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

Policies

Default: Empty string

Options: Any regular expression or empty string

Function: Allows AS_PATH pattern matching.

Instructions: Enter a valid regular expression to indicate an AS and its position in a path.

The policy applies to all routes whose AS path includes the AS in that position.

For example, the expression * 200 $ means that the policy applies to all routes

whose AS_PATH attribute contains AS 200 as the last AS in the path.

MIB Object ID: 1.3.6.1.4.1.18.3.5.3.2.6.10.1.32

Parameter: BGP Community to announce

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

Policies

Default: An empty list

Options: A list of BGP communities

Function: Specifies a list of one or more BGP communitiesto associate with this policy.

Instructions: Set the BGP Community attribute action parameter to Append or Replace and

supply a list of communities as an octet string using the following format: each

community ID is 4 bytes long; 0 in the two most significant bits causes the

router to perform the match on the lower 16 bits; the default empty list means

“announce any list.”
