Set the route origin of the BGP routing
information
Cancel the route origin of the BGP
routing information
Set the tag domain of the OSPF routing
information
Cancel the tag domain of the OSPF
routing information
Note:
For the details about the apply mpls-label command, refer to MPLS L3VPN
Commands in the MPLS VPN Volume.
By default, perform no settings.
Note that if the routing information meets the match conditions specified in the
route-policy and also notifies the MED value configured with the apply cost-type
internal when notifying the IGP route to the EBGP peers, then this value will be
regarded as the MED value of the IGP route. The preference configured with the apply
cost-type internal command is lower than that configured with the apply cost
command, but higher than that configured with the default med command.
1.2.2 Configuring an IP Prefix List
An IP-prefix list is identified by an ip-prefix-name. Each IP-prefix-list can include
multiple entries with each specifying an IP prefix matching range. IP prefix entries are
identified by index-numbers. The order in which IP prefix entries are matched against
depends on the order of their index numbers.
Perform the following configuration in system view define/remove an IP prefix list:
To do...
Define prefix-list
Remove prefix-list
During the matching, the router checks list items identified by the index-number in the
ascending order. If only one list item meets the condition, it means that it has passed
the IP-prefix filtering (will not enter the testing of the next list item).
To do...
ip ip-prefix ip-prefix-name [ index index-number ] { permit |
deny } network len [ greater-equal greater-equal ] [ less-equal
less-equal ]
undo ip ip-prefix ip-prefix-name [ index index-number |
permit | deny ]
