Huawei AR1200 Series - Establishing the MP-EBGP Peer Relationship between Pes

The IPv4 routes with labels are matched.
4. Run:
apply mpls-label
The label is allocated to the IPv4 route.
5. Run:
quit
Return to the system view.
6. Run:
route-policy policy-name2 permit node node
The routing policy applied to the peer ASBR is created.
For the labeled IPv4 routes received from PE in the local AS, and sent to the remote
ASBR, this policy ensures that a new MPLS label is allocated.
7. Run:
apply mpls-label
The label is allocated to the IPv4 route.

3.8.4 Establishing the MP-EBGP Peer Relationship Between PEs
By importing extended community attributes to BGP, MP-EBGP can advertise VPNv4 routes
between PEs. PEs of different ASs are generally not directly connected. Therefore, to set up the
EBGP connection between the PEs of different ASs, configure the permitted maximum hops
between the PEs.
Procedure
l Configure a PE to advertise its loopback interface IP addresses used for peer relationship
establishment to the ASBRs of other ASs and peer PEs. You can also configure an ASBR
to send the loopback interface IP addresses of a PE used for peer relationship establishment
to the ASBRs of other ASs and peer PEs.
