HPE FlexFabric 5950 Series Configuration Manual page 220

configure a routing policy to filter routes. Routes surviving the filtering are assigned labels, and all
others are advertised as common IPv4 routes.
To configure a routing policy, use the following commands:
•
if-match mpls-label—Matches routes carrying MPLS labels.
•
apply mpls-label—Sets MPLS labels for IPv4 routes advertised to a peer. You can use this
command together with if-match clauses. For example, the apply mpls-label command works
together with the if-match mpls-label command to set new MPLS labels for routes with MPLS
labels. The newly assigned labels are advertised along with the routes.
For more information about routing policy configuration, see Layer 3—IP Routing Configuration
Guide.
To configure an ASBR for inter-AS option C:
Step
1. Enter system view.
2. (Optional.) Create a routing
policy, and enter routing
policy view.
3. (Optional.) Match IPv4
routes carrying labels.
4. (Optional.) Set labels for
IPv4 routes.
5. Return to system view.
6. Enter interface view of the
interface connected to an
internal router of the AS.
7. Enable MPLS on the
interface.
8. Enable MPLS LDP on the
interface.
9. Return to system view.
10. Enter interface view of the
interface connected to the
remote ASBR.
11. Enable MPLS on the
interface.
12. Return to system view.
13. Enter BGP instance view.
14. Configure the PE in the same
AS as an IBGP peer.
15. Configure the ASBR in
another AS as an EBGP
peer.
16. Create the BGP IPv4 unicast
address family and enter its
view.
17. Enable exchange of IPv4
unicast routes with the PE in
