OK, thanks so much, one question:
In a vrf configuration i already have an interface with a default gateway of the vrf , then i don't need configure a loopback for each vrf, see the configuration:
instance-type virtual-router;
interface irb.2442;
interface irb.2444; <<<<<<<<<<<<<<
protocols {
ospf {
export training_ospf2fw;
area 0.0.0.0 {
interface irb.2444;
interface irb.2442;
core01> show configuration interfaces irb.2444
family inet {
address 10.236.26.1/24; <<<< this is a default gateway ( core01 )
From a remote server of this routing-instance:
Server#ssh Y9CB9N@10.252.26.1
password:
--- JUNOS 14.1R3.5 built 2014-11-13 10:59:26 UTC
{master:member0-re0}
core01>
I want filter this ssh access, when in routing-instance , the default gateway is own device ( core01 ) . So, with your previous configuration I don't need configure a loopback for each routing-instance, because i already have an IRB interface ( with default gateway ) .
Thanks a lot.
