Phil,
 Thanks, This is an interesting idea.  Not something I had though of. Seams like a logical solution though.

Ill take a look at it.

Thanks

Is it all one OSPF area or is the CMTS in an area other than 0? If the
MX480 is an ABR you can restrict the OSPF routes and originate them on
the MX480 as BGP instead using aggregate statements.

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.

James
