Peer of vpn instance :
vpn instance vpn1 :
10.1.1.1 4 65410 46 46 0 00:37:41 Established 5
Step 7 Set up an MP-IBGP adjacency between the PEs.
# Configure PE1.
[PE1] bgp 100
[PE1-bgp] peer 2.2.2.2 as-number 100
[PE1-bgp] peer 2.2.2.2 connect-interface loopback 1
[PE1-bgp] peer 3.3.3.3 as-number 100
[PE1-bgp] peer 3.3.3.3 connect-interface loopback 1
[PE1-bgp] ipv4-family vpnv4
[PE1-bgp-af-vpnv4] peer 2.2.2.2 enable
[PE1-bgp-af-vpnv4] peer 3.3.3.3 enable
[PE1-bgp-af-vpnv4] quit
# Configure PE2.
[PE2] bgp 100
[PE2-bgp] peer 1.1.1.1 as-number 100
[PE2-bgp] peer 1.1.1.1 connect-interface loopback 1
[PE2-bgp] ipv4-family vpnv4
[PE2-bgp-af-vpnv4] peer 1.1.1.1 enable
[PE2-bgp-af-vpnv4] quit
# Configure PE3.
[PE3] bgp 100
[PE3-bgp] peer 1.1.1.1 as-number 100
[PE3-bgp] peer 1.1.1.1 connect-interface loopback 1
[PE3-bgp] ipv4-family vpnv4
[PE3-bgp-af-vpnv4] peer 1.1.1.1 enable
[PE3-bgp-af-vpnv4] quit
Run the display bgp vpnv4 all peer command on the PEs, and you can see that MP-IBGP
adjacencies are established between PEs.
Take PE1 for example.
[PE1] display bgp vpnv4 all peer
BGP local router ID : 1.1.1.1
Local AS number : 100
Total number of peers : 2 Peers in established state : 2

3.3.3.3 4 100 24 19 0 00:17:18 Established 5
Step 8 Configure routing policy for VPN FRR.
[PE1] ip ip-prefix vpn_frr_list permit 2.2.2.2 32
[PE1] route-policy vpn_frr_rp permit node 10
[PE1-route-policy] if-match ip next-hop ip-prefix vpn_frr_list
[PE1-route-policy] apply backup-nexthop 3.3.3.3
[PE1-route-policy] quit
Step 9 Enable VPN FRR.
[PE1] ip vpn-instance vpn1
[PE1-vpn-instance-vpn1] vpn frr route-policy vpn_frr_rp
[PE1-vpn-instance-vpn1] quit
# View the backup next hop, backup label, and backup tunnel ID.
<PE1> display ip routing-table vpn-instance vpn1 10.3.1.0 verbose
Routing Table : vpn1
