Re: DVMRP Tunnel

Hi,

Not inhibited by any knowledge, but reading RFC1075 chap 4, I would  
say that:
- There's no setup protocol between tunnel endpoints,
- you'll see modified IP header options and the addresses of the  
tunnel endpoints.

Thanx,
Jaap

decoded
as IGMP traffic?  Does it masquerade as something else?

Does anyone have traces of a successful DVMRP tunnel being set up  
and in
operation?
