0xAAAA would match PPPoE over ATM using AAL5 LLC encapsulation format.

Is this something you are normaly accepting ?

I'm getting quite a lot of these debug logs for some customers:

Jun 30 13:49:32.465: Vi14 : I UNKNOWN(255) [Not negotiated] id 3 len 43690
Jun 30 13:49:32.469: Vi14 LCP: O PROTREJ [Open] id 2 len 6 protocol (0xAAAA)
Jun 30 13:49:40.841: Vi8 : I UNKNOWN(255) [Not negotiated] id 3 len 43690
Jun 30 13:49:40.841: Vi8 LCP: O PROTREJ [Open] id 228 len 6 protocol (0xAAAA)

Any idea what it might be?

PS: Router is a 7206 (12.3(1)) - used as a LNS.

PPPoE (LLC/SNAP) & PPPoA (VCMUX) is done by our telco's router which forwards l2tp
sessions to our router. We just terminate the l2tp sessions.

Is this a problem with telco's router or with customer's modem?

Most customers don't have such debugs...

That's pretty strange. It looks like a SNAP encapsulated IP packet
that we are receiving. You can see the 0xAAAA03 000000 0800 LLC/SNAP
header which indicates an IP packet and then it goes right into a
0x4500 IP header.
