The ISG is running IOS-XE Version 16.6.4.
We have a select number of radius-server attributes configured. However, the ISG is sending the radius attribute 151 in its Accounting-Request packet. In the packet and under the RADIUS Protocol > Attribute Value Pairs, their list AVP: t=PMIP6-Home-HN-Prefix(151) l=10 val=[invalid reserved byte for IPv6 prefix]. Below you can see a Radius Accounting-Request Packet with some attributes removed.
RADIUS Protocol
Code: Accounting-Request (4)
Packet identifier: 0xcd (205)
Length: 430
Authenticator: xxxxxxxxxxxxxxxxxxxxxxxx
[The response to this request is in frame 153]
Attribute Value Pairs
... other attributes removed ...
AVP: t=PMIP6-Home-HN-Prefix(151) l=10 val=[invalid reserved byte for IPv6 prefix]
Type: 151
Length: 10
Attribute 151 is the attribute I would like to remove or exclude from sending.
The IOS does not list the radius attribute 151 so that we can exclude, below are the ios command output
isg(config)#radius-server attribute ?
11 Filter-Id attribute configuration
188 Num-In-Multilink attribute configuration

Does anyone have any idea about how to exclude radius attribute 151?
Thanks
