Hi Dennis,
But I believe I don't advertise this route. Where this route come from ? And
what is a martian address space ?
Thanks

Mark,
I believe the message is stating that the (254.192.2.52
<http://254.192.2.52/> ) is a martian address space. Which should not be
globaly advertised. Check out the this link.
http://www.ietf.org/rfc/rfc3704.txt
Someone correct me if I'm wrong.
thanks,

Dear CCIE Lab Group,
Can anyone give me explanation what is the meaning of this message :
%BGP-6-NEXTHOP: Invalid next hop (254.192.2.52) received from FEC0:234::4:
martian next hop
I'm currently establishing bgp ipv6 using frame-relay.
R4----FR DLCI 403 ----------FR DLCI 304-----R3
I already map the link local address also to each of the router but still
have the same mesaage. But route advertisement on both router looking good
though. No problem with route exchange. Just wondering what is this message
all about.
And Anyway, do I have to map link local address for bgp ipv6 over frame
relay ?
Have tried with no mapping link local address, still works fine
