Enabling eBGP Peering between different
Autonomous Systems
This example shows the minimum configuration required to enable eBGP on a VLAN
interface, when the routers belong to different Autonomous Systems. Router 1 and
Router 2 are two routers in different Autonomous Systems, 200 and 300, connecting to
network 2001:db8::/64.

awplus#
configure terminal
Enter the Global Configuration mode.
awplus(config)#
router bgp 200
Define the BGP4+ routing process. The number 200 specifies the
AS number of Router 1.
awplus(config-router)#
bgp router-id 10.10.10.11
Configure a fixed Router ID (10.10.10.11) for the BGP4+
routing process.
awplus(config-router#
neighbor 2001:db8::80:2
remote-as 300
Define BGP4+ neighbor Router 2, and establish a TCP session by
specifying the global unicast IPv6 address (2001:db8::80:2)
and the AS number (300) of neighbor Router 2.
awplus(config-router)#
address-family ipv6
Enter IPv6 Address Family Configuration mode for configuring
routing sessions that use IPv6 address prefixes.
awplus(config-router-af)#
neighbor 2001:db8::80:2
activate
Activate the exchange of information to the peer (neighbor)
Router 2 (2001:db8::80:2) and enable the exchange of IPv6
address prefix types with this neighbor. Note that other
information apart from prefixes is sent in updates. This command
activates the exchange of information for the peer defined.
awplus(config-router-af)#
exit-address-family
Exit IPv6 Address Family Configuration mode, and return to the
Router Configuration mode.
awplus(config-router)#
exit
Exit the Router Configuration mode, and return to the Global
Configuration mode.
