fast-reroute tie-break
Use this command to set the tie-breaking policy for selecting a fast reroute repair path. You assign a priority to each type of repair path.
Use the no parameter with this command to set the tie-breaking policy for a specific type of repair path to its default priority. To set all types of repair paths to their default priorities, do not specify a repair path with the no form of this command.
Command Syntax
fast-reroute tie-break (primary-path|interface-disjoint|node-protecting|broadcast-interface-disjoint) index <1-4>
no fast-reroute tie-break (primary-path|interface-disjoint|node-protecting|broadcast-interface-disjoint) index <1-4>
no fast-reroute tie-break
Parameters
primary-path
When there are multiple loop-free alternate paths. The primary path is selected for an frr if it is node-protecting as well as link-protecting
interface-disjoint
Do not select point-to-point interfaces that have no alternate next hop for rerouting if the primary gateway fails, thus protecting the interface.
node-protecting
Bypass the primary-path gateway router which might not protect the router that is the next hop in the primary path.
broadcast-interface-disjoint
Do not use the interface if connected to a broadcast network. Repair paths protect links when a repair path and a protected primary path use different next-hop interfaces. However, on broadcast interfaces, if the repair path is computed via the same interface as the primary path, but their next-hop gateways are different, the router is protected but the link might not be.
index
Tie break priority. A lower value has higher preference.
<1-4>
Range of priority values.
Defaults
The default priority scheme is:
1. primary-path
2. interface-disjoint
3. node-protecting
4. broadcast-interface-disjoint
Command Mode
Router mode
Applicability
This command was introduced before OcNOS version 1.3.
Examples
#configure terminal
(config)#router ipv6 ospf 200
