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

[Steve Glendinning]

Hi all,

I'm trying to configure multilink PPP on a Cisco 7200 (NPE-G2) LNS
(12.4(4)XD11), but the LNS is refusing to create the bundle:

Aug  7 15:44:19 BST: Vi714 MLP: Request add link to bundle
Aug  7 15:44:19 BST: Vi714 MLP: Adding link to bundle
Aug  7 15:44:19 BST: Vi714 MLP: Missing AAA per-user attributes
Aug  7 15:44:19 BST: Vi714 MLP: Bundle failed in creation/cloning
Aug  7 15:44:19 BST: Vi714 MLP: Link not added to bundle
Aug  7 15:44:19 BST: Vi714 IPCP: LCP not open, discarding packet
Aug  7 15:44:21 BST: Vi714 IPCP: LCP not open, discarding packet
Aug  7 15:44:23 BST: Vi714 IPCP: LCP not open, discarding packet
Aug  7 15:44:25 BST: Vi714 IPCP: LCP not open, discarding packet

Any idea how I can find out which AAA per-user attribute(s) it's
missing and complaining about?

The RADIUS server is returning these attributes for the account:

Aug  7 15:16:58 BST: RADIUS:  Service-Type        [6]   6   Framed
               [2]
Aug  7 15:16:58 BST: RADIUS:  Framed-Protocol     [7]   6   PPP
               [1]
Aug  7 15:16:58 BST: RADIUS:  Framed-IP-Netmask   [9]   6   255.255.255.255
Aug  7 15:16:58 BST: RADIUS:  Framed-IP-Address   [8]   6   xx.xx.xx.xx
Aug  7 15:16:58 BST: RADIUS:  Vendor, Cisco       [26]  46
Aug  7 15:16:58 BST: RADIUS:   Cisco AVpair       [1]   40
"ip:dns-servers=xx.xx.xx.xx yy.yy.yy.yy"
Aug  7 15:16:58 BST: RADIUS:  Vendor, Cisco       [26]  45
Aug  7 15:16:58 BST: RADIUS:   Cisco AVpair       [1]   39
"ipv6:prefix#1=XXXX:XXXX:XXXX:XXXX::/64"
Aug  7 15:16:58 BST: RADIUS:  Vendor, Cisco       [26]  39
Aug  7 15:16:58 BST: RADIUS:   Cisco AVpair       [1]   33
"ipv6:route#1=XXXX:XXXX:XXXX::/48"
Aug  7 15:16:58 BST: RADIUS:  Acct-Interim-Interva[85]  6   3600

And I've tried also adding these with no joy:

Cisco-Avpair = "multilink:max-links=2"
Cisco-Avpair = "multilink:min-links=1"
Cisco-Avpair = "multilink:load-threshold=10"
Cisco-Avpair = "preauth:ppp-multilink=1"

Thanks,
