[c-nsp] Cisco 7200 LNS Multilink per-user RADIUS attributes

[Steve Glendinning]

Hi all,

I'm resurrecting this old thread to record my progress for the archives.
 Hopefully this will spare someone else a day of head scratching.

It turns out that the following RADIUS attribute prevents multilink from
establishing a bundle:

        Cisco-AVPair += "ipv6:prefix#1=2A02:AAAA:BBBB:CCCC::/64",

When this attribute is present I see the mysterious error "MLP: Missing AAA
per-user attributes".  Removing this IPv6 attribute from the account,
multilink works fine.

This is a problem on these IOS versions:

12.4(4)XD11
12.4(4)T4
12.4(24)T5

And it seems to work on these IOS versions:

12.2(33)SRE3
15.0(1)M7
15.1(4)M2

Now for my next challenge I have to pick the right train to upgrade to with
no new bugs...
