[c-nsp] communication between different vrfs on same PE

[Manoj koshti]

Hi Raj,
 
 Do you work for VSNL ? This is part of overlapping VPN ,You can import the route-target to install the route from other VPN vrf table. Juniper use rib-group to do this .

Dear Oliver,
Thanks for ur reply ,
Does this means that import/export route-targets on same PE can be achieved
without MP-BGP sessions 
If you can explain in detail how it works then it would be really gr8

Thanks in advance !!!

use appropriate route-target export/import statements to achieve this.
example

ip vrf vrf-red
rd 1:1
route-target both 1:1
route-target import 1:2
!
ip vrf vrf-blue
rd 1:2
route-target both 1:2
route-target import 1:1

This way "red" will import "blue" routes (and vice versa), so both VRFs
will be able to communicate.
