Allowing Establishment Of Ebgp Connection To An Indirectly Connected Peer Or Peer Group; Controlling Route Generation; Configuration Prerequisites - HP 3600 v2 series Configuration Manual

To do...
Enter BGP view
Specify the source interface for
establishing TCP connections to a
peer or peer group
NOTE:
To establish multiple BGP connections between two routers, you must specify the source interface for
establishing TCP connections to each peer on the local router; otherwise, the local BGP router may fail to
establish TCP connections to a peer when using the outbound interface of the best route to the peer as the
source interface.
Allowing establishment of eBGP connection to an indirectly
connected peer or peer group
Direct physical links must be available between eBGP peers. If they are not, use the peer ebgp-max-hop
command to establish a TCP connection over multiple hops between two peers.
Follow these steps to allow establishment of eBGP connection to an indirectly connected peer or peer
group:
To do...
Enter system view
Enter BGP view
Allow the establishment of eBGP
connection to an indirectly
connected peer or peer group
NOTE:
Do not configure the peer ebgp-max-hop command if the two eBGP peers are directly connected.

Controlling route generation

Different from IGP, BGP focuses on route generation and advertisement control and optimal route
selection.
Generating BGP routes can be done in the following ways:
Configure BGP to advertise local networks
•
Configure BGP to redistribute routes from other routing protocols, including the default route
•

Configuration prerequisites

BGP connections must be created.
Use the command...
bgp as-number
peer { group-name | ip-address }
connect-interface interface-type
interface-number
Use the command...
system-view
bgp as-number
peer { group-name | ip-address }
ebgp-max-hop [ hop-count ]

Remarks
—
Required
By default, BGP uses the outbound
interface of the best route to the BGP
peer or peer group as the source
interface for establishing a TCP
connection to the peer or peer
group.

—
Optional
Not allowed by default.
