BGP Link State with OSPF Segment Routing
This chapter contains configuration and validation of BGP-Link state extension for OSPF-SR.
Overview
Segment Routing (SR) allows a headend node to steer a packet flow along any path. Intermediate per-flow states are eliminated due to source routing. The headend node is said to steer a flow into a Segment Routing Policy (SR Policy). The header of a packet steered in an SR Policy is augmented with the ordered list of segments associated with that SR Policy. This feature is supported for the MPLS instantiations.
BGP-LS describes a mechanism by which Link-State (LS) and Traffic Engineering (TE) information from IGPs can be collected from networks and shared with external components using the BGP. This is achieved using a new BGP Network Layer Reachability Information (NLRI) encoding format. These components, while external to the network, require network state information on a real time basis. Specifically, they require link-state database information of each IGP node from the entire network. BGP protocol is used to collect the necessary information and to share with the external components and this is achieved using a NLRI encoding format.
A new NLRI is defined in order to advertise SR Policy to the headend of that policy. New sub-TLVs for the Tunnel Encapsulation Attribute are defined to carry SR related information.
Topology
Here we have taken 7 nodes out of which 6 nodes are OSPF-SR enabled routers and node 7 will act as controller. R3 belong to autonomous-system-100 and R5 belong to autonomous-system-200. R1's xe3 and R3's xe3 belong to Area-1. R2, R4 and R3 belong to Area-0 . R5 and R6 belong to Area-0 . We shall configure OSPF-SR on every node. We shall give distribute-BGP-LS on R3 and R5, after that we will make an E- BGP session between R3 and Controller and R5 and controller. Under link-state link-state address family we will activate the neighbors. Verification will be done on ASBRS which are R3 and R5.
All NLRIs (Node, Link and Prefix) should display proper SR information of nodes belong to other AS.
