[j-nsp] vpls question

[james list]

I have a VPLS multi-homed environment with two MX routers (PE1 and PE2)
connected to a single ethernet switch (CE1). I have PE1 configured with
site-preference as "primary" and PE2 as "backup".


Behind the CE1 there is a router running OSPF with both MX (on irb
interface).


My goal is to have:

1)    Multihoming to prevent loops

2)    Let the router run two OSPF neighbor with both PE and not just one
with the primary PE.

I’m wondering if using:


set routing-instances XXXX protocols vpls connectivity-type irb


instead of the default (connectivity-type ce) could give me the option to
reach my goal number 2) and if I can introduce any drawback.


Or if there is another solution keeping 1).


I don’t have a lab to test…


Any help/feedback is really appreciated.


Greetings

James
