[j-nsp] QFX5100 question

[Giuliano Medalha]

Joe,

Starting with 14.1X53-D10, QFX5100 supports L2VPN, but only the Martini
draft(LDP based), not Kompella(BGP based).

See the release notes:

Ethernet-over-MPLS (L2 circuit) (QFX5100)—Starting with Junos OS Release
14.1X53-D10, Ethernet-over-MPLS is supported on QFX5100 switches.


Ethernet-over-MPLS enables you to send Layer 2 Ethernet frames
transparently over an MPLS cloud. Ethernet-over-MPLS uses a tunneling
mechanism for Ethernet traffic through an MPLS-enabled Layer 3 core. It
encapsulates Ethernet protocol data units (PDUs) inside MPLS packets and
forwards the packets, using label stacking, across the MPLS network.


QFX5100 is a very good machine, with a lot of new features and good
performance, but you need to take care about the new CLI (L2NG) and how to
configure things (qinq for instance is different from EX).


I think that, if the actual implementation of L2VPN feature can support
your network, and you SE helps you and your tem with the correct scripts or
the correct way to configure (testing before) ... you will NOT have any
problems to buy it and to deploly it.


Att,


Giuliano
