protocol process first starts on the server router, the server sends router advertisement
packets every few seconds. Then, the server sends these packets less frequently.
The server responds to route solicitation packets it receives from a client. The response
is sent unicast, unless a router advertisement packet is due to be sent out
momentarily. IPv6 supports the following router advertisement mechanisms:
■
ICMPv6 Neighbor Discovery router advertisements
■
DHCPv6 Prefix Delegation
■
ICMPv6 Neighbor Discovery router advertisements followed by DHCPv6 Prefix
Delegation
The AAA service on the router stores the prefixes that it receives from the RADIUS
server during the PPPv6 authentication phase. After the PPPv6 link is established
between the subscriber and the B-RAS application running on the router, the router
receives the ICMPv6 router solicitation message, the DHCPv6 Solicit message, or
both of them based on the prefix advertisement mechanism. In previous releases,
you were not able to configure the RADIUS attribute or VSA to be used for IPv6
Neighbor Discovery router advertisements and DHCPv6 Prefix Delegation through
the CLI. As a result, the IPv6-NdRa-Prefix attribute returned in the Access-Accept
message was used for IPv6 Neighbor Discovery router advertisements and the
Framed-IPv6-Prefix RADIUS attribute in the Access-Accept message was used for
DHCPv6 Prefix Delegation.
In this release, you can control the RADIUS IETF attribute or VSA to be used for IPv6
Neighbor Discovery router advertisements and DHCPv6 Prefix Delegation by using
aaa ipv6-nd-ra-prefix framed-ipv6-prefix
and
aaa dhcpv6-delegated-prefix
delegated-ipv6-prefix
commands, respectively, in Global Configuration mode on
each virtual router.
aaa ipv6-nd-ra-prefix framed-ipv6-prefix
■
Use to set the Framed-IPv6-Prefix RADIUS attribute to be used for IPv6 Neighbor
Discovery router advertisements.
■
If you issue this command without issuing the
aaa dhcpv6-delegated-prefix
delegated-ipv6-prefix
command, a warning message is displayed prompting
you to configure the Delegated-IPv6-Prefix attribute for DHCPv6 Prefix Delegation.
The message also states that the Framed-IPv6-Prefix RADIUS attribute will be
used for both IPv6 Neighbor Discovery router advertisements and DHCPv6 Prefix
Delegation, if the Delegated-IPv6-Prefix attribute is not configured for Prefix
Delegation.
NOTE:
This warning message is displayed only if you configured the logging severity
level as warning for the aaaServerGeneral logging event category.
■
Use the
no
version to restore the default behavior, which causes the
IPv6-NdRa-Prefix VSA to be used for router advertisements.
■
Example
host1:VR1(config)#
aaa ipv6-nd-ra-prefix framed-ipv6-prefix
