Configuring LDP
You can configure the propagation filter, as follows:
•
all
— All unsolicited label mappings are propagated to the VLAN. This is the
default setting.
•
none
— No unsolicited label mappings are propagated to the VLAN.
•
route-map <route_map>
— The specified route map is used to permit or deny the
propagation of unsolicited label mappings to the VLAN.
The only supported route map match operation keyword is
nlri-list
. If selected,
the access_profile parameter of the
nlri-list
keyword is compared to the FEC that
is associated with each label mapping.
For more information on route maps, see the ExtremeWare Software Users
Guide.
Configuring an LDP Label Advertisement Filter
To configure an LDP label advertisement filter, use the following command:
config mpls ldp advertise [direct | rip | static] [all | none | route-map
<route_map>]
This command configures a filter to be used by LDP when originating unsolicited label
mapping advertisements to LDP neighbors.
You can configure how the advertisement filter is applied, as follows:
•
direct
— The advertisement filter is applied to the FECs associated with direct
routes exported by OSPF.
•
rip
— The advertisement filter is applied to the FECs associated with RIP routes
exported by OSPF.
•
static
— The advertisement filter is applied to the FECs associated with static
routes exported by OSPF.
You can configure the advertisement filter, as follows:
•
all
— All unsolicited label mappings are originated for all routes of the specified
type (direct, RIP, or static). This is the default setting for direct routes.
•
none
— No unsolicited label mappings are originated for all routes of the specified
type. This is the default setting for RIP and static routes.
