BGP PIC is intended to improve network convergence which will safely allow for setting aggressive ICSR failure 
detection timers. 
configure 
   context context_name 
      service-redundancy-protocol 
         advertise-routes-in-standby-state [ hold-off-time hold-off-time ] 
reset-bfd-nbrs
 bfd-down-time ] 
         end 
Notes: 
 
 hold-off-time hold-off-time delays advertising the BGP routes until the timer expires. Specify hold-off-time in 
seconds as an integer from 1 to 300. 
 
 After resetting BFD, reset-bfd-nbrs bfd-down-time keeps the BFD sessions down for the configured number of 
milliseconds to improve network convergence. Specify bfd-down-time as an integer from 50 to 120000.  
Configurable BGP Route Advertisement Interval for ICSR 
By default, the MinRtAdvInterval is set for each peer with a value of 5 seconds for an iBGP peer and 30 seconds for an 
eBGP peer. An operator can use the neighbor identifier advertisement-interval command to globally change the 
default interval. 
The BGP advertisement-interval can also be separately set for each address family. If configured, this value over-rides 
the peer's default advertisement-interval for that address-family only. BGP will send route update-message for each 
AFI/SAFI based on the advertisement-interval configured for that AFI/SAFI. If no AFI/SAFI advertisement-interval is 
configured, the peer-based default advertisement-interval is used. 
In ICSR configurations, this feature can be used to speed route advertisements and improve network convergence times. 
The timers bgp icsr-aggr-advertisement-interval command is available in both the BGP Address-Family 
(VPNv4/VPNv6) Configuration and BGP Address-Family (VRF) Configuration modes.

Notes: 
 
seconds – sets the number of seconds as an integer from 0 to 30. Default: 0.
