Bgp Configuration Views - HP 6125XLG Configuration Manual

MP-BGP uses these two attributes to advertise feasible and unfeasible routes for different network layer
protocols. BGP speakers not supporting MP-BGP ignore updates containing these attributes and do not
forward them to its peers.
The current MP-BGP implementation supports multiple protocol extensions, including VPN, IPv6, and
multicast. For more information about VPN, see MCE Configuration Guide.
Address family
MP-BGP uses address families and subsequent address families to identify different network layer
protocols for routes contained in the MP_REACH_NLRI and MP_UNREACH_NLRI attributes. For example,
an Address Family Identifier (AFI) of 2 and a Subsequent Address Family Identifier (SAFI) of 1 identify
IPv6 unicast routing information carried in the MP_REACH_NLRI attribute. For address family values, see
RFC 1700.

BGP configuration views

BGP uses different views to manage routing information for different address families and different VPN
instances. Most BGP commands are available in all BGP views. BGP supports multiple VPN instances by
establishing a separate routing table for each VPN.
Table 7 describes different BGP views.

Remarks
Configurations in this view are
effective for routes of all address
families on the public network and in
all VPN instances (such as
confederation, GR, and logging
configurations), or only for routes of
all address families on the public
network.
Configurations in this view are
effective for IPv4 unicast routes on the
public network.
Configurations in this view are
effective for IPv6 unicast routes on the
public network.
Configurations in this view are
effective for routes of all address
families in the specified VPN
instance.
