Configuring Router Advertisement Parameters
To configure the Router Advertisement parameters, use the following sample configuration:
config
profile icmpv6 icmpv6profile_name
options { hop-limit hop_limit | mtu mtu_size | reachable-time reachable_time | retrans-timer retrans_timer | router-lifetime router_lifetime | virtual-mac virtual_mac }
ra trigger handover { false | true }
end
NOTES:
-
profile icmpv6 icmpv6profile_name : Specify the ICMPv6 profile name. icmpv6profile_name must be an alphanumeric string.
-
options { hop-limit hop_limit | mtu mtu_size | reachable-time reachable_time | retrans-timer retrans_timer | router-lifetime router_lifetime | virtual-mac virtual_mac } : Configure the ICMPv6 options.
-
hop-limit hop_limit : Configure the hop limit. hop_limit must be an integer in the range of 0–255. Default: 255.
-
mtu mtu_size : Configure the MTU size. Default: 1500.
mtu_size must be an integer in the range of 1280-1500.
-
reachable-time reachable_time : Configure the reachable time in milliseconds. Default: 0.
reachable_time must be an integer in the range of 0-3600.
-
retrans-timer retrans_timer : Configure the retransmission timer in milliseconds. Default: 0.
retrans_timer must be an integer in the range of 0-4294968.
-
router-lifetime router_lifetime : Configure the router lifetime in seconds. router_lifetime must be an integer in the range of 0–65535. Default: 65535.
-
virtual-mac virtual_mac : Configure the local virtual MAC address.
-
-
ra trigger handover { false | true } : Configure the trigger to send router advertisements for Wi-Fi handovers.
Verifying the Configuration
Use the show running-config profile icmpv6 command to verify the Router Advertisement configuration.
The following configuration is an example output of the command:
[unknown] smf(config)# show running-config profile icmpv6
profile icmpv6 icmpprf1
options hop-limit 255
options mtu 1500
options reachable-time 0
options retrans-timer 0
options router-lifetime 65535
options virtual-mac b6:6d:57:45:45:45
ra trigger handover true
exit
