XGS3 Command Guide
39-5
Default: Hello message includes Genid option
Command Mode: Interface Configuration Mode
Usage Guide: The command is used to interactive with old Cisco IOS Version.The command can
configure on IPv6 tunnel interface, but it is successful configuration to only configure tunnel carefully.
Example: Configure hello messages transmitted by switch to exclude Genid option.
Switch(Config-if-Vlan1)#ipv6 pim exclude-genid
39.2.8 ipv6 pim hello-holdtime
Command: ipv6 pim hello-holdtime <value>
no ipv6 pim hello-holdtime
Function: Configure and cancel Holdtime item value in Hello message, the value describes neighbor
overtime. If it goes over the time and does not receive hello message of the neighbor, the register of the
neighbor will be delete.
Parameter: <value> is configure time of holdtime.
Default: Define 3.5 times of Hello_interval, and default hello_interval as 30s, so default value of
hello_holdtime is 105s.
Command Mode: Interface Configuration Mode
Usage Guide: If no setting, hello time will default current 3.5 times of Hello_interval. If setting hello time
is less than current hello_interval, this setting will be declined. When updating hello_interval every time,
hello_holdtime will be also update based on these rules below: if hello_holdtime does not be configured,
or if hello_holdtime configured is less than current hello_interval, hello_holdtime will be modified to 3.5
times Hello_interval, otherwise, keeps configured value. The command can configure on IPv6 tunnel
interface, but it is successful configuration to only configure tunnel carefully.
Example: Configure hello holdtime setting on interface vlan1 to 10.
Switch (config)# interface vlan1
Switch (Config -if-Vlan1)#ipv6 pim hello-holdtime 10
39.2.9 ipv6 pim hello-interval
Command: ipv6 pim hello-interval < interval>
no ipv6 pim hello-interval
Function: Configure interface PIM-DM hello message interval; the “no ipv6 pim hello-interval”
command restores default value.
Parameter: < interval> is interval of periodically transmitted PIM-DM hello message, value range from
1s to 18724s.
Default: Default interval of periodically transmitted PIM-DM hello message as 30s.
Command Mode: Interface Configuration Mode
Usage Guide: Hello message makes PIM-DM switch mutual location, and ensures neighbor ship.
PIM-DM switch announces existence itself by periodically transmitting hello messages to neighbors. If it
doesn’t receive hello messages from neighbors in regulation time, it confirms that the neighbors were lost.
Configuration time is not more than neighbor overtime. The command can configure on IPv6 tunnel
