How to Configure Traffic Engineering - Fast Reroute Link Protection
Enabling MPLS TE-FRR for EoMPLS on an Interface
To enable MPLS TE-FRR for EoMPLS on an interface, perform the steps given below:
SUMMARY STEPS
1. enable
2. configure terminal
3. pseudowire-class pw-class-name
4. no negotiation auto
5. service instance id ethernet
6. encapsulation dot1q vlan-id
7. rewrite ingress tag pop 1 symmetric
8. xconnect peer-ip-address vc-id pw-class pw-class-name
Step 8
preferred-path {[interface]
tunnel
tunnel-number
| peer
host-ip-address
}
[disable-fallback]
Example:
Router(config-pw-class)#
preferred-path interface Tunnel41
disable-fallback
Specifies the MPLS TE tunnel that traffic uses.
interface—Specifies the preferred path using an output
interface.
tunnel—Specifies an MPLS TE tunnel interface that is the
core-facing output interface.
tunnel-number—Tunnel interface number.
peer—Specifies a destination IP address or DNS name
configured on the peer provider edge (PE) router, which is
reachable through a label switched path (LSP).
host-ip-address—Peer host name or IP address.
peer—(Optional) Disables the router from using the default
path when the preferred path is unreachable.
Step 9
exit
Example:
Router(config-pw-class)# exit
Exits pseudowire class configuration mode and enters the global
configuration mode.
Step 10
mpls label protocol ldp
Example:
Router(config)# mpls label protocol
ldp
Specifies the label distribution protocol for an interface. Here LDP
protocol is used.
Step 11
mpls ldp igp sync holddown
milliseconds
Example:
Router(config)# mpls ldp igp sync
holddown 1000
Specifies how long an Interior Gateway Protocol (IGP) should wait
for Label Distribution Protocol (LDP) synchronization to be
achieved.
milliseconds—Peer host name or IP address.
