IPv6 routing information provided by the RADIUS server to users through the NAS. This attribute is in the following format of <IP address>[/<mask length>] [<next hop address> ] [<metric>], for example, 2001:db8:0:0:106::/64 2001:db8::106:a00:20ff:fe99:a998 1.

In user authorization scenarios, a next hop address is considered valid in the following scenarios:

1. If the next hop address contains all 0s or the next hop address is not specified, the user address is used as the next hop address.
2. For PPPoE or L2TP users, if RADIUS server delivers the Framed-Interface-Id attribute, the next hop address can be delivered as fe80::Framed-Interface-Id.
3. If the RADIUS server delivers the Framed-IPv6-Prefix attribute and the 64-bit prefix of the next hop address is the same as the delivered Framed-IPv6-Prefix attribute, the next hop address is considered valid.
4. If the RADIUS server delivers the Framed-IPv6-Address attribute and the delivered next hop address is the same as the delivered Framed-IPv6-Address attribute, the next hop address is considered valid.
5. If the RADIUS server delivers the Delegated-IPv6-Prefix attribute and the prefix of the delivered next hop address is the same as the delivered Delegated-IPv6-Prefix attribute, the next hop address is considered valid.

In AAA onload routes scenarios, the next hop address should be delivered and only the "null0" is supported.

Only one metric is supported. If multiple metrics are delivered, the value of the first metric is used. The metric ranges from 0 to 255. If the value exceeds 255, users fail to go online. A maximum of 128 Framed-route attributes can be delivered to each user. If more than 128 Framed-Route attributes are delivered, the device parses only the first 128 Framed-Route attributes delivered and user access is not affected.

The attribute can be carried only in accounting request packets for common users, and not carried in service accounting packets.

Accounting request packets can carry multiple framed routes. Considering RADIUS packet limit, a maximum of 128 framed routes can be carried. The attribute is encapsulated at the end of a packet to prevent impact on other attributes. If the maximum length is reached, excess characters are discarded.

Note: The attribute is only delivered to the PPPoE and IPoE. The attribute is discarded if the other access information receives it.
