! ============================================================================
! 02-bgp-ls.cfg  --  BGP-LS export of the IGP topology to the collector
! ============================================================================
! Feeds the OBMP-LinkState dashboards (ls_nodes, ls_links, ls_prefixes,
! LS Topology map). Enable on every router that runs IS-IS in the domain
! you want visualized; typically only the RRs need to actually SEND the
! link-state AF to the collector, but any router can distribute its local
! IGP database into BGP-LS.
!
! Three-part configuration:
!   Part A: tell IS-IS to distribute the LSDB into BGP-LS.
!   Part B: enable the link-state address-family in BGP globally.
!   Part C: activate the link-state AF toward the collector's RR peers.
!
! Apply after 01-bmp-basic.cfg.
! ============================================================================

! --- Part A: IS-IS distribute link-state ------------------------------------
router isis <ISIS_INSTANCE>
 distribute link-state
!

! --- Part B: BGP address-family link-state link-state (global) --------------
router bgp <LOCAL_ASN>
 address-family link-state link-state
 !
!

! --- Part C: activate LS AF per-neighbor (toward the RRs) -------------------
! On a client router, activate LS toward the two RRs. On an RR, activate
! toward its peer RR (and toward the collector's own BGP peer if present).
router bgp <LOCAL_ASN>
 neighbor <RR_LOOPBACK_1>
  address-family link-state link-state
  !
 !
 neighbor <RR_LOOPBACK_2>
  address-family link-state link-state
  !
 !

! --- Verify -----------------------------------------------------------------
!   show isis database detail
!   show bgp link-state link-state summary
!   show bgp link-state link-state
