Feature
Next hop delayed
response allows a BGP
peer to delay
responding to the next
hop unreachable event
and to respond to this
event only after the
switched route is
available. Therefore,
the volume of traffic
lost during a route
switchover is
minimized.

Feature
BFD for BGP is used to
detect faults on the link
between BGP peers
and notify the fault to
BGP, speeding up BGP
route convergence.
8 BGP Configuration
Note
The BGP next hop
delayed response is
applicable only to the
scenario where
multiple links are
available between the
next hop and the
destination. If there is
only one link between
the next hop and the
destination,
configuring the BGP
next hop delayed
response may increase
the volume of traffic
lost during a link
failure because link
switching is not
possible in this case.
