BGP PIC—This release introduces support for BGP Prefix-Independent Convergence (PIC). This
•
feature improves BGP convergence after a network failure. This convergence is applicable to both
core and edge failures and can be used in both IP and MPLS networks. The BGP PIC Edge for IP
and MPLS-VPN feature creates and stores a backup/alternate path in the routing information base
(RIB), forwarding information base (FIB), and Cisco Express Forwarding so that when a failure is
detected, the backup/alternate path can immediately take over, thus enabling fast failover. For more
information, see

xe-3s-asr903-book.html
VPLS BGP Signaling—This release introduces support for VPLS BGP Signaling. The two primary
•
functions of the Virtual Private LAN Service (VPLS) control plane are autodiscovery and signaling.
The VPLS BGP Signaling feature enables you to use BGP as both an autodiscovery and a signaling
protocol for VPLS. For more information, see
