there is no interface in PIPPO routing-instance; therefore the ping
fails even if I don't specify the source address:
rc2# run ping 1.1.1.2 routing-instance PIPPO
PING 1.1.1.2 (1.1.1.2): 56 data bytes
ping: sendto: Can't assign requested address
The idea was to source the bgp session in routing-instance PIPPO from
the same interface 1.1.1.1 that is in the global instance.
Thanks,
bit.

can use a source address that is native to the routing-instance, ie a loopback
interface declared in the routing-instance.
run ping 1.1.1.2 routing-instance PIPPO

Objet : Re: [j-nsp] how to populate a forwarding routing-instance
Hi Martin,
indeed with rib-group I can import in the routing-instance PIPPO the connected and local routes, but still BGP doesn't come up because I think the process can not bind to the address of the local interface which is still part of a different routing-instance, the default one.
For the same reason while also ping fails:
rc2# run ping 1.1.1.2 source 1.1.1.1 routing-instance PIPPO PING 1.1.1.2
(1.1.1.2): 56 data bytes
ping: sendto: Can't assign requested address
Thanks,
bit.

Indeed, the interfaces routes from inet.0 are unknown to your new routing-instance which is as expected. You can use rib-groups (routing table groups) to import the connected interface routes into your new routing-instance.
I haven't tested the exact config below, but the concept is as follows:
# define that interface routes should be processed by a new rib-group
routing-options {
interface-routes {
rib-group inet connected;
}
}
# define that the routes matching the new rib-groups are copied from inet.0 to
your new routing-instance
rib-groups connected {
import-rib [ inet.0 PIPPO.0 ];
}
}
You may call that exporting routes but JUNOS sees it as importing routes. Guess it depends on the perspective.
When you do a show you after the commit, the connected routes from inet.0 should show up in PIPPO.0
with "Primary Routing Table inet.0" if you do a "show route detail". Same
route, but in a different table.
Cheers

juniper-nsp@puck.nether.net Objet : Re: [j-nsp] how to populate a
forwarding routing-instance
Martin,
as a 'virtual-router' the protocol configuration commits correctly but still I
have a little problem:
to setup the BGP session, I need the connecting interface in the
routing-instance PIPPO as well as in the global routing-instance for normal
forwarding and this is not accepted :-( any idea how to work around that?
Thanks,
bit.

Hello
Try "instance-type virtual-router" instead of "instance-type forwarding" to be able to
support routing protocols - this way the commit should work. "instance-type virtual-router" also
support filter-based forwarding.
Cheers

how to populate a forwarding routing-instance
Experts,
I want to configure FilterBasedForwarding and so I need a routing-instance of
type forwarding.
I have no issue to populate the routing-instance with static routes; but in
reality I would like to use bgp to populate it; and this doesn't commit.
Is it possible to use bgp for that? If not, any other way to achieve FBF using
a routing protocol rather than static for the alternate forwarding?
Thanks,
bit.
