Command Remarks
4. Use BFD to test the
connectivity of the LSP or
MPLS TE tunnel.
• Configure BFD to test the
connectivity of the LSP for the
specified FEC:
mpls bfd dest-addr mask-length
[ nexthop nexthop-address
[ discriminator local local-id
remote remote-id ] ] [ template
template-name ]
• Configure BFD to test the
connectivity of the MPLS TE tunnel
for the tunnel interface:
a. interface tunnel number
mode mpls-te
b. mpls bfd [ discriminator local
local-id remote remote-id ]
[ template template-name ]
c. quit
By default, BFD is not configured to
test the connectivity of the LSP or
MPLS TE tunnel.
This step is required for VPNv4 route
backup for a VPNv4 route and IPv4
route backup for a VPNv4 route.
For more information about the
commands in this step, see MPLS
Command Reference.
5. Create a routing policy and
enter routing policy view.
route-policy route-policy-name permit
node node-number
By default, no routing policy is
created.
This step is required when Method 2
is used to enable MPLS L3VPN FRR.
For more information about this
command, see Layer 3—IP Routing
Command Reference.
6. Set the backup next hop for
FRR.
apply fast-reroute backup-nexthop
ip-address
By default, no backup next hop
address is set for FRR.
This step is required when Method 2
is used to enable MPLS L3VPN FRR.
For more information about this
command, see Layer 3—IP Routing
Command Reference.
7. Return to system view.
quit N/A
8. Enter BGP view.
bgp as-number N/A
9. (Optional.) Use echo-mode
BFD to detect the
connectivity to the next hop
of the primary route.
primary-path-detect bfd echo
By default, ARP is used to detect the
connectivity to the next hop.
Use this command if necessary
when you configure VPNv4 route
backup for an IPv4 route.
For more information about this
command, see Layer 3—IP Routing
Command Reference.
10. Enter BGP-VPN instance
view.
ip vpn-instance vpn-instance-name N/A
