Segment Routing allows MPLS labels to be transported within deployed IGPs like OSPF and IS-IS, reducing MPLS complexity. It provides automated 50ms link and node protection for any topology or IGP metric. The goal is to allow applications to request permanent or time-specific SLAs, with the SDN controller expressing these in dynamic or explicit paths scaled by injecting paths in packets instead of network devices.
Bonjour,
I’m Bertrand Duvivier, NOSTG product manager and I’m going to give you an update on BGP flowspec
If we look at SP routing strategy, our goal is to provides solid networking foundation to enable all customers services.
As part of our ongoing innovation we are focusing on
Providing better usability and keeping IP networks simple.
Carrier Class services with 50 ms protection
Constantly improving on the scalability
Enabling IPv6 and MPLS IPv6
And more recently better tight Applications with the network.
You well see how Segment Routing will address all.
Let’s analyse a first use-case:
MPLS Segment Routing fundtion does transport all Labels requires to express dynamic path or explicit path within the IGP, ISIS or OSPF, and thus removing the need to run LDP and RSVP protocols, less protocols means less synchronization between them and simplification.
Use case 2
Segment routing does provide automated and optimized Topology Independent Fast ReRoute mechanism and thus allow for 50ms protection.
use-case 3:
The idea is for an Application to ask the SDN controller for a path to reach a destination with specific SLA. And the SDN controller to provide Dynamic or Explicit path expressed in a list of labels. As the dynamic or explicit path is in the packet and not in any network devices, the solution scale extremely high.
I ‘m happy to announce BGP flowspec support in XR 5.2.0 on ASR9K and CRS.
The Cisco BGP flowspec implementation is complete and will support
BGP flowspec based line as defined in RFC5575
IPv6 BGP flowspec
IP Next Hop redirection option
Does support IP and VPN address families
Forwarding plane has been optimize to support large scale flowspec deployment
Could be deployed as BGP flowspec, Controller, Route Reflection or client
