Usage Information The no version of this command disables L3 routing.
Example
OS10(conf-vlt-1)# peer-routing
Supported Releases 10.2.0E or later
peer-routing-timeout
Congures the delay after which peer routing disables when the peer is not available. This command supports both IPv6 and IPv4.
Syntax
peer-routing-timeout value
Parameters value — Enter the timeout value in seconds, from 0 to 65535.
Default 0
Command Mode VLT-DOMAIN
Usage Information
When the timer expires, the software checks to see if the VLT peer is available. If the VLT peer is not available,
peer-routing disables on the peer. If you do not congure the timer, peer-routing does not disable even when the
peer is unavailable.
Example
OS10(conf-vlt-1)# peer-routing-timeout 120
Supported Releases 10.3.0E or later
primary-priority
Congures the priority when selecting the primary and secondary VLT peers during election.
Syntax
primary-priority value
Parameters value — Enter a lower value than the priority value of the remote peer. The range is from 1 to 65535. The default
value is 32768.
Default 32768.
Command Mode VLT-DOMAIN
Usage Information
• After you congure a VLT domain on each peer switch and connect the two VLT peers on each side of the VLT
interconnect, the system elects a primary and secondary VLT peer device. To congure the primary and
secondary roles before the election process, use the primary-priority command. Enter a lower value on
the primary peer and a higher value on the secondary peer. If the primary peer fails, the secondary peer (with
the higher priority) takes the primary role. If the primary peer (with the lower priority) later comes back online,
it is assigned the secondary role; there is no preemption.
• If the priority values congured on the two VLT peers are equal, VLT uses the default primary election
mechanism based on the values of the system MAC addresses of the two nodes. The VLT peer with the lowest
system MAC address assumes the primary role.
• If the heartbeat is up and the VLTi link goes down between the VLT peers, both the VLT peers retain their
primary and secondary roles. However, the VLT LAG on the secondary VLT peer shuts down.
NOTE: When you congure a priority for VLT peers using this command, the conguration is not
eective immediately. The primary priority conguration comes into eect the next time election is
triggered.
