53-1003053-01

Basic configuration tasks

TurboIron(config-bgp-router)#exit

TurboIron(config)#int loopback 1

TurboIron(config-lbif-1)#ip address 10.0.0.1/24

Syntax: interface loopback <num>

The <num> value can be from 1 – 8 on Chassis Layer 3 Switches. The value can be from 1 – 4 on
the Compact Layer 3 Switch.

Adding BGP4 neighbors

The BGP4 protocol does not contain a peer discovery process. Therefore, for each of the router
BGP4 neighbors (peers), you must indicate the neighbor IP address and the AS each neighbor is in.
Neighbors that are in different ASs communicate using EBGP. Neighbors within the same AS
communicate using IBGP.

NOTE

If the Layer 3 Switch has multiple neighbors with similar attributes, you can simplify configuration by
configuring a peer group, then adding individual neighbors to it. The configuration steps are similar,
except you specify a peer group name instead of a neighbor IP address when configuring the
neighbor parameters, then add individual neighbors to the peer group. Refer to

“Adding a BGP4 peer

group”

on page 677.

NOTE

The Layer 3 Switch attempts to establish a BGP4 session with a neighbor as soon as you enter a
command specifying the neighbor IP address. If you want to completely configure the neighbor
parameters before the Layer 3 Switch establishes a session with the neighbor, you can
administratively shut down the neighbor. Refer to

“Administratively shutting down a session with a

BGP4 neighbor”

on page 680.

To add a BGP4 neighbor with IP address 10.157.22.26, enter the following command.

TurboIron(config-bgp-router)#neighbor 10.157.22.26

The neighbor <ip-addr> must be a valid IP address.

The neighbor command has some additional parameters, as shown in the following syntax:

Syntax: [no] neighbor <ip-addr> | <peer-group-name>
