Hi Andy,<br>I think you need to configure lcp reneg always and clear the tunnel.<br>Even if this doesnt work, try setting ppp mrru in the template.<br>And even if this doesnt work raise case as suggested by Tony :)<br><br>

Andy Saykao<br>> Subject: RE: [cisco-bba] VPDN session stuck in wiccn
state<br>> ?<br>><br>><br>> Hi Andy,<br>><br>> I've pretty
much out of ideas now then, sorry :(<br>><br>> If you've opened a case
with TAC, you may just have to wait<br>> for them to<br>> sort it out
with you. I would press them to find out what<br>> that state of<br>>
"wiccn" means.. If it's not a valid state, then it's coming<br>> from
within<br>> the IOS code somewhere and they should be able to trace
it<br>> and find<br>> where. Keep requesting escalations on your case
until it<br>> gets to someone<br>> who knows/cares.<br>><br>> You
could try downgrading to a different IOS, unless you<br>> definitely
need<br>> something in the special release you are using to make it<br>>
work.<br>><br>> If it's only tunnels from one provider, is it from all
of<br>> their LAC, or<br>> a subset of their LAC
?<br>><br>><br>> regards,<br>>
