Configuring ARP direct route

Overview

The ARP direct route advertisement feature advertises host routes instead of advertising the network

route. This feature is typically configured on PE-aggs to advertise host routes to the connected PEs

in the L3VPN.

Figure 10

shows a typical application scenario where the PE in the L3VPN has ECMP routes

destined to a base station in the L2VPN. Traffic from the PE in the L3VPN to the base station can be

load shared by PE-agg 1 and PE-agg 2. If PE-agg 1 fails, the PE uses the host route through PE-agg

2 to forward traffic.
