Re: [j-nsp] Traffic balancing over LSPs
You could use the install command under the LSP on the ingress PE (which is somewhat manual), or you could change from OSPF to BGP on the CMTS... -Original Message- From: juniper-nsp-boun...@puck.nether.net [mailto:juniper-nsp-boun...@puck.nether.net] On Behalf Of James Ashton Sent: Thursday, January 17, 2013 5:07 PM To: juniper-nsp@puck.nether.net Subject: [j-nsp] Traffic balancing over LSPs I have an interesting situation that has me stumped for the moment.

Re: [j-nsp] Traffic balancing over LSPs
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.

Re: [j-nsp] Traffic balancing over LSPs
The dest prefix needs to resolve over the LSP. IGP short-cuts is an easy way to make that happen and should work for you but I see you tried that already and had some issue. I would suggest trying to understand why igp shortcuts breaks something else. You can also use a rib-group on the LSP head-end to populate inet3 as needed. -cb On Jan 18, 2013, at 10:11 AM, James Ashton wrote: All, Just to clarify a few things, The destination is not in inet.3.

Re: [j-nsp] Traffic balancing over LSPs
This is the way we (and many others) run our core network, there are very few IGP routes other than loopbacks and interface addresses. If you need an example let me know but the main command is area-range x.x.x.x/x restrict.
