*) eoip/eoipv6/gre/gre6/ipip/ipipv6/6to4 tunnels have new features:
tunnels go down when no route to destination;
tunnels go down for 1 minute when transmit loop detected, warning gets logged;
I’ve built an OSPF network with eoip tunnels so that I can deliver pppoe to my edge routers, but I keep getting the tunnels dropping out.
I have trouble with “loop detect” too
When OSPF start announce route’s (no metter dinamic,static), eoip report - “transmit loop detected, downing interface for 60 seconds”
