ASR 9000 IGP/BGP FC Feature Highlights

 ISIS/OSPF is optimized for FC by default

 IGP Prefix prioritization  guarantee important prefixes get converged at first

 IP FRR  <50msec IP fast reroute without using MPLS TE/FRR

 BGP PIC core  Prefix independent BGP fast convergence for core failure

 BGP PIC Edge  Prefix independent BGP fast convergence for edge failure

 MPLS TE/FRR  <50msec link and node protection, prefix independent

 Link bundle  <50msec link protection for thousands of sub-interfaces per

bundle port

 Distributed BFD  1K session per LC, 8K per system with 150 msec hello

interval. Minimal hello interval can be as low as 15msec; BFD support IGP, BGP,

static router, PIM, HSRP/VRRP, MPLS TE



Multicast only FRR (MoFRR) 

–50msec IPv4 multicast convergence for IPTV Video service

–End-to-End 50msec path protection by using data plane failure detection

–

Operational simple without using P2MP TE-FRR
