Configuring IP Exterior Gateway Protocols (BGP and EGP)

B-50

308628-14.00 Rev 00

Parameter: Replace As Path

Path: Configuration Manager > Protocols > IP > Policy Filters > BGP-4 > Announce

Policies

Default: Null

Options: An AS path

Function: Specifies an AS path that overrides the AS-path attribute of a route matching

this policy.

Instructions: Constructs a BGP-4 AS path composed of AS path segments. Each AS path

segment includes a path segment type, a path segment length specifying the

number of ASs in the segment, and a path segment value containing one or more

AS numbers. There are two AS path segment types: type 1, an unordered set of

ASs that a route in the UPDATE message has traversed, and type 2, an ordered

set of ASs that a route in the UPDATE message has traversed.

MIB Object ID: 1.3.6.1.4.1.18.3.5.3.2.6.10.1.27

Parameter: Local Preference Override

Path: Configuration Manager > Protocols > IP > Policy Filters > BGP-4 > Announce

Policies

Default: False

Options: False

True

Function: Indicates whether or not you are supplying an override value for the Local

Preference path attribute in the routing Update message. (The Local Pref

attribute is valid only in an Update advertised to an IBGP peer.) If you select

False, the router uses the IP route weight value to calculate the LOCAL_PREF

path attribute.

Instructions: To override the Local Preference attribute, select True and supply a value for

the Local Preference Value parameter.
