NOTE
An MRP ring is considered to be a single hop, regardless of the number of nodes in the ring.
To change the TTL for a VRID, enter a command such as the following at the configuration level for the
VRID.
device(config-vlan-200-vrid-1)#initial-ttl 5
Syntax: [no] initial-ttl num
The num parameter specifies the TTL and can be from 1 - 255. The default TTL is 2.
Changing the hello interval setting
The Master periodically sends Hello messages to the Backups. To change the Hello interval, enter a
command such as the following at the configuration level for the VRID.
device(config-vlan-200-vrid-1)#hello-interval 10
Syntax: [no] hello-interval num
The num parameter specifies the interval and can be from 1 - 84 seconds. The default is 1 second.
NOTE
The default Dead interval is three times the Hello interval plus one-half second. Generally, if you change
the Hello interval, you also should change the Dead interval on the Backups.
NOTE
If you change the timer scale, the change affects the actual number of seconds.
Changing the dead interval setting
The Dead interval is the number of seconds a Backup waits for a Hello message from the Master before
determining that the Master is dead. The default is 3 seconds. This is three times the default Hello
interval.
To change the Dead interval, enter a command such as the following at the configuration level for the
VRID.
device(config-vlan-200-vrid-1)#dead-interval 30
Syntax: [no] dead-interval num
The num parameter specifies the interval and can be from 1 - 84 seconds. The default is 3 seconds.
NOTE
If you change the timer scale, the change affects the actual number of seconds.
