BGP training course description
A detailed study of the Border Gateway Protocol, from the basics of how it works through to advanced issues
such as route reflectors, policy, filtering, route selection and routing registries. The course culminates
with a study of an industrial strength BGP template illustrating important issues such as graded dampening
and bogon filtering. Practical hands on with Cisco routers follow the major sessions to reinforce the theory.
Juniper configurations are also explored in the theory sessions.
Who will benefit?
Anyone who will be working with BGP.
BGP training course prerequisites
TCP/IP Foundation.
IP routing.
BGP training course objectives
By the end of the course delegates will be able to:
- Connect enterprises to the Internet, and ISP's to each other.
- Describe how BGP works.
- List, describe and configure the main BGP attributes.
- Configure policy control and filtering.
- Work with route aggregation and recognise the effects it has on BGP.
- Configure BGP features such as
- Peer groups
- Route reflectors
- Route dampening
Duration: 5 days

BGP training
course contents Basic BGP
IGP’s, EGP’s, What is BGP? BGP RIB, simple configuration
and troubleshooting.
The Internet and peering
AS's, AS numbers, Internet structure, ISP types, ISP network
design, IX’s, peering vs. transit, public/private
peering, bi/multi-lateral peering.
Peer relationships
IBGP differences from EBGP, next-hop-self, BGP relationship
with IGPs, redistribution, adding routes into BGP, synchronisation.
How BGP works
Incremental updates, Path vector protocols, BGP and the seven
layer model, the BGP header, message types, NLRI, withdrawn
routes, soft reconfiguration and route refresh, route dampening.
Route reflectors and confederations
Full mesh IBGP, Route reflectors, Route Reflector configuration
and design, confederations, migration issues.
BGPv4 aggregation
CIDR, benefits, techniques, shortcuts, configuring BGP aggregation,
leaking routes.
BGP Path selection
BGP attributes, attribute types, route selection order, Local
preference, AS prepend, MEDs.
Policies
What is policy? Examples, route filtering, AS filtering,
regular expressions, applying preference selectively, peer
groups.
Communities
What is a community, community names, communities for: peer
types and geography. RFC 1998, setting local preference
on other routers, default communities.
RIPE and routing registries
RIR’s, addressing services, allocations and assignments,
PI vs. PA addressing, obtaining IP and AS numbers. The RIPE
database, objects, RPSL, whois, looking glasses, specifying
policy in the routing registry, IRRToolSet.
BGP architectures
Stub vs. transit AS, when to use BGP, multihoming strategies
and issues, default routes, sub dividing a large AS. Multihop
EBGP, load balancing. Real world policies.
BGP security
