VPDN IOS12.2.11T multiple the login domain not work

Ask to expert , Today I using IOS Version 12.2(6) at LNS RSP2 (Router7507) but its have problem to client if use PPP thru LAC . LNS will not forward packet if client as PPP but It not problem if use MPP (Multiple link ). coz come from enable the IP CEF Its can't not work with VPDN. if I'm disable IP CEF the CPU utilization too high. I'm found IOS 12.2.11T resolved about these problem . since I have upgrade IOS to 12.2.11T I got a problem are Its can't use mutiple login domain . I've three diffrent login domain and point to diffrent radius server I use configure following :

=====

aaa new-model

aaa authentication login default local group radius

aaa authentication login vty line

aaa authentication ppp default local group radius

aaa authorization network default if-authenticated group radius local

aaa accounting network default start-stop group radius

ip host domain1.com 192.168.0.1

ip host domain2.com 192.168.0.2

ip host domain3.com 192.168.0.3

radius-server host 192.168.0.1 auth-port 1645 acct-port 1646

radius-server host 192.168.0.2 auth-port 1645 acct-port 1646

radius-server host 192.168.0.3 auth-port 1645 acct-port 1646

radius-server retransmit 3

radius-server directed-request

radius-server key [hind]

radius-server authorization permit missing Service-Type

=====

But can use just one domain are domain1.com to redius 192.168.0.1 for other login domain not work . debug radius message tell :

1d12h: RADIUS: directed-request server 192.168.0.2 is not in list

1d12h: RADIUS: directed-request server 192.168.0.3 is not in list

====

and debug tell directed-request to first radius in list I have no real log to show you . I have just one this problem . Right now I must goback use IOS 12.2(6) becoz it no have problem abt multiple login domain . kindly suggestion

Thanks

Re: VPDN IOS12.2.11T multiple the login domain not work

To the best of my knowledge, Cisco IOS Version 12.2(6) is still in the LD state. It is not exactly a good practice to use LD versions on your production router. It's always safer from the reliability and security point view to install a GD version.

The other IOS version that you are using, ie 12.2.11T, is in the ED (Early Deployment) state and I am not sure about the stability of this version either.

I guess either way you will have to wait a little longer for the versions to become stable or choose some other IOS from the SA.

You can use the software advisor(SA) to help you choose a suitable version. The software advisor is available at http://www.cisco.com/cgi-bin/Support/CompNav/CN1.pl?Q2Submit=ProductFamily&HStartForm2=True&HProductFamily=4%7CIOS

My search for a version supporting PPP, CEF and multihop VPDN returned a pretty long list. Some of the versions mentioned were 12.2(7), 12.2(7a), 12.2(8)T, 12.2(8)T1, 12.2(8) and a number of other versions. I suggest you use this tool to pin point an IOS which meets your requirements. I would also suggest that you use a GD version only.

Re: VPDN IOS12.2.11T multiple the login domain not work

Hi MOHAMAD ,

I have tested all IOS version from your seggestion . PPP on CEF work well but another problem still have . I forgot inform you about radius attribute from IOS12.2.11T , IOS12.2.11T1 its can send any radiusattribute to LNS .I was tested send "Session-Timeout=300" to LNS . then LNS ->show caller time :--> it tell session-timeout 5:00 and since another IOS version dosen't accept all attribute from radius . Now I'm still want IOS12.2.11T make multiple login domain .I have notice IOS12.2.11T it seem radius make newer future .I show you below (include multiple domain bug) :

====

It seem if debug radius format like IOS12.2.12A multiple login domain will work . Today I have upgrade from 12.2(6) to 12.2.12a already just fixed PPP and CEF for VPDN first . but still need the Radius Attribute for control LNS from IOS12.2.11T .

Thanks
