[cisco-bba] 7204vxr as LNS - provider is LAC

[Nathan Downes]

Hi James,

I thought that solved it, I didn't have a source-ip set so I set source-ip
to .29 but it still appears to fail due to unreachable .28??

>From what I gather I get the SCCRQ and for some reason a SCCRP is not making
it back, then tunnel is killed.

Hi Nathan,

Have you made a configruation mistake in your VPDN group maybe?
Perhaps you can share your config, that is always helpful.

You have this in your logs:


Jul 31 18:22:04.352: L2TP tnl   08060:________:     remote ip set to
202.10.4.147
Jul 31 18:22:04.352: L2TP tnl   08060:________:     local ip set to
203.111.114.28
...
Jul 31 18:22:04.352: L2TP tnl   08060:00003A1E:     local ip set to
203.111.114.29

Then this:

Jul 31 18:22:11.348: L2TP       _____:________: I StopCCN, flg TLS,
ver 2, len 75
...
Jul 31 18:22:11.352: L2TP       _____:________:        "203.111.114.28
is unreachable"
....

Have you got a mismatch between you "source-ip" on the VPDN group and actual
interface IP?

Cheers,
James.
