Configurable BGP Route Advertisement Interval for ICSR
from deploying BGP Prefix Independent Convergence (PIC) in the Optical Transport Network Generation
Next (OTNGN).
BGP PIC is intended to improve network convergence which will safely allow for setting aggressive ICSR
failure detection timers.

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.
