Basic BGP
IGPs, EGPs, What’s BGP? BGP RIB, in/out process, tables peers, adding routes.
Hands on: Simple configuration and troubleshooting.
The Internet and peering
ASs, AS numbers, Internet structure, ISP types, ISP network design, IXs, peering vs. transit, public/ private peering, bi/multi-lateral peering.
Hands on: AS information gathering.
How BGP works
Incremental updates, Path vector protocols, BGP protocol stack, the BGP header, message types, NLRI, withdrawn routes, route refresh, route dampening.
Hands on: More troubleshooting, packet analysis.
MBGP and IPv6
Multiprotocol routing, AFI, SAFI, MBGP and multicasts, IPv6, MPLS VPNs.
Hands on: IPv6
BGPv4 aggregation
CIDR, benefits, techniques, shortcuts, configuring BGP aggregation, leaking routes.
Hands on: Reducing routing table size.
BGP path selection
BGP attributes, attribute types, route selection order, Local preference, AS prepend, MEDs.
Hands on: Influencing traffic with BGP.
BGP routing policies
What is policy? Examples, route filtering, AS filtering, REs, applying preference selectively, peer groups.
Hands on: Sophisticated policies.
RIPE and routing registries
RIRs, Allocations, assignments, PI vs. PA. Objects, RPSL, routing registry,
Hands on: The RIPE database.
Automating BGP configuration
Automation tools, whois, IRRToolSet, Bogon lists, tracking bogon lists, HTTP, Peering, routing registries, DNS.
Communities
What is a community? Community names, communities for: peer types and geography. RFC 1998, default communities.
Hands on: Setting local preference on other routers.
Route servers
What are route servers? LINX route servers, route server policy control, What are route collectors, Looking glasses.
Hands on: Setting up and working with a route server.
Peer relationships
IBGP, EBGP, next hop self, advertising routes into/out of BGP, synchronisation.
Hands on: IBGP, troubleshooting a large BGP network.
Route reflectors and confederations
Full mesh IBGP, Route reflectors, RR configuration and design, confederations, migration issues.
Hands on: RR configuration.
BGP architectures
Stub vs. transit AS, when to use BGP, multihoming strategies and issues, default routes. Multihop EBGP, load balancing.
Hands on: Multihoming.
BGP security
RFC 7454, security steps, BGP TTL security, filters, RPKI, ROAs, rsync, rrdp, validators. A secure BGP template.
Hands on: RPKI prefix validation.
