[j-nsp] Transit composite next hops

[Luis Balbinot]

Hi.

I was reading about composite chained next hops and it was not clear to me
whether or not MX routers support them for transit traffic. According to
the doc bellow it's only a QFX10k/PTX thing:

https://www.juniper.net/documentation/en_US/junos/topics/reference/configuration-statement/transit-edit-routing-options-chained.html

But there are some contradictions like this document:

https://www.juniper.net/documentation/en_US/junos/topics/concept/mpls-vpns-chained-composite-next-hops.html

Which is correct? Juniper docs on this subject, specially transit CNHs, are
very superficial. The MX Series book does not mention it and the MPLS in
the SDN Era only explains how the ingress CNHs work.

Thanks.

Luis
