[j-nsp] Route Import/Export vs BGP-over-LT

[Lawrence Wong]

Hi everyone,

In a scenario whereby there are multiple routing-instances (virtual routers) on 
the same box, I guess I can either:

a. perform route import/export between the routing-instances

or

b. use a LT tunnel to "tie" the routing-instances together and then run BGP 
between the routing-instances


Does anyone have any experience or insight to share? I'm wondering how the 
reliability, performance, memory utilisation, caveats will be like and if there 
is any best practise?


Many thanks!
