[j-nsp] multiple bgp routing-instances on one router

[Rafal Szarecki (WA/EPO)]

Hi all,


It will not work as original request specified. This is because bot routing instances will export prefixes from  partial.inet.0 (first on the list)

I suggest to create: rib-group common-2  import-rib [ integral.inet.0 partial.inet.0] and use them in Integral routing instance.

Other notes:

- Because bot RIBs will contain exactly the same conten, what is a reason to keep multiple identical tables?
- If you do not need mpls, then you can use instance-type virtual-router. Then You not need to configute RT, RD.

Dimitriy, let me know more about application for this multiple routing tables, maybe ther will be more simple solution.
