Two routers are connected by E1 using serial interfaces. Two or more channel-sets are created on the E1 controllers which connect routers. MPLS and BGP configured. MPLS LDP peers and BGP peers are established successfully, but MPLS LSP are not established (0 records).
Check, if ALL serial interfaces created by E1 controller have MPLS LDP ENABLE. If some of them don't have MPLS LDP ENABLE - enable it.
Several channel-sets on the E1 controller create the same number of serial interfaces. Possible reason of LSP problem is that on some of serial interfaces of this E1 controller isn't enabled MPLS LDP.
For example we have 2 channel-sets on controller E1 1/1/0. It will create 2 serial interfaces (1/1/0:0 and 1/1/0:1). MPLS LDP ENABLE must be done on both of them (not only one) even if MPLS BGP VPN should run on only one of them.
Summary: possible reason - not all serial interfaces of the E1 controller have MPLS LDP ENABLE.
