[j-nsp] dynamic profile: dynamic vlan and routing instance creation

[Harvey Young]

Hello,

I am trying to create a dynamic vlan and routing instance via dynamic
profile. Essentially I am trying to create a subscriber where the vlan and
routing instance will be created on the fly.

i.e. sub-1 gets dynamically configured for 1/1/1.2 "vid 2" and routing
instance X is created dynamically and associated.

The following link seems to imply this is possible:

http://www.juniper.net/techpubs/en_US/junos12.1/topics/task/configuration/vlan-dynamic-profile-routing-instances.html

However the MX running 12.1 rejects the radius message containing the
routing instance that I want to create and returns. "Routing instance does
not exist"

Is this supported? Or is it a typo in the JNPR document and the routing
instance needs to be pre-configured on the system. Hence, only the vlan is
dynamically created and associated to a pre-configured RI?

Thanks....
