Step
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
the same AS and the ASBR in
another AS.
18. Enable exchange of labeled
IPv4 routes with the PE in the
same AS and the ASBR in
another AS.
19. Configure the ASBR-PE to set
itself as the next hop of routes
advertised to the PE in the
local AS.
20. (Optional.) Apply a routing
policy to routes incoming from
or outgoing to a peer or peer
group.
Configuring a routing policy on an ASBR-PE
A routing policy on an ASBR-PE does the following:
Assigns MPLS labels to routes received from the PEs in the local AS before advertising them to the
•
peer ASBR-PE.
• Assigns new MPLS labels to labeled IPv4 routes advertised to PEs in the local AS.
Which IPv4 routes are assigned with MPLS labels depends on the routing policy. Only routes that meet
the criteria are assigned with labels. All other routes are still common IPv4 routes.
To configure a routing policy for inter-AS option C on an ASBR-PE:
Step
1. Enter system view.
2. Create a routing policy and
enter routing policy view.
3. Match IPv4 routes carrying
labels.
4. Set labels for IPv4 routes.
