BGP-4-Specific Accept Policy Parameters
This section shows you how to set BGP-4-specific accept policy parameters.
Parameter: Injection List
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.
MIB Object ID: 1.3.6.1.4.1.18.3.5.3.2.6.9.1.9
Note:
In the current release, 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. The Injection List parameter
replaces the received routes with the default route and places the default route
in the routing table.
Note:
The Injection List 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.
