[j-nsp] Virtual route reflector physical layout

[raf]

Hi guys,

I got a couple of questions about the implementation of virtual route 
reflector. For now I think I will use vrr from juniper, but other soft 
can do the job and the question is general to out of path RRs.

While there are 'virtual' components, they can be physical connected 
anywhere in the network. But as a critical part of the network they have 
to be connected at the right place. In an ideal world I would take two 
dedicated hypervisors for them, and connect them redundantly to the core 
router (back to back). But this is not a very cheap solution.

Some questions :

- are the (v)RRs really have to be part of the IGP ? with two or more 
paths to the core ?
- are the (v)RRs really have to be physically connected to routers ?

I know that Mark have deploy cisco CSR1000v, and I am interested about 
details on his setup, but interested on other scenarios also :)

Thks.
