Hi,

Please, I need your assistance of onconfiguring the vpn-instance.

I'm trying to isolate the management interface into a independent vpn instance for out-of-band management. But the configuration below doesn't achieve the goal. Though ping and access from the local subnet works, failed access the router from adifferent subnet. Also I've already added the default route to thevpn-instance but no success either.

#

ip vpn-instance mgmt-vpn

 ipv4-family

  route-distinguisher 100:1

  vpn-target 100:1 export-extcommunity

  vpn-target 100:1 import-extcommunity

#

ip route-static 0.0.0.0 0.0.0.0 vpn-instance mgmt-vpn x.x.x.x

#

interface GigabitEthernet0/0/1

 ip binding vpn-instance mgmt-vpn

 ip address x.x.x.y 255.255.255.0

 undo shutdown

#

Regards.

Hi,
The default route you configured is error.
The default route you posted will direct all the traffic to the mgmt-vpn, and, I think, which is not what you want, even the service might be impacted.
To bind the static route to the vpn-instance, please refer to the command below:
ip route-stat vpn-instance mgmt-vpn 0.0.0.0 0.0.0.0 x.x.x.x

It's really thanks.
BTW, I found that the route could be configure as "ip route-static vpn-instance mgmt-vpn 0.0.0.0 0.0.0.0 vpn-instance xxx". Does this static route guide the traffic in vpn-instance mgmt-vpn to vpn-instance xxx?
