[c-nsp] TE config help

[mb2 at os.datafx.com.au]

Quoting mb2 at os.datafx.com.au:

> Hi,
>
> We currently have dual links between our core routers (7206VXRs) -
> Primary being ATM, and secondary being Ethernet - At present, Ethernet
> is only used if ATM fails(This is achieved via OSPF)....we presently
> only have mpls enabled on the ATM links.
>
> We are wanting to make more efficient use of the backup ethernet
> links(As they are expensive)....hoping that TE is the correct(best
> practice) option.
>
> Our current bandwidth is as follows:
>
> ATM - 8Mb Ethernet - 4Mb
>
> Our goal is to (hopefully) have a total of 12Mb bandwidth available for
> use(i.e. Load-share over both the ATM+Ethernet links)......Is FRR
> necessary in what we are wanting to achieve?
>
> Proposed config for one of the Core routers...
