Abstract:
BGP is more and more used to transport routing information for
critical services. Some BGP updates may be critical to be received
as fast as possible : for example, in a layer 3 VPN scenario where a
dual-attached site is loosing primary connection, the BGP withdraw
message should be propagated as fast as possible to restore the
service. The same criticity exists for other address-families like
multicast VPNs where "join" messages should also be propagated very
fast.
Experience of service providers shows that BGP path propagation time
may vary depending on network conditions (especially load of BGP
speaker on the path) and too long propagation time are affecting
customer service.
It is important for service providers to keep track of BGP updates
propagation time to monitor quality of service for the customers. It
is also important to be able to identify BGP Speakers that are
slowing down the propagation.
This document presents a solution to transport timestamps of a BGP
path. The solution is targeted to be used using special identified
beacon prefixes that are single-homed.
