Configuring the R2CP Radio-to-Router Protocol
46
A virtual channel group is a collection of virtual channels. Each radio can have only one
virtual channel group assigned uniquely. If you have more than one radio connected to
the router, you must have one virtual channel group for each local radio-to-router pair.
Although a virtual channel group is assigned to a logical interface, a virtual channel is not
the same as a logical interface. The only features supported on a virtual channel are
queuing, packet scheduling, and accounting. Rewrite rules and routing protocols apply
to the entire logical interface.
All nodes in the R2CP network are in a broadcast LAN. The point-to-multipoint over LAN
protocol supports advertising different bandwidth information for neighbors on a
broadcast link. The network link is a point-to-multipoint link in the OSPFv3 link state
database, which uses existing OSPF neighbor discovery to provide automatic discovery
without configuration. It enables each node to advertise a different metric to every other
node in the network to accurately represent the cost of communication. The
p2mp-over-lan interface type under the OSPFv3 interface configuration enables you to
configure the interface. OSPFv3 then uses LAN procedures for neighbor discovery and
flooding, but represents the interface as point-to-multipoint in the link state database.
The interface type and router LSA are available under the following hierarchies:
[protocols ospf3 area area-id interface interface-name]
[routing-instances routing-instances-name protocols ospf3 area area-id interface
interface-name]
For example:
protocols {
ospf3 {
area 0.0.0.0 {
interface ge-0/0/2.0 {
interface-type p2mp-over-lan;
}
}
}
}

The following example creates four logical interfaces on ge-0/0/2, using unit 52 for
R2CP control messages and units 101-193 for data traffic. The per-unit-scheduler
statement is required for R2CP.
interfaces {
ge-0/0/2 {
per-unit-scheduler;
vlan-tagging;
