H3C S9500 Series Routing Switches
node Switch A of defect verification results, and switches data flows to the secondary
LSP.
In this case, only Switch A and Switch C need to support MPLS OAM, Switch B, Switch
D and Switch E do not.
1) Configuration preparation
At least two static LSPs are available between the ingress node and the egress
node to constitute a protection group. At the same time, a reverse static LSP from
the egress node to the ingress node is available for the egress node to notify
connectivity defects.
You need to configure a protection group, and specify the protection group ID,
protection switching delay, switch back mode and switch back wait time.
You need to enable MPLS OAM globally on the ingress node and the egress node.
You need to configure MPLS OAM parameters for the LSP to be verified and
enable the MPLS OAM function on the ingress node.
You need to configure MPLS OAM parameters for the LSP to be verified and
enable the MPLS OAM function on the egress node
2) Data preparation
To complete the configuration, you need to specify the following data:
IP addresses of VLAN interfaces of various switches and names of various static
LSPs, as shown in Figure 5-6.
Static LSPs borrow the loopback addresses of various switches. The destination
IP address of the primary and secondary LSPs is 3.3.3.3/32 and the destination IP
address of the reverse channel is 1.1.1.1/32.
In a protection group, the switch back delay is set to 10, that is, 1 second; the
switch back mode is revertive; the switch back wait time is 20, that is, 10 minutes.
The type of verification packet to be sent is set to CV and the transmission period
is the defaulted 1 second.
The reverse channel is set to share.
