Disclaimer, I work for cisco and was involved in the idea, design and implementation of BGP PIC Edge, though here I speak only for myself and not my employer.
>From the "Example: Configuring MPLS Egress Protection for Layer 3 VPN Services" of http://www.juniper.net/techpubs/en_US/junos12.2/information-products/topic-collections/config-guide-vpns/config-guide-vpns.pdf It looks like this is a very different thing than BGP PIC Edge, it require manual configuration and designated PLRs. None of that is required with BGP PIC Edge, which on a per prefix basis will on the ingreess PEs automatically calculate the primary and repair egress PE, and setup forwarding structures allowing Prefix Independent (constant time) Convergence of all affected prefixes when the loopback of the primary egress PE is withdrawn from the IGP. Additionally BGP PIC Edge also provides Prefix Independent Convergence in the case of a PE-CE link failure, or CE node failure, where the egress PE will redirect traffic to an backup PE/CE, again the backup PE/CE is automatically pre-calculated on a per prefix basis, so you can have CE1 be the primary for say 10k prefixes, where CE2 is the backup for 5k of them and CE3 for the remaining 5k. Lastly, this all works for prefixes in a L3 VPN or in the global routing table, as long as the IGP routes are labeled. /Jesper On Tue, Jan 01, 2013 at 12:04:15AM -0500, Phil Bedard wrote: > 11.4R3 I believe.
