6 routers connected as shown in attached scheme. Router 1, Router 2, Router 3 and Router 4 belong to AS 100. OSPF protocol using as IGP. R1 and R3 service as PE devices. VPN instance applied on R1 and R3, R2 and R4 are P devices. R0 and R5 service as CE devices. OSPF protocol is used to exchange routes between PEs and CEs. CEs can communicate with each other. Normally, traffic between R0 and R5 are transferring through MPLS domain. When failure occurs, traffic between R0 and R5 can be transferred from the backdoor path (SHAM link is applied between R1 and R3, backdoor is link between R0 and R5). Main TE tunnel applied on R1-PE to R3-PE. VPN traffic is transferring through this TE tunnel. Signal protocol chooses RSVP. Bypass tunnel established through R1-R2-R4-R3 MPLS TE was debugged using manual 31162169-VRP Operation Manual MPLS Volume (VRP5 .30). Th econfiguration files is in attached files.
Bypass tunnel is not work correctly and in case then link between R1 and R3 is broken, the both tunnels stands in down state. Then both of them became in to up state using LSP through R1-R2-R4-R3.
Bypass tunnel setting LSP is same with primary tunnel. I tried to find how can I set LSP for each tunnel manually. I've found it.
This isn't correct work of bypass tunnel. Bypass tunnel should have different direction from primary, and not brakes in case described in Alarm information.
Need to create explicit path list and bind them to tunnel intefacу current configuration using commands shown in attached file: "additional configuration.rar".
