BGP-4-Specific Accept Policy Parameters

Parameter: Injection List

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

Policies

Default: An empty list

Options: A list of network identifiers

Function: Specifies network IDs to be included in the routing table in place of the

network IDs listed in the received advertisement.

Instructions: Specify a non-null value only if the Action parameter is set to Accept. The

values you enter in the injection list determine the action taken.

If you supply a list of network IDs, these IDs are injected into the routing

table instead of the actual received IDs.

If you use the default (an empty list), the actual received network IDs are

injected into the routing table. If you supply a list that includes the encoding

255.255.255.255/255.255.255.255, the actual received network IDs are

injected into the routing table along with the other IDs in the injection list.

This allows insertion of an aggregate or default along with the actual network.

The only valid network ID that you can include in an injection list is the

default ID, 0.0.0.0/0.0.0.0. This parameter replaces the received routes with

the default route and places the default route in the routing table. This

parameter associates the default route with the attributes of the best route that

matches the policy.

If you are constructing a BGP-3 or BGP-4 accept policy, keep in mind that the

Injection List parameter does not perform route aggregation as defined in

RFC 1654. To aggregate routes in a transit AS, you must construct an

announce policy and use the announce Advertise parameter.

MIB Object ID: 1.3.6.1.4.1.18.3.5.3.2.6.9.1.9
