# Configure ASBR 1. Establish MP-EBGP peer with ASBR 2 and perform no VPN target
filtering on the received VPNv4 routes, and then enable ASBR 1 to allocate labels based on the
next hop.
[ASBR1] bgp 100
[ASBR1-bgp] peer 192.1.1.2 as-number 200
[ASBR1-bgp] ipv4-family vpnv4
[ASBR1-bgp-af-vpnv4] peer 192.1.1.2 enable
[ASBR1-bgp-af-vpnv4] undo policy vpn-target
[ASBR1-bgp-af-vpnv4] apply-label per-nexthop
[ASBR1-bgp-af-vpnv4] quit
[ASBR1-bgp] quit
NOTE
The configurations of ASBR 2 are similar to that of ASBR 1 and are not mentioned here.
Step 5 Verify the configuration.
After the above configuration, the CEs can learn the interface routes of each other. CE1 and CE2
can be pinged successfully on each other.
Consider CE1 as an example.

Run the display bgp vpnv4 all routing-table command on the ASBR, and you can see the
VPNv4 routes on the ASBR.
Consider ASBR 1 for an example.
[ASBR1] display bgp vpnv4 all routing-table
