that do not implement router preference. This feature is useful if there are other
RADVD-enabled devices on the LAN. The default is high.
STEP 7
Enter the MTU size. The MTU is the size of the largest packet that can be sent over
the network. The MTU is used in RAs to ensure all nodes on the network use the
same MTU value when the LAN MTU is not well-known. The default is 1500 bytes.
STEP 8
Enter the router lifetime value, or the time in seconds that the advertisement
messages will exist on the route. The default is 3600 seconds.
STEP 9
Click Save.
Configuring Router Advertisement Prefixes
To configure the RADVD available prefixes:
STEP 1
Choose Networking > IPv6 > Advertisement Prefixes.
STEP 2
Click Add.
STEP 3
Choose the IPv6 Prefix Type:
•
6to4—6to4 is a system that allows IPv6 packets to be transmitted over an
IPv4 network. It is used when an end user wants to connect to the IPv6
Internet using their existing IPv4 connection
•
Global/Local/ISATAP—By using ISATAP, you can integrate IPv6 traffic into a
IPv4 network environment. ISATAP uses a locally assigned IPv4 address to
create a 64-bit interface identifier for IPv6.
STEP 4
If you chose 6to4 in Step 3, enter the Site-level aggregation identifier (SLA ID.) The
SLA ID in the 6to4 address prefix is set to the interface ID of the interface on which
the advertisements are sent.
If you chose Global/Local/ISATAP in Step 3, enter the IPv6 prefix and prefix length.
The IPv6 prefix specifies the IPv6 network address. The prefix length variable is a
decimal value that indicates the number of contiguous, higher-order bits of the
address that make up the network portion of the address.
STEP 5
Enter the prefix lifetime, or the length of time over which the requesting router is
allowed to use the prefix.
STEP 6
Click Save.
