Service provider style requires explicit configuration of each feature on the interface, and the bridge domains need to reference the interface.
Enterprise style does not require explicit configuration for each feature, which reduces the amount of configuration but also reduces the number of features.

Read moreThe underlying mechanism for the Aruba redundancy solution is the Virtual Router Redundancy Protocol (VRRP)
-If VRRP preemption is disabled (the default setting) and all controllers share the same priority, the first controller that comes up becomes the master.
OR
-If VRRP preemption is enabled and all controllers share the same priority, the controller with the highest IP address becomes the master.
Rib-groups simple example.
We created two routing instances: test1 and test2, each instances has one interface in it:
test1 - vlan.641: 172.16.10.1/24
test2 - vlan.642: 172.16.20.1/24
# show routing-instances
test1 {
instance-type virtual-router;
interface vlan.641;
}
test2 {
instance-type virtual-router;
interface vlan.642;
}
Routing table looks like this:

Continuing on the subject of confusing Junos features, I’d like to talk about RIB groups. When I started here at Juniper, I remember being utterly baffled by this feature and its use. RIB groups are confusing both because the official documentation is confusing, and because many people, trying to be helpful, say things that are entirely wrong. I do think there would have been an easier way to design this feature, but RIB groups are what we have, so that’s what I’ll talk about.
