -- unknown NC -- intf encaps not CCC/TCC CB -- rcvd cell-bundle size bad Legend for interface status Up -- operational Dn -- down Local Switch e1-2/0/0.20 Interface Type St Time last up # Up trans e1-2/0/0.20(vc 0) _* loc Up*_ Mar 12 12:02:49 2007 1 Local interface: e1-2/0/0.20, _*Status: Up*_, Encapsulation: FRAME RELAY Local interface: ds-2/0/4:1.20, _*Status: Up*_, Encapsulation: FRAME RELAY Time Event Interface/Lbl/PE Mar 12 12:02:49 2007 status update timer Mar 12 12:02:49 2007 status update timer Mar 12 12:02:48 2007 rmt intf up ds-2/0/4:1.20 Mar 12 12:02:48 2007 loc intf up e1-2/0/0.20 Mar 12 12:02:47 2007 rmt intf up e1-2/0/0.20 Mar 12 12:02:47 2007 loc intf up ds-2/0/4:1.20 I have pings running from CE1 to CE2 and viceversa, the interfaces that are part of local switch have input traffic but don't have output: [EMAIL PROTECTED]> show interfaces ds-2/0/4:1.20 Logical interface ds-2/0/4:1.20 (Index 131) (SNMP ifIndex 151) Flags: Point-To-Point SNMP-Traps Encapsulation: FR-CCC Input packets : 225 Output packets: 0 Protocol ccc, MTU: 1504 Flags: None DLCI 20 Flags: Active, DCE-Configured Total down time: 0 sec, Last down: Never _*Input packets : 225 *_ _*Output packets: 0 *_ [EMAIL PROTECTED]> show interfaces e1-2/0/0.20 Logical interface e1-2/0/0.20 (Index 123) (SNMP ifIndex 134) Flags: Point-To-Point SNMP-Traps Encapsulation: FR-CCC Bandwidth: 1984kbps Input packets : 86 Output packets: 0 Protocol ccc, MTU: 1504 Flags: None DLCI 20 Flags: Active, DCE-Configured Total down time: 0 sec, Last down: Never _* Input packets : 86 *_ _* Output packets: 0*_ I configured traceoptions with flag "all": [EMAIL PROTECTED] run show log fr.txt Mar 12 12:15:10 edge-a1-RE0 clear-log[4510]: logfile cleared Mar 12 12:15:17.246187 intf e1-2/0/0.20 (local switching), updated from configuration Mar 12 12:15:17.246334 intf ds-2/0/4:1.20 (local switching), updated from configuration Mar 12 12:15:17.457040 vc_iflchange intf ds-2/0/4:1.20 Mar 12 12:15:17.457155 vc_iflchange intf e1-2/0/0.20 Mar 12 12:15:17.459531 vc_ifachange : Triggering VC status update timer for intf e1-2/0/0.20 Mar 12 12:15:17.459549 Triggering VC status update timer for intf e1-2/0/0.20 Mar 12 12:15:17.459574 vc_ifachange: vc (Neighbor : local, VC-ID : 0), ifl e1-2/0/0.20: status intf Up -> intf Up Mar 12 12:15:17.459805 vc_ifachange : Triggering VC status update timer for intf ds-2/0/4:1.20 Mar 12 12:15:17.459811 Triggering VC status update timer for intf ds-2/0/4:1.20 Mar 12 12:15:17.459820 vc_ifachange: vc (Neighbor : local, VC-ID : 0), ifl ds-2/0/4:1.20: status intf Up -> intf Up Mar 12 12:15:17.517984 Recomputing the status of the VC for interface : e1-2/0/0.20 Mar 12 12:15:17.518032 Recomputing the status of the VC for interface : ds-2/0/4:1.20 I tried with following configuration but again no success: [EMAIL PROTECTED] show protocols connections interface-switch fr { interface e1-2/0/0.20; interface ds-2/0/4:1.20; } Does anybody have any clue what may be the problem? Is it a bug or I'm missing something? /Best regards, Angel Bardarov Senior Specialist Backbone Networks Fixed Networks Architecture and Engineering Department Bulgarian Telecommunications Company Plc.
