How to Configure Remote Loop-Free Alternate - Fast Reroute
Configuring LFA-FRR for ATM/IMA
To configure LFA-FRR for ATM/IMA, complete the following steps:
Note Effective with Cisco IOS release 15.4(1)S, the TDM Pseudowire Redundancy over FRR feature is
supported.
SUMMARY STEPS
1. enable
2. configure terminal
3. controller {e1 | t1} slot/port
4. ima-group ima-group-number
5. exit
6. interface ATM slot/IMA group-number
7. no ip address
8. no atm enable-ilmi-trap
9. pvc VPI/VCI l2transport
10. xconnect ip-address encapsulation mpls
11. backup peer peer-ip-address vc-id
Step 9
xconnect
peer-ip-address vc-id
encapsulation mpls
Example:
Router(config-if-srv)# xconnect
10.0.0.4 4 encapsulation mpls
Binds an attachment circuit to a pseudowire, and to configure an
Any Transport over MPLS (AToM) static pseudowire.
• peer-ip-address—IP address of the remote provider edge (PE)
peer. The remote router ID can be any IP address, as long as it
is reachable.
• vc-id—The 32-bit identifier of the virtual circuit (VC) between
the PE routers.
• encapsulation—Specifies the tunneling method to encapsulate
the data in the pseudowire.
• mpls—Specifies Multiprotocol Label Switching (MPLS) as the
tunneling method.
Step 10
backup peer
peer-ip-address vc-id
Example:
Router(config-if-ether-vc-xconn)#
backup peer 10.0.0.5 4
Specifies a redundant peer for a pseudowire VC.
• peer-ip-address—IP address of the remote peer.
