from inet3.0, you only have one interface for the route you mentioned. By default, I think it is not load sharing for multiple connections. You may check that you enabled multi-path from OSPF.
If I were you, I would like to add AS PIC or something, and make 3 T1s as MLPPP bundled. So I can treat all 3 T1 connections as single connection from MPLS viewpoint.

[EMAIL PROTECTED] Amos Rosenboim <[EMAIL PROTECTED]> Sent by: [EMAIL PROTECTED] 02/02/2007 02:50 PM To [email protected] cc Fax to Subject [j-nsp] RSVP/MPLS question Hi, I'm trying to enable MPLS in a small service provider network. The network consists of 4 M10i routers, and 1 ERX router. The ERX is out of the scope for the moment, and first stage was to configure RSVP and MPLS on the M series routers, and to create a full mesh of LSP. The topology is described in the below drawing: R1-----3 X E1------R2------Ethernet (VLAN on a GigE interface)------ R3----------T3------------R4 All is working well between R4, R3, and R2. However, all LSP from R1, except for the one to R2 are down. The failed LSP at R1 shows: CSPF failed: no route toward 217.69.0.4[4873 times] While: [EMAIL PROTECTED]> show route 217.69.0.4 inet.0: 126 destinations, 131 routes (126 active, 0 holddown, 0 hidden) + = Active Route, - = Last Active, * = Both 217.69.0.4/32 *[OSPF/150] 1d 11:16:33, metric 5, tag 0 via e1-1/3/0.0 > via e1-1/3/2.0 via e1-1/3/4.0 inet.3: 108 destinations, 109 routes (108 active, 0 holddown, 0 hidden) + = Active Route, - = Last Active, * = Both 217.69.0.4/32 *[OSPF/150] 1d 10:17:08, metric 5, tag 0 > via e1-1/3/0.0, label-switched-path To-ATH Also, RSVP is acting very strange over the 3 X E1 lines between R1 and R2. First, when we configured all 3 E1 for RSVP, only two neighbors came up. After few clear RSVP session commands the third neighbor came up. Then, there are only active RSVP sessions between R1 and R3 and R4, only with R2. Then we disabled RSVP on 2 of the E1 lines and stayed with just one, but R2 still showed 3 RSVP neighbors. Their idle time increase but they are staying "up" although RSVP is no longer configured on those interfaces. When tracing RSVP on R2 we also get: Feb 1 12:05:35.602215 RSVP error, send to DISABLED interface?

I'm suspecting it's either something with the 3 x E1 connection, or RSVP issue, but I can't really fix it. Any help will be welcomed.
