Ipv6 Bgp - Avaya 8800 Planning And Engineering

You can obtain AS numbers from the Inter-Network Information Center (NIC) or use private
AS numbers. If you use private AS numbers, be sure to design your Internet connectivity very
carefully. For example, you can introduce a central, well-known AS to provide interconnections
between all private ASs and/or the Internet. Before propagating the BGP updates, this central
AS strips the private AS numbers to prevent them from leaking to providers.
The following figure illustrates a design scenario in which you use multiple OSPF regions to
peer with the Internet.

IPv6 BGP+

The Avaya Ethernet Routing Switch 8800/8600 extends the BGPv4 process to support the
exchange of IPv6 routes using BGPv4 peering. BGP+ is an extension of BGPv4 for IPV6.
Note that the Ethernet Routing Switch 8800/8600 BGP+ support is not an implementation of
BGPv6. Native BGPv6 peering uses the IPv6 Transport layer (TCPv6 ) for establishing the
