You can use the BCC or Site Manager to supply values that BGP uses to set or
override fields in a BGP update that matches the policy.
Using Site Manager
Navigate to the policy-specific prompt and enter:
set
For example, the following command invokes a set prompt for BGP announce
policy pol_1:
announce/pol_1//jointfilesconvert/96470/bgp#
set
set//jointfilesconvert/96470/bgp/announce/pol_1#
To supply an override value, enter:
override_parameter value
override_parameter value
is one of the parameter/value pairs shown in Table 8-9.
Table 8-9. BCC Override Parameters for BGP Announce Policies
Parameter Values Function
as-path Null (default) or an
AS path
Specifies an AS path that overrides the AS-path
attribute of a route matching this policy. An AS path
is 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.
atomic aggregate Automatic (default)
Force
Ignore
Allows control over the atomic path attribute. By
default, the router automatically sets this attribute if it
knows that certain networks in aggregate range have
not been included in an aggregate advertisement
.
