Answered Question
May 1st, 2009

Hello! Please help me to understand debug output (file attached). Interface Virtual-ppp1 gets up for 1 minute, no traffic can pass through and then interfaces goes down. I am trying to investigate the cause.

I have this problem too.

Under virtual interface, "no peer neighbor-route".

No, you can ignore CRYPTO errors. This message belongs to ipsec lan-to-lan that should be installed over l2tp tunnel. But as I said tunnel is not working and disconnects after 1 minute.

While investigating disconnect cause I wander about this debug output:

000527: *May 1 19:15:07.141: Vp1 IPCP: Install route to

Is it possible to disable route installation by IPCP?

My router (871) is connected to provider ethernet, and gets its Fe4 ip address by DHCP. To connect to the internet router needs to establish L2TP tunnel to provider equipment. Connection goes well (interface virtual-ppp1 - up) but no traffic can pass it and connection drops in one minute. I suppose that IPCP installs route to provider L2TP gateway via L2TP tunnel so this gateway becomes unreachable. I want to disable IPCP route installation.
