[j-nsp] Traffic balancing over LSPs

[James Ashton]

I have an interesting situation that has me stumped for the moment.

I have an OSPF speaking device (ARRIS CMTS) hanging off from an EX Switch. 
That switch is uplinked to an MX480 which is part of the network core. It has several paths into it from rest of the network.
>From several major traffic centers in the network I have 3 LSPs created to the MX480.
I am running "mpls traffic-engineering mpls-forwarding" throughout the network.

As the end users hanging off the CMTS are advertised onto the network via OSPF, and I cannot terminate LSPs on the CMTS, the traffic to these users is not being forwarded over the LSPs.
I have tested enabling "ospf traffic-engineering shortcuts" but that is breaking several paths in the network to legacy areas with odd configs. 

My question is basically, how can I get this traffic into these LSPs in way that is more manageable at scale than a pile of static routes.


I hope the above is clear,  I am low on Caffeine at the moment.

Thank you in  advance for any help/ideas.
