Disabling affinity
Disable the use of sending out session attribute objects with resource affinity data.
With affinity enabled, the LSP can match desired attributes, represented by affinity bits, to link attributes. This allows the LSP to include (include-any) or exclude (exclude-any) the configured administrative groups in the LSP.
Procedure steps
Step Action
1 To enter the configuration mode, enter:
configure terminal 2 To select the LSP, enter:
mpls traffic-eng-lsp <LSP-name>
3 To configure affinity, enter:
{primary | secondary} {no-affinity | affinity}
--End--Table 67
Variable definitions
Variable Value
primary Specifies the primary LSP.
secondary Specifies the secondary LSP.
no-affinity Disables affinity.
affinity Enables affinity.

Configuring fast reroute bandwidth Configure bandwidth for fast reroute.
Procedure steps
Step Action
1 To enter the configuration mode, enter:
configure terminal
Configuring Fast Reroute for constrained path LSP 105
2 To select the LSP, enter:
mpls traffic-eng-lsp <LSP-name>

[no] primary fast-reroute bandwidth <bandwidth>
--End--Table 70
Variable definitions
Variable Value
[no] Deletes the fast reroute bandwidth configuration.
<bandwidth> Specifies the fast reroute bandwidth, from 1 to 10000000000 bits. You can also specify the bandwidth in units of kilobits, megabits, or gigabits (k, m, or g). For example, to specify 10 kilobits, enter 10k.
Specifying the administrative groups to include in the fast reroute Specify the administrative groups to include in the fast reroute set up. To be added to the alternate route, links must belong to at least one of the administrative groups listed in the include-any list.
Procedure steps
Step Action
1 To enter the configuration mode, enter:
configure terminal 2 To select the LSP, enter:
mpls traffic-eng-lsp <LSP-name>
3 To configure the administrative groups to include, enter:
[no] primary fast-reroute include-any <groupname>
--End--Table 71
Variable definitions
Variable Value
[no] Deletes the specified group from the include-any list.
<groupname> Specifies the administrative groups to include in the
106 RSVP-TE LSP configuration
Excluding administrative groups from the fast-reroute
Specify the administrative groups to be excluded from the fast reroute set up.
When you specify the exclude-any list, any link that belongs to even one of the groups specified in the exclude list cannot be chosen for the alternate route.
Procedure steps
Step Action
1 To enter the configuration mode, enter:
configure terminal 2 To select the LSP, enter:
mpls traffic-eng-lsp <LSP-name>
3 To configure the administrative groups to exclude, enter:
[no] primary fast-reroute exclude-any <groupname>
--End--Table 72
Variable definitions
Variable Value
[no] Deletes the specified group from the exclude-any list.
<groupname> Specify the administrative group to be excluded from the fast reroute set up.
Configuring fast reroute setup priority
Configure the setup priority to determine whether the alternate path can preempt an existing LSP. The setup priority of the alternate path must be higher than the hold priority of an existing LSP for the existing LSP to be preempted.
Procedure steps
Step Action
1 To enter the configuration mode, enter:
configure terminal 2 To select the LSP, enter:
mpls traffic-eng-lsp <LSP-name>
Configuring Fast Reroute for constrained path LSP 107
3 To configure fast reroute setup priority, enter:
[no] primary fast-reroute setup-priority <0-7>
--End--Table 73
Variable definitions
Variable Value
[no] Sets the setup priority to the default value:
7 (lowest).
<0-7> Specifies the fast-reroute setup priority, from highest priority (0) to lowest priority (7)
Configuring fast reroute hold priority Set the hold priority for the detour LSP
Configure the hold priority value for the alternate path. The hold
priority determines the degree to which the alternate path holds onto its reservation for a session after the path has been set up successfully.
When the hold priority is high, the existing path is less likely to give up its reservation.
Procedure steps
Step Action
1 To enter the configuration mode, enter:
configure terminal 2 To select the LSP, enter:
mpls traffic-eng-lsp <LSP-name>
3 To configure the hold priority, enter:
[no] primary fast-reroute hold-priority <0-7>

Variable Value
[no] Sets the hold priority to the default value:
0 (highest).
<0-7> Specifies the fast reroute hold priority, from highest
108 RSVP-TE LSP configuration
