Range: 0 to 120 seconds, 0 means disabled
Default: 60 seconds
• Recovery timer (for AApS only): Once the interface is up, the PE waits for the recovery timer value in order to allow
the CE running STP protocol to converge. This timer can be configured per segment-interface.
Range: 20 to 3600 seconds
Default: 20 seconds
Changing timers is only useful for scale configurations.
Note
Step 7 Use the commit or end command.
commit - Saves the configuration changes and remains within the configuration session.
end - Prompts user to take one of these actions:
• Yes - Saves configuration changes and exits the configuration session.
• No - Exits the configuration session without committing the configuration changes.
• Cancel - Remains in the configuration mode, without committing the configuration changes.
Configuring Multichassis Link Aggregation
Multichassis Link Aggregation (MCLAG) is used in scenarios involving Multi Homed Devices. You must
create an ICCP redundancy group in order to specify relevant MLACP parameters, such as, mlacp system
mac, mlacp system priority, mlacp node id and backbone interfaces.
Even though the redundancy group is created under the redundancy-iccp-group sub-mode, the solution does
not rely on an actual ICCP session between PEs connected to the same site. The mode singleton command
has been introduced to alert ICCP module.
Note
For more information on configuring MCLAG, refer to the Configuring Link Bundling on the Cisco ASR
9000 Series Router module in the Cisco ASR 9000 Series Aggregation Services Router Interface and Hardware
Component Configuration Guide.
Configuring BGP Routing Process
A prerequisite of PBB-EVPN involves enabling the new EVPN address family under the BGP routing process
and under BGP neighbor submode. For more information on BGP, refer to the Implementing BGP module in
the Cisco ASR 9000 Series Aggregation Services Router Routing Configuration Guide.
Perform this task to enable EVPN address family under BGP routing process and BGP neighbor submode.
