If Your Client routers support it, FREEK (acronym for Frame-Relay End-to-End Keepalive) may be what You are looking for... Cheers Alex

Guys....! I have got stuck in a issue regarding MPLS L2circuit (Martini). Here is my scenario, L2cct (Martini) has been configured between two MPLS Nodes. Client Site A is connected directly over E1 at MPLS Node (M10i) and Client Site B is connected to Frame Relay Switch (New Bridge 3600) over E1 where its DLCI sync. It then extended to second MPLS Node over FR-NNI (E1). Refer to below mention diagram, __ ____________________ | ( L2circuit Martini) | CE – FR Switch – (FR-NNI over E1) – M10i ------------------------- M10i – CE Client is UP and running successfully. ** *MPLS Node - B* *show interfaces ds-1/1/2:1.0 * Logical interface ds-1/1/2:1.0 (Index 121) (SNMP ifIndex 156) Description: *** Client X SITE B *** Flags: Point-To-Point SNMP-Traps Encapsulation: FR-CCC Input packets : 47743200 Output packets: 43623195 Protocol ccc, MTU: 1504 Flags: None *DLCI 152* * Flags: Active, DCE-Configured* Total down time: 53:49:06 sec, Last down: 01:34:06 ago Input packets : 47743200 Output packets: 43623195 *show l2circuit connections* Neighbor: A.B.C.D *Interface Type St Time last up # Up trans* *ds-1/1/2:1.0{vc 152) rmt Up Dec 26 08:32:09 2006 1* *Local interface: ds-1/1/2:1.0, Status: Up* , Encapsulation: FRAME RELAY Remote PE: W.X.Y.Z, Negotiated control-word: Yes (Null) Incoming label: 102320, Outgoing label: 155888 *MPLS Node - A* show interfaces e1-1/1/9.0 Logical interface e1-1/1/9.0 (Index 121) (SNMP ifIndex 152) Description: *** Client X SITE A *** Flags: Point-To-Point SNMP-Traps Encapsulation: FR-CCC Input packets : 477432 Output packets: 43623 Protocol ccc, MTU: 1504 Flags: None *DLCI 152* * Flags: Active, DCE-Configured* Total down time: 53:49:06 sec, Last down: 01:34:06 ago Input packets : 477432 Output packets: 43623 *show l2circuit connections* Neighbor: W.X.Y.Z *Interface Type St Time last up # Up trans* *e1-1/1/9.0{vc 152) rmt Up Dec 26 08:32:09 2006 1* *Local interface: e1-1/1/9.0, Status: Up, *Encapsulation: FRAME RELAY Remote PE: A.B.C.D, Negotiated control-word: Yes (Null) Incoming label: 102320, Outgoing label: 155888 *Problem:* When Client SITE B goes down (due to lastmile failure), FR Node make the DLCI inactive and signals to M10i to force the DLCI down. But at M10i only DLCI goes down not CCC which causes l2circuit to remain UP and SITE A get the L2circuit UP, if its other SITE is down. If client have a backup link between these sites than Site A router will not trigger for backup link. *MPLS Node - B* *show interfaces ds-1/1/2:1.0 * Logical interface ds-1/1/2:1.0 (Index 121) (SNMP ifIndex 156) Description: *** Client X SITE B *** Flags: Point-To-Point SNMP-Traps Encapsulation: FR-CCC Input packets : 47743200 Output packets: 43623195 Protocol ccc, MTU: 1504 Flags: None * DLCI 152* * Flags: Down, DCE-Configured* Total down time: 53:49:06 sec, Last down: 01:34:06 ago Input packets : 47743200 Output packets: 43623195 ** * * ** *show l2circuit connections* Neighbor: A.B.C.D *Interface Type St Time last up # Up trans* *ds-1/1/2:1.0{vc 152) rmt Up Dec 26 08:32:09 2006 1* *Local interface: ds-1/1/2:1.0, Status: Up* , Encapsulation: FRAME RELAY Remote PE: W.X.Y.Z, Negotiated control-word: Yes (Null) Incoming label: 102320, Outgoing label: 155888 *MPLS Node - A* *show interfaces e1-1/1/9.0* Logical interface e1-1/1/9.0 (Index 121) (SNMP ifIndex 152) Description: *** Client X SITE A *** Flags: Point-To-Point SNMP-Traps Encapsulation: FR-CCC Input packets : 477432 Output packets: 43623 Protocol ccc, MTU: 1504 Flags: None *DLCI 152* * Flags: Active, DCE-Configured* Total down time: 53:49:06 sec, Last down: 01:34:06 ago Input packets : 477432 Output packets: 43623 *show l2circuit connections* Neighbor: W.X.Y.Z *Interface Type St Time last up # Up trans* *e1-1/1/9.0{vc 152) rmt Up Dec 26 08:32:09 2006 1* *Local interface: e1-1/1/9.0, Status: Up* , Encapsulation: FRAME RELAY Remote PE: A.B.C.D, Negotiated control-word: Yes (Null) Incoming label: 102320, Outgoing label: 155888 My Question: *Why L2circuit is not down, if FR node signal to down the DLCI? This signal not causes CCC to down. or Is there any way to reflect DLCI down to far end CE? * _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
