Juniper JUNOSE 11.0.X MULTICAST ROUTING, Configuration Manual

The route-download server accepts downloaded routes in either the Framed-Route
attribute (RADIUS attribute 22) or the Cisco-AVpair attribute (Cisco VSA 26-1).
Downloaded Route Format Examples
Framed-Route (RADIUS attribute 22)
NAS-1 Password = “14raddlsvr” User-Service-Type = Outbound-User
Framed-Route = “192.168.3.0 255.255.255.0 null0”
Framed-Route = “vrf vrfboston 192.168.1.0/24 null 0 0 tag 6”
Framed-Route = “vir host1 vrf vrfsunny 192.168.0.0/16 null0 0 tag 8”
Cisco-AVPair (Cisco VSA 26-1)
NAS-1 Password = “14raddlsvr” User-Service-Type = Outbound-User
cisco-avpair = “ip:route = 192.168.3.0 255.255.255.0 null0”
cisco-avpair = “ip:route = vrf vrfboston 192.168.1.0/24 null 0 0 tag 6”
cisco-avpair = “ip:route = vir host1 vrf vrfsunny 192.168.0.0/16 null0 0 tag 8”
NOTE: The prefix-mask entry in downloaded routes can be in the form of prefix
length, prefix mask, or prefix. If prefix is used, the mask is determined by the IP
address class of the prefix.
How the Route-Download Server Downloads Routes
The route-download server starts the initial route-download operation (for example,
after a system reboot or the first time the route-download server is enabled) as soon
as IP is established in the virtual router in which the download is performed. After
the initial route-download process is established, the router repeats the route download
operation based on either the default download schedule or the schedule you specify.
You can also initiate an immediate route download at any time.
The RADIUS route-download server downloads routes in two stages—first, all routes
are downloaded from the RADIUS server to the router’s download database and
examined for errors. Next, the router updates the routing table with the new routes,
using the following guidelines:
■
Adds all downloaded routes that are not already installed in the routing table
■
Does not add downloaded routes that are already installed in the routing table
■
Deletes routes from the routing table that do not appear in the newly downloaded
group
Configuring the Route-Download Server to Download Routes
When you configure the E Series router as a route-download server, you specify the
RADIUS server that you want to download the routes to your router. You can also
modify the route-download server’s default configuration parameters, such as when
