NOTE: Sample Configurations for enabling BGP routers are found at the end of this chapter.

1. Assign an AS number and enter ROUTER BGP mode.

CONFIGURATION mode

router /jointfilesconvert/79615/bgp as-number

• as-number: from 0 to 65535 (2 Byte) or from 1 to 4294967295 (4 Byte) or 0.1 to 65535.65535

(Dotted format).

Only one AS is supported per system.

NOTE: If you enter a 4-Byte AS number, 4-Byte AS support is enabled automatically.

a. Enable 4-Byte support for the BGP process.

NOTE: This command is OPTIONAL. Enable if you want to use 4-Byte AS numbers or if you

support AS4 number representation.

CONFIG-ROUTER-BGP mode

/jointfilesconvert/79615/bgp four-octet-as-support

NOTE: Use it only if you support 4-Byte AS numbers or if you support AS4 number

representation. If you are supporting 4-Byte ASNs, enable this command.

Disable 4-Byte support and return to the default 2-Byte format by using the no /jointfilesconvert/79615/bgp four-

octet-as-support command. You cannot disable 4-Byte support if you currently have a 4-

Byte ASN configured.

Disabling 4-Byte AS numbers also disables ASDOT and ASDOT+ number representation. All AS

numbers are displayed in ASPLAIN format.

b. Enable IPv4 multicast or IPv6 mode.

CONFIG-ROUTER-BGP mode

address-family [ipv4 | ipv6}

Use this command to enter BGP for IPv6 mode (CONF-ROUTER_BGPv6_AF).

2. Add a neighbor as a remote AS.

CONFIG-ROUTER-BGP mode

neighbor {ip-address | peer-group name} remote-as as-number

• peer-group name: 16 characters

• as-number: from 0 to 65535 (2 Byte) or from 1 to 4294967295 (4 Byte) or 0.1 to 65535.65535

(Dotted format)

Formats: IP Address A.B.C.D

You must Configure Peer Groups before assigning it a remote AS.

3. Enable the BGP neighbor.
