Common Configuration Tasks
82 Router Configuration Guide
Use the following CLI syntax to configure the router ID:
CLI Syntax: config>router
router-id router-id
interface ip-int-name
address {ip-address/mask | ip-address netmask}
[broadcast {all-ones | host-ones}]
The following example displays a router ID configuration:
A:ALA-4>config>router# info
#------------------------------------------
# IP Configuration
#------------------------------------------
interface "system"
address 10.10.0.4/32
exit
. . .
router-id 10.10.0.4
#------------------------------------------
A:ALA-4>config>router#
Configuring a Confederation
Configuring a confederation is optional. The AS and confederation topology design should
be carefully planned. Autonomous system (AS), confederation, and BGP connection and
peering parameters must be explicitly created on each participating router. Identify AS
numbers, confederation numbers, and members participating in the confederation.
Refer to the BGP section for CLI syntax and command descriptions.
Use the following CLI syntax to configure a confederation:
CLI Syntax: config>router
confederation confed-as-num members member-as-num
The following example displays the commands to configure the confederation topology
diagram displayed in Confederation Configuration.
NOTES:
• Confederations can be preconfigured prior to configuring BGP connections and
peering.
• Each confederation can have up to 15 members.
The following displays a confederation example.
