[j-nsp] understanding interface encapsulation, family ... and more

[Aaron]

Hi all,

 

I'm a cisco guy coming into the juniper world.  I'm trying to understand all
these different interface family and encapsulation options.. And the
difference seen between my ACX5048 and my MX104.

 

I'm having trouble comparing this to something I've done in the cisco world.
Does anyone have a website link or anything that would help me understand
the different uses and scenarios why I would use these ? (junos4ios book has
a little bit but not much info).  Or perhaps you can explain it to me.

 

I run an MPLS network of Cisco ASR9000's, ME3600's and ASR901's and am
embarking on acquiring several ACX5048.  I do lots of MPLS L3VPN's and MEF
ELINE, ELAN and ETREE services, via manual l2vpn pw's and bgp auto vpls
elan's.. also do single and dual tag operations of pushing and popping 

 

.so I really need to know what options (encaps and families) I will probably
be using for the things I mentioned above.

 

Is there a good book/class for this SP Layer 2 understanding of Junos ?  Is
the class JSPX (Juniper Service Provider Switching) good for things like
this ?
