Configure the Layer 3 VPN export policy.
12.
If the Layer 2 virtual circuit (VC) is primary, the corresponding provider edge (PE)
routing device advertises the attachment circuit's (AC's) subnet with the higher
local preference. All aggregation PE devices initially advertise the AC's subnet with
the same local preference.
This routing policy allows a higher local preference value to be advertised if the
Layer 2 VC is active.
