Chapter 43 Configuring VRF-lite
Configuring VRF-lite for IPv4
Configuring the User Interface for ARP
To configure VRF-aware services for ARP, perform this task:
Configuring Per-VRF for Servers
The per-VRF for servers feature enables you to configure per-virtual route forwarding
(per-VRF) authentication, authorization, and accounting (AAA) on servers.
Before configuring per-VRF on a server, you must have configured AAA and a server group.
You can create the VRF routing table (shown in Steps 3 and 4) and configure the interface (Steps 6, 7,
and 8). The actual configuration of per-VRF on a server is done in Steps 10 through 13.
